TECHNICAL BULLETIN Logix 520MD SeriesDigital PositionerFCD LGENTB0520-01 09/09IntroductionThe Logix 520MD Series combines superior positioning and tuning functions with convenient setup and powerful, easy to use diagnostic tools unlike other positioners that have only one gain. The Logix 520MD positioner uses a multi-variable variable gain tuning algorithm. This allows the positioner to make large step changes with minimal overshoot, while achieving the resolution to respond to very small step changes.The Auto-tune procedure cycles the actuator to produce a measured response and selects gain values that provide appropriate actuator performance. The Auto-tune function includes a gain modifier selector that can be used to increase or decrease the calculated gain in order to achieve optimal performance. By setting the Auto-tune on/off DIP switch, the tuning mode can be changed from auto to manual. The Logix 520MD Series positioners provide several preset gain settings with a locally adjustable gain set selector directly from the user interface on the positioner. If custom settings are desired, tuning sets can be modified with a handheld or with ValveSight™ software, to accommodate a wide range of actuator sizes and types.The 520MD, 521MD and 522MD models• Three versions:BasicAdvanced (Advanced includes pressure sensors)Pro (Pro includes pressure sensors and full featured valve diagnostics)• HART Command 1, 3, 9, 33 & 48• Burst Mode available for continuous data transmission• Position command with analog 4-20 mA loop current• Final value of command after characterization• Supply pressure (Advanced +Pro)• Stem position in percent• Onboard temperature sensor to measure local positioner ambient temperature• Stroke speed limiter (configurable through HART or ValveSight™)• Step test, friction test, HRL, data logger• DTM Available2Features and Benefits3Principle of OperationThe Logix 520MD positioner is a digital positioner with various options. The positioner consists of three main modules:1. The microprocessor based electronic control module includes direct local user interface switches2. The piezo valve based electro-pneumatic converter module3. The infinite resolution valve position sensor.The basic positioner operation is best understood by referring to Figure 1. The complete control circuit is powered by the two-wire, 4-20 mA command signal. The analog 4-20 mA command is passed to the microprocessor, where it is compared to the measured valve stem position. The control algorithm in the processor performs control calculations and produces an output command to the piezo valve, which drives the pneumatic amplifier. The position of the pilot valve in the pneumatic amplifier is measured and relayed to the inner loop control circuit. This two-stage control pro-vides for more responsive and tighter control than is possible with a single stage control algorithm.The pneumatic amplifier controls the airflow to the actuator. The change of pressure and volume of the air in the actua-tor causes the valve to stroke. As the valve approaches the desired position, the difference between the commanded position and the measured position becomes smaller and the output to the piezo is decreased. This, in turn, causes the pilot valve to close and the resulting flow to decrease, which slows the actuator movement as it approaches the new commanded position. When the valve actuator is at the desired position, the pneumatic amplifier output is held at zero, which holds the valve in a constant position.Figure 1: Logix 520MD Principle of Operation45The Logix 520MD for HART ApplicationsComplete local configuration• Local status and alert messages • T uning (Auto-tune function and manual adjustment)• Jog buttons to manually adjust 100% position • Easy-to-install 4-20 mA analog feedback card optionFigure 3: Logix 520MD SeriesFigure 2: ValveSight ™ Dashboard for Logix 522MDAdvanced DTM and Pro diagnostics6ValveSight™ FDT/DTM TechnologyFlowserve’s ValveSight™ DTM software helps manage field devices by combining the features of field network hardware and the Hart 500MD communication protocols using FDT/DTM technology with the Logix 500MD series positioners. ValveSight™ is a complete software package, featuring a unique and easy to understand health status of the device that shows not only problems, but also the magnitude of developing problems.ValveSight™ also has configuration and calibration screens to fully support the Logix 500MD positioner family. Addition-ally, the user can access customized reports for all configuration, calibration and event data. Flowserve’s ValveSight™ DTM opens a ‘window’ to the device and allows immediate views with live feedback on all active device sensors includ-ing valve stem position, control signal, friction, response time and other important system metrics.ValveSight™ DTM software enables communication between the software and field device networks using the HART or FF protocol and provides access to the 24/7 diagnostic information from field devices. Using FDT/DTM technology maintenance personnel can access any Logix 500MD series positioner on the network from a single workstation. Addi-tionally, the software has the capability to store configuration and calibration history and view event logs for each digitalpositioner accessible through the network.71Limited function.

General DescriptionThese two-stage valves are used to limit or control pressure by directing up to the total system uid ow to reservoir when system pressure reaches the setting of the valve. System actuators are thus protected against overload.Each relief valve incorporates a vent port that can be connected to a separate pilot control valve to remotely control or unload system pressure.Two types of valve are presented in this catalog:CG2V-***, 10 series: relief/sequencevalve with integral manual adjustment of pressure setting.CG5V-***, 20 series: relief valve with solenoid operated pilot valve for loading/unloading.A third type, KCG-*, 10 series, with proportional pilot control valve, is described in catalog 2324.Features and Bene tsClose matching to application requirements from choice of four adjustment control ranges covering 3 to 350 bar (44 to 5000 psi).Electrical on/o load from solenoid controlled models.Remote parallel control by other pilot valves connected to “vent” port.High machine productivity resulting from full system ow being available for work output until system pressure is very close to valve setting.Pressure override optimized without detriment to other performance parameters.Excellent repeatability and stable performance from cartridge-type design of mainstage parts.Low o -load power wastage.International mounting interfaces.Low installed cost and spacerequirement from high power/size ratios (more than double that of many conventional designs).Pressure Relief and Sequence ValvesVickers by Danfoss®Pressure ReliefAF439975160003en-000101Side drain portIf a valve with an integral, reverse free- ow check is required, use a type RCG valve, as in catalog 429.BFor Valves with Manual Adjustment Only(F3-)CG2V-***-1*123411(-1)5For Valves with Manual Adjustment Plus Electrical Load/Unload(F3-)CG5V- ***12349-D(-*)-(V)M-***(-L)-*5-2*67810112Functional SymbolsRelief valve, manually adjusted,CG2V-***-1* modelSequence valve, manually adjusted,CG2V-***-1-1* modelSolenoid controlled relief valve, pilots internally drained, CG5V-***-D-2* modelModel Codes3Operating DataData is typical with oil at 22 cSt (106 SUS) and at 50 C (122F)4VentingSystem pressure can be dropped to near-zero by connecting vent port X to reservoir through a suitable pilot valve, e.g:5Control Data for CG2V ValvesManual adjustment of pressure setting described in “Installation Dimensions ”.Hydraulic Remote ControlRemote adjustment of pressure setting can be made by a pilot relief valve,substituted for the vent valve in the diagram. Suitable pilot relief valves are described in catalogs 411 (type C-175valves) and 409 (type CGR-02 valves).Control Data for CG5V Valves Vent FunctionThe solenoid operated pilot valve isVickers by Danfoss model type DG4V-3S, with spool type “0B ” (ref. catalog 2015). When the solenoid is de-energized, the CG5V relief valve is unloaded by venting the pilot drain to port T. Note that any back pressure at port T is additive to the minimum possible unloaded pressure,and is also additive to the on-load pressure setting.When the solenoid is energized the pilot ow is blocked to bring the relief valve on load. For this function port X would normally be blocked (e.g. no connection from the mounting face). Further remote control pressure settings are possible by connecting port X to suitable pilot relief valves via other DG4V-3S type directional control valves.1106Hydraulic FluidsAll valves can be used with:Antiwear hydraulic oils (class L-HM)Invert emulsions (class L-HFB)Water glycol (class L-HFC)Phosphate ester (class L-HFD), adding “F3-” pre x at model code .The extreme viscosity range is from 500 to 13 cSt (2270 to 70 SUS) but the recommended range is 54 to 13 cSt (245 to 70 SUS).For further information about uids see “Technical Information ” lea et 920.Temperature LimitsMinimum ambient: –20C (–4F)Maximum ambient:For CG2V valves: 70C (158F)For CG5V valves with coils listed inmodel code and at 110% of rated voltage:Coil type and frequencyMax. ambient temperature Dual frequency coils at 50 Hz at 60 Hz65 C (149F)65 C (149F)Single frequency (50 Hz) coils at 50 Hz 65C (149F)DC coils70 C (158F)Fluid temperatures (all models)PetroleumoilWater-containing Min.–20C (–4F)+10C (+50F)Max.*+70C (+158F)+54C (+129F)*To obtain optimum service life from bothuid and hydraulic system, 65 C (150F)normally is the maximum temperature except for water-containing uids.For synthetic uids consult uid manufacturer or Danfossrepresentative where limits are outside those of petroleum oil.Whatever the actual temperature range, ensure that viscosities stay within the limits speci ed in the “Hydraulic Fluids ” section.Contamination Control RequirementsRecommendations on contamination control methods and the selection of products to control uid condition areincluded in Vickers by Danfoss publication 9132 or 561,“Vickers by Danfoss Guide to Systemic Contamination Control ”.

VALVE MEMBER FOR PILOT OPERATED VALVES
专利名称:VALVE MEMBER FOR PILOT OPERATED VALVES发明人:JAMES P. FROMFIELD申请号:AU4598279申请日:19790412公开号:AU4598279A公开日:19791011专利内容由知识产权出版社提供摘要:A valve member including a flexible diaphragm movable into and out of engagement with a valve seat to close and open the valve, respectively. A rigid support plate rests against the face of the diaphragm opposite the face which engages the valve seat. A stem projects from the plate, through a hole in the diaphragm and into the orifice surrounded by the valve seat. The diaphragm and plate are not rigidly secured together, so that the entire diaphragm is free to flex with respect to the support plate. A pilot passageway may extend completely through the plate and stem. The stem is long enough such that the lower end of the pilot passageway is below the plane of the valve seat even when the valve is open. An abutment, such as an outwardly projecting bead, on the lower end of the stem prevents accidental separation of the plate and diaphragm before they are assembled with a valve.申请人:AUTOMATIC SWITCH COMAPNY更多信息请下载全文后查看。

Solenoid valves VZWF, force pilot operated, NPTKey features and overview FunctionNormally closed solenoid valve with diaphragm and forced lifting. When the solenoid is energised, the differential pressure from the secondary side of the diaphragm is reduced via the servo hole. The effective differential pressure lifts the diaphragm away from the valve seat. If there is no differential pressure, the diaphragm is lifted directly by the solenoid.

SunHydraulicsTechnicalTips-SequenceValves
Sun Hydraulics Technical TipsSequence ValvesAPPLICATIONSSequence CartridgesSun sequence cartridges are normally closed pressure control elements designed to modulate flow from port 1 (inlet) to port 2 (outlet) (like a relief valve) as long as the pressure at port 1 exceeds the pressure setting plus the back pressure at port 3 (the control chamber drain). Unlike relief valves, sequence valves generate a constant pressure at the inlet port irrespective of the pressure on the outlet port. When pressures at port 1 and port 2 both exceed the setting of the valve, the valve goes “full open”, or “sequences”. This function is achieved by draining the spring chamber separately to tank. Sequence valves can be used to sense pressure (port 1) in one circuit and then open and supply oil to a secondary circuit (port 2) at a predetermined pressure.• A typical application would be when maintained clamping pressure is required in the primary circuit while work is being performed in the secondary circuit.• A sequence valve can be used as an accurate pressure limiting valve where there is varying back pressure on the tank port.• Another application would be to maintain a minimum “pilot pressure” in an open flow circuit. (Unlike a relief valve, the “full open” feature of a sequence valve, above its setting, tends to eliminate parasitic losses in the system at working pressures. (See Figure 1 on page 2.)• A sequence valve can also function as an adjustable bypass pressure compensator. (See Figure 2 on page 2.)Sun Hydraulics’ sequence valves have flow capacities up to 120 gpm (460 L/min) and are fully adjustable over a range of operating pressures up to 5000 psi (350 bar) (6000 psi [420 bar] intermittent). (Air piloted versions have lower pressure ranges.) Prior to shipping, all Sun sequence valves are factory pressure set with a flow of 4 gpm (16 L/min).NOTE: All Sun three port sequence cartridges are functionally interchangeable (i.e. same flow path and same cavities for a given frame size).This drawing is not a real circuit and is intended for descriptiononly.Design Concepts and FeaturesThree Port Direct Acting Pressure Generating Sequence Cartridges —SX*A and SC*A (with reverse flow check)The performance parameters optimized in Sun’s SX*A and SC*A sequence valves are:• Suitable for use in load holding applications.• Reverse flow from port 2 to port 1 is blocked. (Use SC*A with reverse flow check if reverse flow is required.)• Low hysteresis (reseats at 90% of valve setting) and very low leakage (10 drops per minute at reseat).• There is no pilot flow from the drain port, but this port must not be plugged, as this could cause malfunction.• Fast opening and closing (2 ms typical response time).• Insensitivity to varying oil temperature and oil-borne contami-nation.• Reliable cold oil closing and exceptional hot oil stability (no oscillation).• Rugged, robust, construction withstands high pressure shocks or back pressure.• The pressure override curve is steeper than pilot operated versions.NOTE: See General Sequence Valve Note on page 3.Two Port Direct Acting Pressure Regulating Sequence Cartridges – SXCB and SCCB (with reverse flow check)The performance parameters for Sun’s SXCB and SCCB sequence valves are the same as the SX*A and SC*A valves, except there is no port 3; the spring chamber is referenced to atmosphere. Additional performance parameters include:• Two port sequence valves are only available in Series 1 frame size (15 gpm/60L/min).• Over a period of time, external fluid “weepage” may occur.(Approximately 1 drop per 4000 cycles)Three Port Pilot Operated Pressure Regulating Sequence Cartridges – RS*CSun’s RS*C balanced piston, two stage, sequence cartridge valves are optimized to operate over a wide flow range, up to 120 gpm (460 L/min). Performance parameters include:• Flatter pressure override curve as compared to direct acting versions.• Stable operation.• The pilot orifice is protected by a 150 micron stainless steel filter screen. (Continued on page 3.)These drawings are not real circuits and are intended fordescription only.(Continued from page 2.) • The minimum pressure setting is determined by the mainspool bias spring, which establishes the lowest pressure atwhich pilot flow will open the main spool. • Reverse flow from port 2 to port 1 is blocked. (If reverse flow is required, use an external check or an SC*A with reverse flow check.) • Low hysteresis and low spool leakage between port 1 and port 2 and is frame size dependant (approximately 2-5 in 3/min per 1000 psi [32-82 cc/min per 70 bar]).• Pilot flow out of port 3 will be about 20 in 3/min (0,33 L/min) with 1000 psi (70 bar) at port 1. The actual pilot flow isdependent on the pressure at port 1 and will rise and fall inrelation to this pressure. (Go to Sun’s web site to view performance graphs on individual RS*C product pages.)• Valve may be “blocked” by shutting off the pilot flow at port 3 (with a two-way valve, for instance), thus causing the valve to remain closed even at its set point. If port 3 is then “vented” to drain, the valve will operate normally, opening at its set point.NOTE: See General Sequence Valve Note at bottom of page.Three Port Pilot Operated Pressure RegulatingSequence Cartridges – RS*SSun’s RS*S balanced poppet , two stage, sequence cartridges have similar features to the RS*C series except a poppet replaces the spool in the main stage. The modified performance parameters include:• Slightly higher hysteresis (+/- 2%). • Pressure override curve greater than RS*C balanced pistonvalve, but lower than direct acting versions.• Seated poppet design achieves very low leakage (10 drops/min at reseat). • Poppet design almost eliminates cavitation erosion that can occur in manifolds adjacent to the valve discharge holes.• RS*S sequence valves are only available in Series 4 size(120 gpm/460 L/min).NOTE: See General Sequence Valve Note at bottom of page.Three Port Pilot Operated Kick-Down Sequence Cartridges – SQ*BSun’s SQ*B balanced piston kick-down sequence cartridges shift completely open after the pressure setting for port 1 is attained. The valve will stay open as long as the pressure at port 1 (inlet) exceeds the pressure at port 2 (outlet). Performance parameters of Sun’s kick-down sequence valves include:• Very accurate trigger point (valve setting). • Typical response time of 40 ms.• At nominal full flow(s), pressure drop is very low, reducing heat generation. (Approximately 50 psi (4 bar) for SQEB at 10 gpm (40 L/min.)• Low spool leakage in closed mode (before reaching “trigger point”) from port 1 to port 2 or port 2 to port 1. (Leakage is frame size dependant and varies approximately 2-5 in 3/min per 1000 psi [32-82 cc/min per 70 bar].)• If reverse flow is desired, a separate free flow check is required.• Once opened, the valve can only be reset by stopping allflow through the valve. Centering or reversing the directional valve will usually reset the sequence valve. • Should not be used in load holding applications. • Pilot flow out port 3 of 20 in 3/min (0,33 L/min), and will riserelative to the pressure rise on port 1. (See individual valve performance graphs on Sun’s web site.) • The pilot orifice is protected by a 150 micron stainless steelfilter screen.NOTE: See General Sequence Valve Note at bottom of page.Three Port Air Controlled Pilot Operated Sequence Cartridges — RS*ESun’s RS*E balanced piston sequence valves use compressedair over a diaphragm instead of an adjustable spring to provideremote control of the valve pressure setting. Performance parameters/features include: • Hydraulic pressure setting is directly proportional to air pressure setting (pilot ratio equals 20:1; i.e. 10 psi (0,7 bar) air pressure is equal to a 200 psi (14 bar) valve setting).• Maximum operating pressure = 2000 psi (140 bar). • Maximum air pressure should not exceed 150 psi (10 bar). • Most other performance characteristics are similar to RS*C relief valves. • The pressure at port 3 determines minimum setting and must not exceed 1000 psi (70 bar).May be useful as an explosion proof valve where remote pressure control is required.Four Port Pilot Operated Vented Relief (Sequence) Cartridges – RV*D (Also see Tech Tips for Relief Valves)Sun’s RV*D balanced piston , two stage, vented, pressure regulating cartridges provide both a drain port (port 4) plus a remote pilot port (port 3). These cartridges combine the features of pilot operated, vented, relief valves with those of pilot oper-ated sequence valves. Performance parameters include:• With drain port (port 4) connected to tank, the valve is insensitive to any back pressure on port 2.• Can be used as a dual pressure sequence valve by connect-ing the pilot (port 3) to a remote, selectable, pilot source. (The main stage pressure setting must be set higher than that of the remote relief.)• Valve may be “blocked” by shutting off the pilot flow at port 4. As with the RS*C sequence valves previously described, if port 3 is then “vented” to drain, the valve will operate nor-mally, opening at its set point.• Any pressure at the drain port (port 4), is directly additive to pressure setting at the inlet (port 1).General Sequence Valve Note:Any pressure at port 3 (drain) is directly additive to the pressure setting at port 1 (inlet).FunctionDescriptionNominal CapacityModelCavitySymbol3 PortDirect Acting without Re-verse Flow Check15 gpm (60 L/min.) 30 gpm (120 L/min.)SXCA SXEAT-11A T-2A3 PortDirect Acting with Reverse Flow Check 15 gpm (60 L/min.) 30 gpm (120 L/min.)60 gpm (240 L/min.) 120 gpm (480 L/min.)

PILOT VALVE
专利名称:PILOT VALVE 发明人:ESKIL AURELL 申请号:AU4518179申请日:19790316公开号:AU4518179A 公开日:19790920专利内容由知识产权出版社提供摘要:A pilot valve is described for control of a pulse valve for e.g. production of pulses of compressed air. The pilot valve comprises a housing having an inlet and an outlet, a movable valve element disposed inside the housing, and means for switching said valve element between a closed and an open position, said inlet and outlet communicating in the open position. At least a portion of the interior of the housing presents in one plane a circular shape, the outlet being formed as a radial slot from this portion around at least a part of the periphery. The valve element is designed as a flexible disc which in the closed position is located in said plane to seal the slot with its outer edge at the inner side of the housing. Said means are arranged to switch the valve element to the open position by giving the disc a curved shape so that the outer edge no longer covers the slot.申请人:SVENSKA FLAKTFABRIKEN, AB更多信息请下载全文后查看。

D761 SeriesServovalves ISO 10372 Size 04The actual flow is dependent upon electrical command signal and valve pressure drop.The flow for a given valve pressure drop can be calculated using the square root function for sharp edge orifices:∆p Q = Q N∆pNQ [gpm] = calculated flowQ N[gpm] = rated flow∆p [psi] = actual valvepressure drop∆p N[psi] = rated valvepressure dropThis catalog is for users with technicalknowledge.T o ensure that all necessarycharacteristics for function and safetyof the system are given,the user hasto check the suitability of theproducts described here.In caseof doubt,please contact Moog Inc.D761 SERIES SERVOVALVESThe D761 Series flow controlservovalves are throttle valvesfor 3- and preferably 4-wayapplications.They are a highperformance,two-stage designthat covers the range of ratedflows from 1 to 16.5 gpm at1000 psi valve drop.The outputstage is a closed center,four-way sliding spool.The pilotstage is a symmetrical double-nozzle and flapper,driven by adouble air gap,dry torquemotor.Mechanical feedback ofspool position is provided by acantilever spring.The valvedesign is simple and rugged fordependable,long life operation.These valves are suitable forelectrohydraulic position,speed,pressure or force con-trol systems with high dynamicresponse requirements.Principle of operationAn electrical command signal(flow rate set point) is appliedto the torque motor coils andcreates a magnetic force whichacts on the ends of the pilotstage armature.This causes adeflection of armature/flapperassembly within the flexuretube.Deflection of the flapperrestricts fluid flow through onenozzle which is carried throughto one spool end,displacingthe spool.Movement of the spool opensthe supply pressure port (P) toone control port,while simul-taneously opening the tankport (T) to the other controlport.The spool motion alsoapplies a force to the cantileverspring,creating a restoringtorque on the armature/flapperassembly.Once the restoringtorque becomes equal to thetorque from the magneticforces,the armature/flapperassembly moves back to theneutral position,and the spoolis held open in a state of equi-librium until the commandsignal changes to a new level.In summary,the spool positionis proportional to the inputcurrent,and with constantpressure drop across the valve,flow to the load is proportionalto the spool position.2VALVE FEATURES¢2-stage design with dry torque motor¢Low friction double nozzle pilot stage¢High spool control forces¢High dynamics¢Field replaceable first stage filter¢Rugged,long-life design¢High resolution,low hysteresis¢Completely set-up at the factory¢Optional fifth port for separate pilot supplyD761 SERIESTWO ST AGE SERVOVAL VES3Operating Pressure*ports P ,X,A and B up to 5,000 psi port Tup to 5,000 psiT emperature RangeFluid -4˚F to 176˚F Ambient -4˚F to 176˚FSeal Material Viton,others on request Operating FluidCompatible with common hydraulic fluids,other fluids on request.Viscosity recommended 60 – 450 SUS @ 100˚F System Filtration:High pressure filter (without bypass,but with dirt alarm) mounted in the main flow and,if possible,directly upstream of the valve.Class of Cleanliness:The cleanliness of the hydraulic fluidgreatly effects the performance (spool positioning,highresolution) and wear (metering edges,pressure gain,leakage) of the servovalve.Recommended Cleanliness ClassFor normal operation ISO 4406 < 14/11For longer life ISO 4406 < 13/10Filter Rating recommendedFor normal operation ß10≥75 (10 µm absolute)For longer life ß5≥75 (5 µm absolute)Installation Operations Any position,fixed or movable.Vibration 30 g,3 axes Weight 2.3 lbs (4.0 lbs for steel body)Degree of Protection EN50529P:class IP65,withmating connector mounted.Shipping Plate Delivered with an oil sealedshipping plate.* Maximum special order is 5,000 psiD761 SERIESGENERAL TECHNICAL DA T AStandard ValvesHigh Response ValvesModel…T ype D761-………Mounting Pattern ISO 10372 -
