n When partial pump flow is used for individual functions
n At high intensity usage
n To create simple system solutions when a number of functions with different flow rates is demanded n When system layout is spread out
n At simultanious operation of functions n Power control and energy conservation
n
Reduce energy losses at idling and transportation
Suitable when;
System with variable pump and LS
Save energy, design advises
n Avoid to mix light and heavy loads from the same pump.
n Avoid to mix large and small flow demands from the same fixed pump.
n Never control max flow with line mounted restrictors.
n Always use the pump regulator to set maximum work pressure when you are using a variable pump. The pressure limiter of the valve needs to be set at least 30 bars above.
n Avoid to limit valve work port pressure with the chock valves, use the build in individual work port feed reducer.
n Make sure that the cylinders are correctly connected to the
valve, the valve is normally adapted to the cylinder ratio.

液压传动的优缺点
缺点
噪声； 外部泄漏，会造成环境污染，即使是少量的矿物油漏泄， 也会毁坏大片的地表水；不过现在已越来越普遍地使用可 生物降解的液压油液； 易受污染，液压工作介质中的污染物质会导致介质变质、 元件磨损、系统性能恶化； 对环境温度较敏感，温度过高或过低均会影响甚至破坏元 件的可靠性和系统的性能。 液压油液中的气体会破坏系统的刚性，引起气穴，导致液 压泵和其它液压元件的损坏。

However, air should be lubricated to assure maximum seal life.F442 lubricating oil is recommended. This oil is speciallyformulated to provide peak performance and maximum service life from air-operated equipment.InstallationCAUTION: DO NOT RESTRICT THE INLET TO POPPET VALVESRestriction of the inlet can starve the air supply to the pilot section of internally piloted poppet valves and result in slow shifting or failure of the valve to shift properly. Always connect the supply line directly to the inlet of the valve using the full pipe size of the valve inlet. Never use a quick coupling to connect a poppet valve to the air supply. On valves with a small inlet port, use of an upstream surge tank may be required at lower operating pressures to insure an adequate air supply and proper operation.Parker PneumaticN Series ValvesSingle Solenoid, Locking manual override, internal “P” pilot 140 PSI, standard service, junction box w/ light.Body In / cyl Exhaust 2-way, 2-position 3-way, 2-position 3-way, 2-positionSingle Remote Pilot, 1/4" NPT remote pilot port with internal pilot return.BodyIn / cyl Exhaust 2-way, 2-position3-way, 2-position 3-way, 2-positionSingle Solenoid, Locking manual override, internal “P” pilot 125 PSI, standard service, P-pilot junction box w/ light.Body In / cyl Exhaust2-way, 2-position 3-way, 2-position 3-way, 2-positionSingle Remote Pilot, 1/4" NPT remote pilot port with internal pilot return.Body In / cyl Exhaust 2-way, 2-position 3-way, 2-position 3-way, 2-positionParker PneumaticN Series Valves Model Number Index“N” Series 3/8", 3/4" & 1-1/4" Body Sizes - Solenoid ‘L’ PilotNote: BSPP is to the ISO 228 standard, and requires an R-BSPT male fitting.“N” Series 1-1/4" Body Sizes - Solenoid Hi-Flow ‘P’ PilotR-BSPT male fitting.Parker PneumaticReplacement PilotsDescriptionHazardous duty L-pilot NEMA 4 L-pilot Hazardous duty L-pilot - UL & CSA K0451025**N/AOverride typeLocking Non-Locking Locking Non-Locking Hazardous duty with override K0453025**K0452025**NEMA 4 with overrideK2553025**K255202549** Voltage code - 49 & 53N Series Valve Replacement PartsReplacement PilotsDescription Standard L-pilot Continuous duty L-pilot Override type Locking Non-locking Locking Non-locking Basic with overrideK0653035**K0652035**K0853025**K0852025**JIC with junction box & override K0656035**K0655035**K0856025**K0855025**JIC pilot with junction box &override & indicator lights (120VAC only)K0659035**K0658035**K0859025**K0858025**** Voltage code - (reference model index for availability)Replacement PilotsDescription Heavy duty P-Pilot Override type No override Non-locking Locking Basic with overrideK1351045**N/A N/A JIC with junction box & override N/A K1355045**K1356045**JIC Pilot with junction box & override & indicator lights (120VAC only)N/AK135804553K135904553** Voltage code - 49 & 53Voltage Code **Voltage Coil 60Hz 50Hz DC 19" Leads 72" Leads 4224——K593099—43—24—K593098—45——12K593094—49—— 24K593097—51——48—K59325453115——K593108—58—230—K593111—Coils for L-Pilot Operated ValvesCoils for P-Pilot Operated ValvesVoltage Code **Voltage Coil60Hz 50Hz DC 19" Leads 72" Leads 4012——K593007—41,4224—6K593003—45*——12K593010—49*——24 (Standard)K593014—79——24 (ArcSuppressed)K593271—51*——48—K59318553*120110—K593025—57*240240—K593035—60240220—K593035—61——120K593041—* Indicates voltages approved for solenoid operators designed for use inhazardous locations.NVoltage Code* *Internal Pilot -3/8" & 3/4" Basic BodyKey 3/8" Body3/4" Body Inch mm Inch mm A 1.5640 2.1354B 1.5038 1.9449C1.8146 1.3434D .5614.5614E 3/8-16UNC 7/16" deep 3/8-16UNC 9/16" deepF 1.7544 2.2557G 1.5038 1.5038H 5.921507.14181J3.1981 3.7595K 1.8847 2.4462N 1.4437 1.7845P 7.361968.58218Q2.31593.0984216891351051A 10AKey 3/8" Valve 3/4" Valve Description4*H14510H13676U-cup (3/8), o-ring (3/4)5K493002K493009Stem6K202001K202002Lower piston assy.7*H14509H13676U-cup (3/8), o-ring (3/4)8H17811H17813Washer (2)9H06326H06332Stop nut (2)10K103035K103053Bottom cap (N.C.)10A K092020K092034Bottom cap assy.

阀门培训内容
阀门培训内容一、前言阀门是流体输送系统中的控制部件，具有截止、调节、导流、稳压、分流、溢流、泄压等功能。
阀门广泛应用于石油、化工、天然气、电力、冶金、食品、制药等行业。
为了提高阀门使用效率，保障生产安全，降低维护成本，本培训旨在使参训人员全面了解阀门的结构、原理、选型、安装、调试、维护及故障处理等方面的知识。
二、阀门基础知识1. 阀门分类阀门按照结构可分为截止阀、球阀、蝶阀、闸阀、截止止回阀、安全阀等；按照驱动方式可分为手动、电动、气动、液压等；按照连接方式可分为法兰连接、螺纹连接、焊接连接等。
2. 阀门结构及工作原理阀门主要由阀体、阀盖、阀杆、阀瓣、密封圈等组成。
阀门通过改变阀门通道的截面积，实现流体的截止、调节、导流等功能。
不同类型的阀门具有不同的工作原理，如截止阀通过升降阀瓣实现截止，球阀通过旋转球体实现截止，蝶阀通过旋转蝶板实现调节等。
3. 阀门材质及密封面材料阀门的材质和密封面材料对阀门的使用性能和寿命具有重要影响。
阀门材质包括铸铁、碳钢、不锈钢、合金钢等；密封面材料包括橡胶、聚四氟乙烯、金属等。
根据流体介质的性质，选择合适的阀门材质和密封面材料。
三、阀门选型与安装1. 阀门选型（1）满足生产工艺要求；（2）保证流体介质安全、清洁、无泄漏；（3）操作简便，维护方便；（4）经济合理，降低成本。
2. 阀门安装（1）阀门安装方向应正确；（2）阀门与管道连接应牢固、严密；（3）阀门安装位置应便于操作、检修；（4）阀门安装高度应符合设计要求。
四、阀门调试与维护1. 阀门调试阀门调试主要包括手动操作、电动操作、气动操作等。
调试过程中，应检查阀门启闭是否灵活、密封是否严密、驱动装置是否正常。
对于特殊阀门，如安全阀、减压阀等，还需进行功能调试。
2. 阀门维护阀门维护主要包括日常检查、定期保养、故障排除等。
日常检查应关注阀门密封性能、驱动装置、连接部位等；定期保养应进行阀门清洗、润滑、更换密封圈等；故障排除应遵循先分析原因，后采取相应措施的原则。
