It is our quality commitment to focus our resources to provide our customers with first class products at a competitive price, that are designed, manufactured, inspected and tested in accordance with our customers, specifications and that comply with all international standards.With respect to the facts that the current industrial standards do not always take into consideration the likelihood and consequences of possible deterioration in service, related to specific service fluids or the external environment in which they operate. Our customers are requested to keep an open line of communication withNEWAY technical research center utilizes the most advanced computertechnology to improve the existing products and develop the new lines, this includes a highly educated and trained engineering team and a comprehensive internal computer network which links the entire operations of design, manufacturing and administration.NEWAY design philosophy is to develop a safety and cost-efficient valve, we introduced the latest AUTO CAD and I-DEAS software for all our new product design research which include the advanced finite element analysis to virtually verify the new design prior to production, this has resulted in dramatically reducing the new product design time and ensure a safety and cost efficient final product.NEWAY technical personnel are always ready to offer on line or on site technical training and support for all of its distributors, agents and end users.Fire safe is standard design of all NEWAY ball valve.Technical InnovationAPI 6D API 607API 6FA BS 5351BS 6755ANSI B16.34ANSI B16.10ANSI B16.5MSS SP-25MSS SP-55 NACE Std MR0175SHELL MESCAPI 598 Fire Safe Test CertificateTest FacilityTest ChartCNC LatheThe latest computer technology are also widely applied in NEWAY for valve manufacturing, this include a large number of numeric control machines (Machining center, CNC horizontal and vertical lathe, CNC drilling machine) and ERP management system which significantly improve our machining quality and process control. NEWAY also employes a number of conventional lathe with capacity up to machine 48ball valve.NEWAY manufacturing philosophy is to ensure stable quality and just in time delivery.4.2M Lathe CNC Lathe Automatic welding MachineMachining CenterCNC DrillingNEWAY developed an extensive and advanced inspection and test facilities to control the quality from rough castings or forgings to final products. These facilities enable us to do Radio graphic test, Ultra-sonic test, Dye-penetrate test, Magnetic test, Positive Material Identifier (PMI), Impact test, T ensile test, Hardness test, Fire safe test, Cryogenic test, Vacuum test, Low fugitive emission test and Hydro-static test.NEWAY Quality Assurance is dedicated to the pursuit of a zero defect valve, and this has resulted in the company having more quality qualifications and end user approval than most of our competitors. NEWAY is certified by ISO 9001 (certificate under DNV) and API 6D (registered no. 6D-0285) and our off-shore platform valves are type approved by ABS. Moreover, NEWAY is the first valve manufacturer in China to be certified to CE/PED (category IV, mode B+D, certificate under B.V.), All of NEWAY soft seated ball valves are fire safe tested and certified by Lloyd s Register.Part number identificationControlled Stem & Stuffing Box FinishFor the elimination of air pollution, it is essential to control the fugitive emissions leakage of various chemicals from valves in your chemical plant. NEWAY low emissions ball valves installed with our emissions defense packing have been designed and tested to m e e t t h e 100 P P M m a x i m u m e m i s s i o n l e v e l (acceptance test per Shell SPE 77/312). This is NEWAYstandard specification for all series BA, B and BB flanged floating ball valve.The stem surface finish is controlled between Weather proofbelleville-spring washerLow Emission packingFire Safe Seat SealingAdditionally, the fire safe metal seat can prevent the line pressure erosion on soft seat and minimize soft seat creep deformation. All NEWAY floating valves fire safe is designed and test certified in accordance with API 607.When static are generated and concentrated on the ball, the spring-loaded pins installed on ball, stem are provided to ensure electrical continuity throughout the valve.Anti-Static DeviceStem lower end is integral T shaped designed to be blow-out proof. It is internally inserted and functions as the backseat for assured stem sealing at all pressuresBlow-out Proof StemBefore FireBodyStemPacking ClosureBall StemPackingBallSeatBodyPackingStemAnti-Static DeviceClosureBodyBallGasketClosureWhen non-metal sealing material are decomposed or deteriorated by a plant fire, the upstream line pressure pull the ball into contact with the metal seat lip beneath the soft seat to shut off the line fluid to minimize the internal leakage.Design Feature:Live Loaded Gland FlangeLow Emission PackingLive loading is designed to provide gland load retention, compensating for expected in-service consolidation of the packing. A set of Belleville-Spring Washers are used on each gland stud to help exert a continuous compressive force on the gland follower flange and therefore reduce fugitive emissions from the stem packing. NEWAY standard Belleville-Spring Washers are protected by a weatherproof cap to keep them free from environmental contamination, resulting in a longstable life.The packing set is a combination of parallel and vertical layer sealing elements, which are made of expanding graphite in die-formed rings and have features of heat resistance, less stress relaxation and low creep. With this special structure, it allows for a low-friction on rotary & rising stem valves, therefore providing the stabilized seal performance for long cycle life.For medium and low temperature service, the standard V shape PTFE packing rings are installed for lowemission control.Floating Ball Valve Design FeatureLow Emission Control2963161861171514128137541110Series FE1 Ball ValveRegular port, uni-body, end entry designBlow-out Proof StemInternally inserted and functions as the backseat for assured stem sealing at all pressuresMetal-to-Metal Sealing When non-meatl sealing is deteriorated by fire,ball floats to shut off the line fruidEmission-free Graphite primary gasketIndex noPart123456789Index no PartBody Closure BallGland Flange Lever Seat Ring Stem Gland Gasket101112131415161718Grounding Washer Packing Set Stop Plate Thrust Washer Retainer Washer Bolt Rotaining SpringSeries FE1 Ball ValveSeries FE1 Ball ValveRegular port,uni-body,cast steel,end entry designClass 150LBWeight KgW mmH mmL mmD mmd mmSizeinDimensionsWW DLdHWDLddHGear Operator1 / 22 3101 / 23 / 411-1/222-1/23468101 / 23 / 49.512.71930385164761141441879.512.712.71925.43851647610215220325412.719108117127165178191203229267292330140152545964901021121211662082463035459120140140160265265265300400 300 * 400 *120140 1.72.72.985.008.7112.416.6624.38541011502.83.61638111071817962416135151412Series FB2 Ball Valveavailable in size from to 12 full port or witnessed and certified by Lloyd s Register.Double "D" Stem HeadProvides mounting of the lever handle alwaysin parallel to the flow passage Blow-out Proof Stem Internally inserted and functions as the backseat for assured stem sealing at all pressuresEmission-free Graphite primary gasket Metal-to-Metal SealingWhen non-meatl sealing isdeteriorated by fire,ball floats to shut off the line fruid easily for installation of gear, motor or pneumatic actuator 123456789Body Closure Ball Yoke Gland Flange Seat Ring Stem Gland Gasket 101112131415161718Grounding Washer Packing Set Thrust Washer Stud Nut Bolt Bolt Spring Steel BallSeries FB2 material specifications Series FB2 Ball Valve Two-piece,split body,cast steel,side entry design Full Port Size in D mm L mm H mm W mm Weight Kg Reduced Port Size in D mm L mm H mm W mm Weight Kg d mm 150L B Gear Operator Dimensions W H D L Full Port WH d D L Reduced Port W 123456789101112131415161718No. Part Standard Stainless Steel Sour Service Low TemperatureServiceASTM A352-LCB ASTM A352-LCB ASTM A182-F316ASTM A216-WCB ASTM A216-WCB PTFE ASTM A182-F316ASTM A182-F316316SS + Graphite Graphite PTFE PTFE ASTM A320-L7M ASTM A194-7M ASTM A320-L7M ASTM A320-L7M S.S.S.S.ASTM A216-WCB ASTM A216-WCB ASTM A105/ENP ASTM A216-WCB ASTM A216-WCB PTFE ASTM A182-F6a ASTM A276-420316SS + Graphite Graphite PTFE PTFE ASTM A193-B7M ASTM A194-2HM ASTM A193-B7M ASTM A193-B7M S.S.S.S.ASTM A351-CF8M ASTM A351-CF8M ASTM A182-F316ASTM A351-CF8M ASTM A351-CF8M PTFE ASTM A182-F316ASTM A182-F316316SS + Graphite Graphite PTFE PTFE ASTM A193-B8ASTM A194-8ASTM A193-B8ASTM A193-B8S.S.S.S.ASTM A216-WCB ASTM A216-WCB ASTM A105/ENP ASTM A216-WCB ASTM A216-WCB PTFE ASTM A182-F6a ASTM A276-420316SS + Graphite Graphite PTFE PTFE ASTM A193-B7ASTM A194-2H ASTM A193-B7ASTM A193-B7S.S.S.S.Body Closure Ball Yoke Gland Flange Seat Ring Stem Gland Gasket Grounding Washer Packing Set Thrust Washer Stud Nut Bolt Bolt Spring Steel Ball 1 / 23 / 411-1/222-1/23456810121 / 2131925385164761021251522032543051310811712716517819120322935639445753361014059637697107142152178252272342345479591301301602302304004007001100 300 * 300 * 400 * 600 *1303/4*1/2*3/43/4*1/2*3/41*3/4*11-1/2*1-1/22*1-1/2*22-1/2*2*2-1/23*2-1/2*34*3*46*4*68*6*810*8*1012*10*121.782.003.517.2311.0515.022.036.058.0110.0195.0309.0346.02.29131925385164761021522032541319253851647610215220325430519117127165178190203229394457530610152828510011512015316219129034044282130130160230230400400460 300 * 300 * 400 *130 3.04.57.09.515.016.029.548.0123.0212.0230.03.5Series FB2 Ball Valve122019178111354197161021181631415296Blow-out Proof Stem Internally insertedand functions as the backseat for assured stem sealing at all pressuresSeries FB2 Ball Valve Two-piece, split body, forged steel, side entry design This series ball valves are featured with two-piece bolted with flanged end body and floating ball.

They are available in size from 2to 48Wide range of body and trim material is available for service00temperature from -46C to 200C and pressure rating from ANSI class 150 to 1500 or for sour service to NACE Mr0175.For 6 inch and larger NEWAY Trunnion mounted ball valveswill be installed with a sealant injection fittings on both stemand seats. When the sealing materials (seat sealing or stemo-ring) are damaged or decomposed by fire or otheraccidental causes, leakage from the seat and stem can beprevented by injection of sealant into these fittings. Fitting isalso internally installed a second check valve to providesbackup sealing. Emergency sealant injection system Cavity Pressure ReliefEach ball seats shut off the line fluid independently on the upstream and downstream side, allowing double block o p e r a t i o n. W h e n t h e p r e s s u r e i s simultaneously applied to both sides of the ball in closed position, the valve bore and the body cavity will be isolated from each other, and the residue within the body cavity can be released through the drain plug.Double block and bleed Top flange Injection Closure Gland Body Ball SeatThe stem is made separately from the ball; The lover end of the stem is designed with an integral collar to be blowout-proof.Antistatic device is a standard feature of NEWAY ball valve . A spring-loaded pin assures the electrical continuity, between ball ,stem and body, so as to avoid sparks during turning of the stem to open and close the valve, which could be dangerous in caseof hazardous area installation.Super Fire safe designExternal leakage preventionLeakage from the valve stem area isprevented by double sealing with 2 O-rings and gland gasket. Leakagethrough the valve body joint is alsoblocked by double sealing with O-ringand body gasket. After a fire hasdeteriorated O-rings, gland gasket,body gasket and stem firesafe packingare the measure that prevents externalfluid leakage. When non-metal materials such as O-ring, seat insert and spacer aredecomposed or deteriorated by fire, theedge of the metal seat preloaded by theBall to shut off the line fluid to minimize internal leakage through the valve bore.
