Zero Differential Pressure Type Pilot Operated 2 Port Solenoid Valve Series VXZAirWaterOilHeated water High temperature oilClearanceBy providing a buffer and clearance,we reduced the collision sound of thecore when ON (when the valve isopen). Because of the clearance,when using highly viscous fluids suchas oil, the armature does not get stuckand the responsiveness when OFF(when the valve is closed) is improved.EnclosureIP65Improved armaturedurabilityFlame resistanceUL94V-0 conformedLow-noiseconstructionImpact noise reducedby the rubber bufferPiping variationsThread piping, One-touch fittingBody materialAluminium, Resin Air (VXZ2A3 )Water/Oil/Air/C37 (Brass), Stainless steelHeated water/High temperature oilBuilt-in full-wave rectifier type (AC specification)Improved durabilityService life is extended by a special construction.(compared with current AC specification)Reduced buzz noiseRectified to DC by a full-wave rectifier, resulting in abuzz noise reduction.Improved OFF responseSpecially constructed to improve the OFF responsewhen operated with a higher viscosity fluid such as oil.Low-noise constructionSpecially constructed to reduce impact noiseduring operation.Variations Fluid Body Size Applicable fluid ModelAirWaterOilHeated waterHigh temperature oilModelBodysizeOrifice diametermmøFor AirVXZ2첸0P.4VXZ2 A310APort sizeBodymaterial1/4, 3/8Aluminiumø10, ø12, ø3/8"ResinC37 (Brass)1/4, 3/8Stainless steelP.7For OilVXZ2첸3P.10For Heated waterVXZ2첸5P.13For Hightemperature oilVXZ2첸6Air10For WaterVXZ2첸2FluidP.16 For details, refer to pages 35 and 36.Features 1C37 (Brass)VXZ2 B415AVXZ2 C520AVXZ2 D625A15AirWaterOilHeated water1/2Stainless steelC37 (Brass)203/4Stainless steelC37 (Brass)25High temperature oil1Stainless steel
