Classification And Selection Of Pneumatic Plastic Butterfly Valves
Oct 17, 2018

The pneumatic plastic butterfly valve has the advantages of strong corrosion resistance, light weight of the valve body and wear resistance, and its torque force is small, the pneumatic switch speed is fast, and it can be used for cutting off the pipeline fluid, or for regulating the flow rate and pressure. Pneumatic plastic butterfly valve body structure adopts the neutral line type, suitable for fluid: water, air, oil, corrosive chemical liquid. Applied to general pure water, raw water, sewage.

Pneumatic plastic butterfly valve body material is made of PPH, RPP, PE, PVDF, CPVC, UPVC raw materials. The sealing seat is made of EPDM or fluororubber (FPM), which can withstand most of the acid and alkali. The salt is corrosion from low to high concentration. According to different materials, the general temperature resistance is -14 ° C ~ 100 ° C, -40 ° C ~ 120 ° C, the pressure is in the range of 1.0 Mpa.

Pneumatic plastic butterfly valves in the medium used are generally clean liquids and gases, and can not contain particulate impurities, otherwise it will cause the object to scratch the seal ring, resulting in leakage problems!
