Pneumatic Film Three-way Confluence and Shunt-off Regulating Valve
Pneumatic thin-walled window-shaped spool guide is used in the three-way flow and shunt control valv…
Description:
A, use: ZJHQ, ZJHX seriesPneumatic diaphragm three confluence, shunt valveThe cylinder shaped valve type thin window guide, the guide bushing is different from the plunger shaped spool.Equipped with multi spring actuator, has the advantages of simple structure, light weight, small volume, convenient disassembly and assembly etc..Widely used in the precise control of the gas and liquid medium in the process such as pressure, flow, temperature, liquid level is maintained at a given value.Suitable for a fluid through a three-way valve into the road or the outflow of both fluid through a three-way valve into the fluid situation. This series of products are three confluence and three shunt two.Nominal pressure PN16, 40, 64; nominal diameter range of DN25 ~ 300.Application of fluid temperature from -60 DEG to +450 DEG C.Leakage standard IV.Flow characteristics are linear, parabolic two.
