● Overview
ZJHQ, ZJHX pneumatic film tee confluence , shunt valve using thin-walled cylindrical spool -shaped window -oriented , unlike the plunger -shaped piston guide bushing . Equipped with multi-spring actuator , has a simple structure , light weight , small size, and easy disassembly . Widely used for precise control of gases, liquids and other media process parameters such as pressure, flow , temperature, level maintained at a given value . Adapted to a fluid flowing through the three-way valve into Road or the merger of two fluids through the three-way valve into a fluid situation .
The series has three confluence and three shunt two kinds. Nominal there PN16, 40,64; nominal diameter range of DN25 ~ 300. For fluid temperature from -60 ℃ to +450 ℃. Leakage standard grade Ⅳ, flow characteristics are linear , parabolic two kinds.
