Structure principle

ZH（A/B）S－64 pneumatic diaphragm angle adjusting valve, made up of ZH（A/B）pneumatic diaphragm multi-spring actuator and VS－64 angle valve

Principle: when pneumatic signal input into diaphragm room of actuator, diaphragm produce thrust, it compress spring, drive putter to move valve spool move up and down, change the throttling area between valve spool and valve seat, regulate flow of media.

ZH（A/B）S－64 pneumatic diaphragm angle adjusting valve, action mode: air off and air on
