ZHA/M/ZHA/M pneumatic diaphragm angle adjusting valve

ZHA/M/ZHA/M pneumatic diaphragm angle adjusting valve, is the new product based on pneumatic angle valve of our plant, keep the original reliable action, small fluid resistance, light size, small size. Widely used in chemical, petroleum, power station, light industry, textile, metallurgy industrial processing for automatic control

Structure principle

ZH（A/B）M pneumatic diaphragm angle adjusting valve, made up of ZH（A/B）M pneumatic diaphragm multi-spring actuator and VM sleeve 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.
