ZJHP (M) type pneumatic diaphragm regulating valve
Product Model: ZJHP (M) Product Features: ZJHP (M) Pneumatic Thin Film Regulating Valve
Product details
ZJHPThe small-sized pneumatic single seat regulating valve is composed of a new type of multi spring thin film actuator and a low flow resistance single seat valve, which meets the requirements ofIECStandard new generation universal valve products. The product has a low actuator height, light weight, and easy assembly and calibration; Low flow resistance single seat valves have the characteristics of smooth flow channels and high flow coefficients.
This product has reliable operation, high accuracy of flow characteristics, and a large adjustable ratio; Due to its compact structure and small external dimensions, it can be widely used in industries such as petrochemicals, pharmaceuticals, metallurgy, papermaking, and water treatment to control various fluid media.
