關(guān)注次數(shù)：

Summary.
ZMAW pneumatic diaphragm control valve, ZSRW, ZSCW pneumatic piston control valve input control signal (4-20mADC or 1-5VDC) air to control operation, adjustment of the fluid is suitable for the suspended particles concentration, turbidity and slurry fluid. Clean medium, can choose the valve plate with soft seal (rubber ring, PTFE ring) to reduce leakage (up to 0.01%), high temperature and high pressure conditions can choose three eccentric hard seal valve.

Characteristic.
Simple and compact structure, convenient processing,
Easy to make large caliber, with self-cleaning function,
Small resistance coefficient, flow capacity.
