ZSCW pneumatic piston regulating butterfly valve

1、 Product Details

Product model:ZSCW

Product Name: Pneumatic piston regulating butterfly valve

ZMAW pneumatic thin film regulating butterfly valve, ZSRW, ZSCW pneumatic piston regulating butterfly valve can be controlled by input control signal (4-20mADC or 1-5VDC) gas source for operation, suitable for regulating suspended particle fluids and concentrated and turbid slurry fluids. For clean media, valve plates with soft seals (rubber rings, PTFE rings) can be used to reduce leakage (up to 0.01%). For high temperature and high pressure conditions, a three eccentric hard seal valve body can be used.

Features: Simple and compact structure, easy processing,

Easy to make into large caliber, with self-cleaning function,

Low resistance coefficient and high flow capacity.
