Ordering Process

ZMAW pneumatic membrane control butterfly valve / ZSRW, ZSCW pneumatic piston control butterfly valve input control signal (4-20mADC or 1-5VDC) air source can control operation, simple and compact structure, easy to manufacture large diameter, with self-cleaning effect, small resistance coefficient, large flow capacity. It is suitable for the regulation of suspended solids and strong and turbid slurry fluids. Clean medium, can choose the valve plate plus soft seal (rubber ring, tetrafluoro ring) to reduce leakage (up to 0.01%), high temperature and high pressure can choose the three eccentric hard seal valve body. The order must be marked.
