ZMAW.ZSCW pneumatic piston regulating butterfly valve
Product introduction:
ZMAW.ZSCW pneumatic piston valve control signal input (4-20mADC or 1-5VDC) source to control operation, simple and compact structure, convenient processing, easy manufacture of large caliber, self cleaning effect, low resistance coefficient, flow capacity. Fluid suitable for suspended particles and regulation of concentrated and muddy fluids. Clean medium, can choose the valve plate with soft sealing (rubber ring, PTFE ring) to reduce leakage (up to 0.01%), high temperature and high pressure conditions can choose three eccentric hard seal valve
