ZMA pneumatic film single seated/double seated /sleeve control valve
ZMA pneumatic film single seated/double seated /sleeve control
valve has learned from partial merits of Cv3000, which is composed of
multi spring adjustable diaphragm actuator and double seated control
valve. This valve is lighter than ordinary double seated control valves
while its outlook is nice. BY using balanced valve core, differential
pressure is large; flow rate is big, which is suitable for low requirement
of leakage.
