ZMAS pneumatic film Angle regulating valve

ZMA/BS-220, 320 series pneumatic thin instantaneous Angle commercial pressure regulator is composed of pneumatic eruption multi-elastic actuator and angular pressure release valve.
ZMAS angular high pressure pneumatic diaphragm regulator adopts permeable valve seat structure, the valve seat is easy to replace and the sealing performance is good. The valve core is a plunger shape, which is used for the core under the condition of differential pressure. The head is surfacing tungsten cobalt alloy, which has the advantages of cavitation resistance and anti-flushing, greatly improving the service life.
Widely used in chemical industry, oil refining and other industries, especially suitable for synthetic nitrogen, urine industrial commercial pressure and commercial pressure difference medium regulation.
