ZMABN pneumatic diaphragm seat regulating valve

Advantage：large stock in common models,special models could be custom-made!

Details

ZMABN pneumatic diaphragm seat regulating valve, a pneumatic film multi spring actuator and valve seat.
Model ZHAB multi spring actuator to replace the old ZMAB executing mechanism, has the advantages of low height, light weight, convenient installation advantages repair.
Two seat valve has two valve, ball, thrust fluid on the spool, the opposite direction, the size, the unbalanced force is small, allowing a large pressure difference, the rated flow coefficient than the single seat valve with the diameter of the large, but the leakage of the valve is single seat valve.
Suitable for reliefThe dew is not strict, valve and pressure clean medium large occasions.
