Summary

The 30W01 self-operated micro- pressure control valve It is widely used for controlling after-valve pressure (mmH2O) of non corrosive gas or air with pressure no higher than1.4MPa, working temperature no higher than 120℃(or 150℃) and pressure control range of 0.14 - 7.2KPa. It is widely applied in gas sealing pressure control devices of various oil products, chemicals and liquid storage tanks.
