The air-operated gas regulator adjusts downstream pressure by controlling the compressed air pressure, controlling the downstream fluid pressure. Pressure can be set anywhere within the adjusting range, continuous control, achieving continuous, stepless downstream pressure regulation, supports remote, pneumatic and other control modes, downstream pressure is controlled by air pressure, may be equal, or varied at a set ratio, air control ratio 1: 1 to 1:100. Pneumatically controlled gas regulators are suitable for applications where fluid pressure requires remote or precise control.
● Piston type pressure reducing structure.
Body Thread: 1/2"NPT(F), 3/4"NPT(F).
● Built-in filter screen.
● Panel or wall mounting available.
●Can be controlled remotely, and other control modes including pneumatic control.
●compressed air pressure 0-7bar.
●Sensitive operation, high precision.
