Two-stage pressure reducing valves are used for low-pressure output, Where pressure precision and outlet flow requirements are high, Can be used with various gas cylinders and gas pipelines, The valve body reduces pressure in 2 stages, Outlet pressure is more stable than that of ordinary single-stage reducing valves.
● Body and diaphragm adopts hard sealed type.
Body Thread: 1/4"NPT(F).
● 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.
