OFR Filter Pressure Reducing Valve

Turn the adjusting screw clockwise and adjust the force of the torsion spring to press the valve piece downward, so that the connected spool and bottom plate move downward, at this time a pathway is formed above the spool base, from which the gas source pressure is led.

When the outlet pressure reaches the set value, it is transmitted to the bottom of the valve plate through the output pressure sensing hole, and the pressure of the torsion spring is kept in a constant state.

When the outlet pressure of the automatic filter is higher than the set pressure, it is transmitted to the bottom of the valve plate by the outlet pressure sensing hole, and the opening between the valve plate and the frame opens, so that the outlet pressure is transmitted to the torsion spring cavity and discharged to the air to maintain the set pressure.

Filtered pressure relief valve features.

1、Outlet pressure additional balanced poppet provides rapid response

2、With correct pressure adjustment function for suitable pressure control

3、Integrated control piston with lip seal for long service life.

4、Full flow pressure gauge.

5、Light pressure locking knob with protective cover.

6、Compact structure and easy maintenance

Precautions for the use of the filter pressure relief valve.

Daily maintenance of the filter pressure reducing valve should frequently check the manometer on the filter pressure reducing valve to observe whether the pressure fluctuates with the fluctuation of air pressure. If the pressure in the air fluctuates with the fluctuation of air, the pressure regulator is malfunctioning. You can try to adjust the regulator adjustment knob, if not, replace the filter cartridge pressure reducing valve carefully. Air filter pressure reducing valve because unstable air pressure will affect the life of the phone. In addition, the filter pressure reducing valve should be discharged regularly. The new filter pressure reducing valve can automatically open when the pressure reaches a specific pressure. Older filters and pressure reducing valves should be opened regularly with the drain valve below to prevent moisture. Typically, the drain will be every 15-30 days.
