OFR Filter Regulator

Turn the adjusting screw clockwise to adjust the force of the torsion spring, pressing the valve plate downward and causing the connected valve core and base plate to move downward. At this point a passage is formed above the valve core base, from which the gas source pressure is drawn.

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

When the outlet pressure of the fully automatic filter is higher than the set pressure, it is transmitted through the outlet pressure sensing hole to the bottom of the valve plate; the opening between the valve plate and the frame opens, allowing the outlet pressure to be transmitted to the torsion spring chamber and discharged into the air, maintaining the set pressure.

Features of the filter-type pressure relief valve:

1. The outlet-pressure auxiliary balanced poppet valve provides a rapid response.

2. It has accurate pressure adjustment, enabling suitable pressure control.

3. Integral control piston with lip-type seal for long service life.

4. Full-flow pressure gauge.

5. Light-pressure locking knob with protective cover.

6. Compact structure, easy to maintain.

Precautions for use of the filter pressure relief valve:

Daily maintenance of the filter pressure reducing valve: regularly check the pressure gauge on the filter pressure reducing valve and observe whether the pressure fluctuates with the air pressure. If the pressure in the air fluctuates with air fluctuations, the pressure regulator is faulty. Try adjusting the adjustment knob of the pressure regulating valve; if that fails, carefully replace the cartridge pressure reducing valve. The air filter pressure reducing valve: unstable air pressure will affect the service life of the equipment. In addition, the filter's pressure reducing valve should be drained periodically. New filter pressure reducing valves open automatically when the pressure reaches a certain level. Older filter and pressure reducing valves require periodically opening the drain valve below to prevent moisture. Generally, drainage occurs once every 15–30 days.
