Pressure Relief Valve

The pressure relief valve is an essential device for silo. In case the air pressure inside the silo reaches the minimum or maximum preset value, the vacuum relief valve will run automatically to balance the pressures inside and outside. So, the silo and the accessory equipment can be protected from being damaged. When the pressure is in specified range, the pressure reducing valve will restore automatically. No manual intervention is required during the whole process.

1. Waterproof head cover: glass fiber reinforced plastics
2. Valve plate: carbon steel, dedicated black seal
3. Valve body: carbon steel, gray powder coated surface
4. Connection of the pressure relief valve: clamp connection with seal ring

Factory Settings: 500mmH2O-20mmH2O

Note: since the proximity switch of the negative pressure will be affected by the opening and vibration of the proximity switch for the positive pressure, the proximity switch of the negative pressure may be connected as well when the positive pressure proximity switch is connected.
