General installation size Air Pressure Balance Relief Valve for Cement Silo Top
Brief intriduction
Pressure relief valve is an essential device for silo system. When the air pressure of the silo is too high or too low which reaches the preset value, the PRV will automatically open to balance the inside pressure with outside, thus the damage of the silo can be avoided. When the pressure is balanced, the PRV will automatically close without manual intervention.
All contact parts are made of carbon steel, on request from stainless steel. The cover can be made from stainless steel or plastic, seals are according to actual application.
