Pressure Vacuum Relief Vents
Pressure Vacuum relief valves / valves are weight-loaded products designed to prevent tank deformation caused by the increase in internal and external pressure. They are produced with a wide range of materials according to the aggressiveness of the stored product.
When the tank internal pressure or external pressure reaches the valve pressure set pressure value, the loaded pallet is lifted to allow the overloaded pressure to vent to the atmosphere or to extend the pipe. The process is produced in 2 ways, with "scrubber" connection or atmospheric. Pressure losses on the vacuum side are given graphically with the products.
