Pressure Vacuum Relief Valve Top mounted, pipe-away, weight-loaded

Model No: 120

Storagetech’s Model 120 Pressure Vacuum Relief Valve provides protection to bulk storage tanks and vessels from over and under pressurization. The valves are mounted on the tank roof flange or a vent pipe from the vapour space.

In the closed position the pressure relief pallet and diaphragm assembly are held tightly against a seal to prevent the loss of vapour to the atmosphere. As the internal pressure in the tank increases, due to product filling and vapour development, the pressure in tank increases and in the event that the set pressure of the unit is reached, the diaphragm will open and discharge the gas into the atmosphere. The opening set-point is selectable from a range between +2.0 mbar and +60 mbar. (+0.8 inch W.C and +24 inch W.C) and the valve will reseal when the tank returns to a safe pressure.
