Safety · Pressure-Vacuum Valves

Designed for installation on bulk storage tanks, the Storagetech Model 140 pressure relief valve is designed to protect the tank against excessive internal pressure. In the closed position, the weight-loaded pallet and diaphragm assembly are held tightly against a seal to prevent vapor loss to the atmosphere. As the internal tank pressure increases due to product filling and vapor generation, and when the unit set pressure is reached, the diaphragm opens and releases gas to the atmosphere. The opening set point can be selected within a range between +2.0 mbar and +60 mbar (+0.8 in. W.C. and +24 in. W.C.), and the valve will close when the tank returns to a safe pressure.
