The primary purpose of a pressure relief valve is for safety of system operators and property protection by venting fluid from an over pressurized vessel. Relief valves meet industry needs for overpressure protection in chemical, petrochemical, refinery, power generation and other commercial applications. Relief valves such as Consolidated relief valves, Crosby relief valves, Farris relief valves all come in various material bodies such as alloy, carbon steel, and stainless steel and may require special alloys for specific applications.

The Groth Model 2050A Emergency Pressure Vacuum Relief Valve is designed to provide emergency relief capacity beyond that furnished by the normal operating pressure or vacuum relief valves on the tank. The Model 2050A valve protects the tank against rupture, explosion or implosion that could result from excessive internal pressures or vacuum conditions caused by fire or rapid emptying of the tank. As excessive pressure builds up, Model 2050A relieves, then re-seats when overpressure has been dissipated.

The Groth Model 2000A is designed to provide emergency relief capacity beyond that furnished by the normal operating pressure relief valve on the tank. The valve protects the tank against rupture or explosion that could result from excessive internal pressures caused by fire. Removable stops can be provided which restrict the lift of the cover.

This lightweight, spring-loaded emergency vent (pressure relief only) is used on aboveground storage tanks, as a code requirement, to help prevent the tank from becoming over-pressurized and possibly rupturing if ever exposed to fire. This vent must be used in conjunction with a “normal vent.” Correct application of this vent requires proper vent size and selection for the tank system in order to meet the specific venting capacity.
