1-1/4" MPT Hansen EZ-SRV™ Cartridge Relief Valve with EZ fitting

Hansen EZ-SRV™ Cartridge Pressure Relief valves protect refrigeration pressure vessels and other refrigeration system components from excessive pressure. If an abnormally high pressure occurs, the cartridge pressure-relief valve will open to relieve the excess pressure, preventing potential damage to equipment and injury to personnel. EZ-SRV™ valves are built in strict conformance with both ASME Boiler and Pressure Vessel Code requirements and ISO 4126 Safety Devices for Protection of Excessive Pressure. Each valve bears the ASME code symbol of certification (UV) and CE mark. Valve capacities are rated by the National Board of Boiler and Pressure Vessel Inspectors (NB). Refrigeration pressure-relief valves are recommended for replacement at least every five years. However, if a relief valve has discharged, it must be replaced as soon as possible. Valve replacement with the Hansen EZ-SRV™ is fast and easy, saving significant time and expense compared to traditional relief valves. The cartridge valve can be replaced more safely than previously available pressure-relief valves.

A 1/4" gauge valve installed with a tell-tale pressure gauge can indicate overpressure of a valve and if pressure is present when servicing, the 1/4" gauge valve can also be used to safely bleed-off residual/pressure between the three-way manifold valve and the EZ-SRV™ valve.

This relief valve is only meant for gas services and have a threaded connection style. 

Please specify the pressure setting your purchase must be set to.

The valve includes an EZ-SRV Cartridge insert as well as the EZ-fitting body, which has a 1/4" NPT connection on the side for additional accessories and comes fitted with a hex head plug.

Additional accessories such as a gauge valve or a HG27 gauge must be purchased separately and are not included with this product.
