pressure relief valve

EZ-SRV Cartridge Relief Valve

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.

Rupture Disc Assemblies, Gauges, and Pressure Switches

Hansen rupture disc assemblies (RDAs) are used to indicate which pressure-relief valve has discharged. A pressure-relief valve will re-seat after discharging. However, a rupture disc remains open after bursting. (A rupture disc is not a stand alone safety device.) An installed pressure gauge or switch (required by code) provides a visual or electronic indication that the rupture disc has burst.
