PRESSURE-RELIEF VALVES
PRESSURE-RELIEF VALVES
Designed to provide emergency relief from excessive pressure in refrigerant-containing vessels, they are built in strict conformance with ASME Boiler and Pressure Vessel Code requirements for safety relief devices. Each valve bears the ASME code symbol of certification (UV). Their capacities are rated by the National Board of Boiler and Pressure Vessel Inspectors. These tamper-resistant valves are accurately set and sealed by qualified technicians at the factory. They dimensionally replace their Henry Valve counterparts; yet, they have equal or slightly greater capacity, subsequently, no piping changes are normally required

RUPTURE DISC ASSEMBLIES AND PRESSURE SWITCHES
RUPTURE DISC ASSEMBLIES AND PR
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.)
