Pressure Relief Valve

Start with the system's maximum allowable working pressure (MAWP) and required relieving capacity. Then determine whether you need ASME Section IV or XIII for hot water, Section VIII for steam, or non-code for air/gases. Match set pressure, temperature, and connection size to your system — our engineers can help you verify compatibility.

We carry 1,294 models across 12 brands, including APOLLO, WILKINS, HAM-LET, AQUATROL, Watts, PLAST-O-MATIC, KUNKLE VALVE, Dayton, CASH ACME, CASH VALVE, HAYWARD, and VICKERS. This range covers ASME-coded steam and hot water valves, non-code air/gas valves, and corrosive or ultra-pure liquid service valves.
