Apollo Valves 500 Series ASME Section VIII Div 1 Pressure Safety Relief Valves

The Apollo® 500 Series pressure safety relief valves are ASME Section VIII Division 1 capacity-certified safety relief valves for overpressure protection of pressure vessels, piping, and process equipment in steam, air, compressed-gas, and liquid service. With set-pressure ranges from 5 to 1,200 psig at 800°F maximum and 1/2 inch through 2 inch inlet connections, the 500 Series protects boilers, air receivers, gas-distribution headers, compressed-gas storage, and steam-condensate systems against overpressure events.

Available in bronze, carbon steel, and stainless steel body construction with lapped metal seats (O-ring and PCTFE seats optional), and configurable with either a screwed cap or packed lift lever, the 500 Series meets ASME Section VIII Division 1 certified-capacity requirements and is manufactured in the USA.
