When sizing a relief valve for a specific container, review the manufacturers data to confirm that the flow capacity of the valve is adequate.

Types H722 and H732 stainless steel (316/CF8M) relief valves resist rust and corrosion. Stainless steel makes it easy to remove the valve from the tank for periodic testing (as prescribed by DOT and Transport Canada), and permits standard tank couplings instead of the more costly flanged tank openings. Field Repairable valve seats allow for seat replacement without affecting relief set point. Tight fitting protective caps (P297 and P298) are standard on the valve to ensure no debris blocks the valve discharge.

The valves are identical except for valve body materials. All valves are constructed of brass unless otherwise noted. The H500 Manifold relief allows the changing of the valves while the tank is full to allow the valves to be inspected, repaired or replaced.
