Relief Valves

This 3/4 inch pressure safety relief valve is used in commercial and industrial applications for low pressure, steam heating boilers and process equipment. It consists of a bronze body construction with NPT threaded female inlet and threaded female outlet (drain) connection, stainless steel spring, a top-guided stem, and a non-stick Teflon® disc-to-metal seating. The pressure relief is set at 30 psi (2.1 bar).

This 3/4 inch lead free vacuum relief valve is suitable for low pressure steam and water service, and is ideal for use in domestic water heaters and supply tanks. This valve automatically allows air to enter into the piping system to prevent vacuum conditions that could siphon water from the system and damage water equipment. It consists of a lead free brass body construction with NPT male inlet connection, and a protective cap. Maximum working pressure is 200 psi.
