Apollo Valves 513-GFBK-NAA-0125 Bronze Safety Valve

Apollo Valves 513-GFBK-NAA-0125 Bronze Safety Valve is a bronze-bodied safety relief valve from Apollo’s 5xxGF family, engineered to protect steam, air/gas, and non-hazardous liquid systems from overpressure. It features a 1-1/4-inch NPT male inlet and a 2-inch NPT female outlet, enabling secure installation in compact piping runs. The part number suffix 0125 denotes a 125 psi factory-set pressure, making it suitable for standard overpressure protection on typical low- to mid-range systems. Constructed with a bronze body and a metal seat, it employs a stainless-steel spring to actuate the relief mechanism, delivering reliable response while remaining compatible with steam, air/gas, and non-hazardous liquids in Apollo installations. Intended for ASME Section VIII applications, this valve is designed to provide robust, code-compliant overpressure protection in boilers, heat exchangers, process vessels, and associated piping where a bronze safety relief device is appropriate.
