Specification Sheet1-1/2 IN Bronze Boiler Pressure Relief Valve, 30 PSI Spring Loaded, Soft seated, Automatic reseating
This 1 1/2 inch boiler pressure relief valve is used in hot water heating and domestic supply boiler applications to protect against excessive pressures on all types of hot water heating supply boiler equipment. It consists of a bronze body construction with NPT threaded female inlet and NPT threaded female outlet (drain) connections, non-metallic disc-to-metal seating, stainless steel spring, and test lever. It resists corrosive water conditions, sticking and freezing, and prevents water and sediment from being trapped in the seat. It is designed for emergency safety relief, not as an operating control. The pressure relief is set at 30 psi (206.8 kPa) with corresponding high pressure ratings up to 2,020,000 BTU/hr.
Features
- Seat located above drain; water can’t be trapped and sediment can’t foul seat.
- Non-mechanical seat-to-disc alignment will not stick or freeze.
- Water seal of high temperature resisting material isolates spring working parts from water during relief.*
