Bronze Body Safety Relief Valves for Pressure Protection only of All Types of Hot Water Heating Boiler Equipment; 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; Meets Requirements of the Buy American Act
This 1 1/4 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 setting is 45 psi (3.1 bar), with corresponding high ratings from 650,000 to 14,370,000 BTU/hr.
Pressure Steam Discharge Capacity 2265000 BTU/Hour at 45 PSI
