Watts Regulator series 374A boiler pressure relief valves are used in hot water boiler applications to protect against excessive pressure on all types of hot water heating boiler equipment. It consists of an iron body construction with forged bronze inlet connections, non-metallic disc-to-metal seating, stainless steel spring, and test lever. Series 374A 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 and shall not be used as an operating control.

• Iron body with forged brass inlet
• Seat located above drain, water cant be trapped and sediment cant foul seat
• Non-mechanical seat-to-disc alignment will not stick or freeze
• Each hot water space heating boiler shall be equipped with a pressure relief valve set to relieve below the maximum boiler working pressure
• Non-metallic disc-to-metal seating
• Bronze inlet wetted parts
