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

Sid Harvey C354-1R Pressuretrol Controller, SPST, 0.5-9 psi Adjustable, 3-3/8" W x 4-15/32" H x 2-1/4" D, Remanufactured

• The PA404 is a series 40 (2-wire, SPST) pressuretrol controller for use in 24, 120, 240 or 277 volt control circuits or in self powered (millivoltage) applications
• The PA404B is used with suspension-type unit heaters to make the fan circuit when a pressure rise indicates the presence of steam
• Each model contains an SPST micro-switch snap-acting switch
• Sensitive pressure-actuated diaphragm expands or contracts with pressure variations, moving a lever mechanism which operates the snap switch
• A screw on top of the case allows set point adjustment without removing the cover
• Differential is adjusted by means of a dial located inside the case
• Recommended minimum set point is differential setting plus 1-1/2 psi
• Tradeline value
• Stainless steel diaphragm sensor element
• Additive or subtractive differential type
• Makes at set point plus differential on pressure rise, breaks at set point on pressure fall
• 50 psi pressure surge
• 0.5-9 psi adjustable scale range,
