WATTS®, 0121467, Pressure Relief Valve, Series: LF174A, 3/4 in Nominal, 60 psi Pressure, 250 deg F, Media: Water, Cast Copper Silicon Alloy Body, 2-3/4 in L x 4-1/2 in H Dimensions, Domestic
Lead Free cast copper silicon alloy body safety relief valves for pressure protection only of all types of hot water heating boiler equipment. Pressure range 50 to 150psi (3 - 10 bar) with corresponding high ratings from 2,459,000 to 14,370,000 BTU/hr. Female inlet and outlet connections. Sizes 3/4in. - 2in. (20 - 50mm). The LF174A features Lead Free construction to comply with Lead Free* installation requirements 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.
- Automatic reseating
- Seat located above drain, water cannot be trapped and sediment cannot 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
- Nonmetallic disc-to-metal seating
- As thermal expansion conditions develop, pressure builds up to the setting of the relief valve, This will cause discharging of small quantity of water
- Should operating controls fail, permitting runaway firing, the boiler water may reach steam temperatures, the valve will then open to discharge steam at the rate or faster than the boiler can generate it, thus restoring system pressure to a safer level
- The wetted surface of this product contacted by consumable water contains less than 0.25% of lead by weight
