Watts 0121470 Relief Valve Refrigerant Precise Timing Cycles: Maintains anThe Watts 0121470 (LF174A) 3 4" water pressure relief valve is a critical safety component designed for hot water heating boilers and hydronic systems. Engineered with a lead free copper silicon alloy body, this valve ensures compliance with low lead regulations while providing a high capacity discharge of 1,320,000 BTU hr at a fixed 75 PSI set pressure. The large diaphragm operated design minimizes the risk of seat sticking, while the non mechanical
