Description
The Watts 0278480 Relf 174A-2-125 is a bronze pressure relief valve designed for hot water boilers, direct-fired water heaters, and storage tanks with indirect heaters. It protects these systems from possible harm brought on by an excessive build-up of pressure. As a safety feature, the valve opens and lets go of pressure when it reaches a set pressure threshold in this example, 125 psi. This keeps your HVAC system operating safely and helps prevent equipment problems. It guarantees dependable performance by fending off freezing, sticking, and caustic water conditions. With a pressure relief setting of 125 psi, the valve can handle high-pressure ratings of up to 12,170,000 BTU/hr. Interestingly, it’s a crucial safety precaution for HVAC systems rather than an operating control.
