Watts Pressure Relief Valve: MNPT x FNPT, 1/2 in x 1/2 in, Copper Silicon Alloy

A Watts pressure relief valve protects hot water heating systems from overpressure. It automatically opens when system pressure exceeds its set point, discharging water to prevent equipment damage or failure. This ASME Section IV rated valve is commonly installed on boilers and storage tanks.

The Watts 1/2 LF53L-150 is a 1/2 in MNPT x 1/2 in FNPT pressure relief valve made of copper silicon alloy. It has an overall height of 3 1/2 in and is ASME Section IV rated for hot water applications. The valve body material resists corrosion in hydronic systems.
