Description
The Watts 0382456 is a ¾ inch x 1 inch iron boiler pressure relief valve, typically measuring around 12 inches in total length. It safeguards hot water heating boilers by automatically releasing excess pressure that can build up during system operation. The valve remains closed during normal operation, but if pressure surpasses the preset limit (usually 75 psi), the valve opens and discharges water to prevent potential boiler ruptures. Made for durability with iron construction, it tolerates temperatures ranging from 40°F to 175°F and can handle both natural gas and LP gas systems. While the listing mentions 24V and 50/60 Hz, these specifications likely refer to compatible control systems rather than the valve’s direct operation, as it functions mechanically based on pressure relief. By automatically releasing excess pressure, the Watts 0382456 safeguards your hot water boiler from potential damage and ensures safe system operation.
