Description
The Watts 0382570 Relief Valve is an essential part of HVAC systems and a safety element for safeguarding the pressure vessels including water heaters and boilers. This particular model is 1” x 1-1/4” valve, 30 PSI pressure and 1300M BTU capacity and is part of the 740-1-30 series. In other words, a puncture relief valve acts like an automatic shutdown valve that opens and releases pressure that is higher than a set limit, in this case, 30psi. This is avoided because some internal pressures may lead to explosions.
