Description

Hotpot pressure relief valve used to alleviate pressure damage to pressurised fluid systems, such as in calorifiers. The relief valve is set at a predetermined level that will divert some of the fluid away when the pressure in the system reaches that point. This is to stop the system getting damaged by high pressures, but also sets a level that allows the system to do its job and not vent water too much.
