Hattersley Fig 425 PN25 Pressure Reducing Valve

The Altecnic / Caleffi 313 Relief Valve with Gauge (Product Code: 313560) is an essential component for domestic hot water systems and heating setups. Designed to safeguard hot water cylinders and boilers, this valve is tailored to ensure optimal safety by releasing excess pressure. Upon reaching the designated discharge pressure, the valve automatically opens, venting to the atmosphere and preventing hazardous pressure levels that could jeopardise the boiler, hot water storage cylinder, and nearby personnel. This model is supplied complete with a built-in pressure gauge for added convenience and monitoring.
