Bailey Birkett G4 Pressure Reducing Valve - Fig 2043

The Altecnic / Caleffi 312 Relief Valve - Pushfit - A312401CST is an essential component for domestic hot water systems, designed to safeguard hot water cylinders, as well as heating systems, including boilers and other critical components. This relief valve is specifically selected according to the required set pressure to ensure optimal performance. When the system pressure exceeds the predetermined discharge pressure, the valve activates, releasing excess pressure to the atmosphere. This vital function helps to prevent dangerous pressure levels that could potentially harm the boiler, hot water storage cylinder, and surrounding personnel.
