Altecnic / Caleffi 311 Series Safety Relief Valve 3/4" x 3/4" F x F 2.5 Bar - 311525

The Altecnic / Caleffi Relief Valve - Circlip Inlet - F0000412 is specifically designed for domestic hot water systems, providing essential protection for hot water cylinders and heating systems, including boilers and other vital components. This relief valve is chosen based on the required set pressure, and as system pressure increases, it opens to discharge excess pressure into the atmosphere when the predetermined threshold is reached. This crucial function prevents potentially hazardous pressure levels from accumulating within the system, ensuring the safety of both the boiler, hot water storage cylinder, and personnel in the vicinity.

Specification:

• Materials: Brass
• Set Pressure: 6 Barg
• Product Code: F0000412
• Notes: Compatible with MK3 Caleffi Multibloc

Invest in the Altecnic / Caleffi Relief Valve F0000412 for reliable pressure regulation and enhanced safety in your domestic hot water and heating systems.
