The Caleffi Loose Nut Pressure Relief Valve is a specialised, trade-grade replacement safety cartridge engineered specifically for the Caleffi MK2 Multibloc inlet control group. Its primary function within an unvented domestic hot water system is to safeguard the storage cylinder from high pressure caused by thermal expansion. If the system pressure rises to a critical level, the valve opens automatically to discharge a controlled amount of water, protecting the tank and connected pipework from over-pressurisation.
