**Altecnic / Caleffi Relief Valve - Circlip Inlet - F0000419** The Altecnic / Caleffi Relief Valve - Circlip Inlet - F0000419 is an essential component for domestic hot water systems. This valve safeguards hot water cylinders and protects boilers and other system components in heating applications. With a selection based on the required set pressure, this relief valve operates efficiently to maintain safety in your system. When system pressure rises, the valve activates at its designated discharge pressure, releasing excess pressure to the atmosphere. This crucial function prevents dangerous pressure levels that could jeopardise the integrity of the boiler, hot water storage cylinder, and the safety of personnel in the surrounding area. **Product Specifications:** - **Materials:** Brass - **Set Pressure:** 6 Barg - **Product Code:** F0000419 - **Notes:** Compatible with MK3 Caleffi Multibloc For optimal performance and safety in your hot water system, choose the Altecnic / Caleffi Relief Valve - Circlip Inlet - F0000419.
