Altecnic / Caleffi Pressure Relief Valve with Circlip Connection 4.5 Bar - F0000477

Altecnic / Caleffi Pressure Relief Valve with Circlip Connection 4.5 Bar - F0000477

The Altecnic / Caleffi Relief Valve - Circlip Inlet - F0000477 is a vital component for domestic hot water systems. Designed to protect hot water cylinders and heating systems, this valve ensures the safety of boilers and related components. It is specifically chosen based on the required set pressure. When the pressure increases and reaches the predetermined discharge pressure, the valve automatically opens, releasing excess pressure into the atmosphere. This function helps to prevent potentially dangerous pressure levels within the system, thereby safeguarding both the boiler and the hot water storage cylinder, as well as ensuring the safety of nearby personnel.

**Product Specifications**

  • **Materials:** Brass
  • **Set Pressure:** 4.5 Barg
  • **Product Code:** F0000477
  • **Notes:** Compatible with MK3 Caleffi Multibloc

Improve the safety of your domestic water system with the Altecnic / Caleffi Relief Valve, providing dependable performance and peace of mind.
