What it is

The Caleffi 309400 is a temperature and pressure relief valve from the Caleffi 309 Series. It is a combined safety valve that relieves excess temperature and pressure from a hot water system through a single valve body. The valve has a 1/2" connection and is rated at 10 bar.

Before you order

  • Confirm the 1/2" connection matches the tapping on the installation.
  • Check that the 10 bar rating suits the design pressure of the system.
  • Verify the part number 309400 and the 309 Series designation against the valve being replaced.
  • Confirm the CST variant is the correct configuration for the installation.
