What it is
The Caleffi 309473 is a CST temperature and pressure relief valve from the Series 309 range, with a 1/2" connection and a 7 bar relief setting. It is a safety valve that opens to discharge water when the temperature or pressure in the system reaches its set limits. It sits within the pressure relief and safety valve category.
Before you order
- Confirm the system port is 1/2" so the valve connects correctly.
- Check that a 7 bar relief setting suits the design pressure of the appliance or system it protects.
- Match the part number 309473 and Series 309 against the valve being replaced.
- Confirm that a combined temperature and pressure relief function is what the installation requires.
