## Long description

CALEFFI safety relief valve model 311460 is a 1/2" 6 bar pressure relief valve designed for heating, domestic hot water and plumbing systems. The valve protects closed circuits and vessels from overpressure by opening at the set pressure and discharging excess fluid. Constructed for reliable operation in boiler installations, hot-water cylinders and other pressurised systems, it provides a safety function to prevent damage to equipment and piping.
Advantages
The valve offers precise pressure relief at a 6 bar set point with a compact 1/2" connection suitable for typical residential and light-commercial installations. Its materials and design ensure corrosion resistance and repeatable operation under normal service conditions. The unit is compatible with hot water and heating system media and can be integrated directly into existing pipework with standard fittings.
Suitable for
Domestic and small commercial boilers and heating systems
Hot-water cylinders and storage tanks
Closed plumbing circuits and pressure vessels
Protection of pumps, heat exchangers and pipework from overpressure
Key specifications
Nominal connection size: 1/2" (female thread)
Set pressure: 6 bar
Intended media: water for heating and domestic hot water systems
Function: automatic pressure relief by discharge when set pressure is reached
Typical installation orientation: vertical or as recommended by system designer
How to use
Install the valve in the pressure line or safety port of the boiler, cylinder or closed circuit following applicable local plumbing and heating standards. Ensure piping and connections are clean and compatible with the valve’s thread size, and use appropriate sealing material on threads. The valve must be accessible for inspection and must discharge to a safe drain or pipework that prevents water damage or scalding. After installation, pressurise the system slowly and check for leaks and correct operation at normal working pressure; the valve should remain closed until the system reaches approximately 6 bar.
Usage recommendations
Perform periodic inspection and functional testing in accordance with local regulations and manufacturer guidance. Replace the valve if signs of corrosion, persistent leakage or mechanical failure occur. Use appropriate drain arrangements and check that discharge outlets are unobstructed to ensure safe operation.
