What it is
The 1/2 M/F 4 bar Safety Relief Valve is an Altecnic component used in boiler and pressure relief applications. It forms part of the Altecnic PRV range and opens at a set pressure of 4 bar to discharge excess pressure and protect the system from over-pressurisation.
Signs this part needs replacing
- Water weeping or discharging from the valve outlet when system pressure is below the set pressure
- The valve fails to reseat and continues to pass water after relieving pressure
- System pressure rises above the 4 bar setting without any discharge
- Visible scale, corrosion or debris around the valve seat or outlet
- Boiler pressure gauge reads persistently high despite normal operation
Before you order
- Confirm the connection size is 1/2 inch male/female to match the existing installation
- Check that a 4 bar set pressure is correct for the system
- Confirm compatibility with the Altecnic PRV range
- Verify the valve type and application match the boiler setup
