What it is
The Caleffi 15mm / 1/2 FI x 1/2 6 Bar Safety Relief Valve Grub Screw is a grub screw component for a pressure safety relief valve, manufactured by Altecnic. It forms part of the relief valve assembly on boiler and heating systems, where the valve opens at its set pressure to discharge excess system pressure. The part is listed for use within the Altecnic PRVs range.
Signs this part needs replacing

- The valve fails to reseat and seal after it has opened
- System pressure cannot be held without regular topping up
- Scale or debris found on the valve seat when the assembly is stripped down
- Visible wear or damage to the grub screw on inspection
Before you order
- Confirm the set pressure required matches the 6 bar rating of this valve
- Check the connection sizes on the existing valve against 15mm / 1/2 FI x 1/2
