What it is

The Altecnic 312 1/2 3 Bar Safety Relief Valve is a pressure relief valve used on boiler and heating systems. It opens at its 3 bar set pressure to discharge excess pressure and protect the appliance and circuit from over-pressurisation. It carries a 1/2 inch connection and is listed by the manufacturer under the PRV range.

Signs this part needs replacing

  • Water weeping or discharging from the valve outlet when system pressure is below the set pressure
  • System pressure repeatedly dropping with no visible leak elsewhere in the circuit
  • The valve failing to discharge when system pressure rises above 3 bar
  • Corrosion, scale or debris visible around the valve seat or outlet
  • Dripping from the valve after it has operated, indicating the seat no longer seals

Before you order

  • Confirm the connection size on the appliance matches 1/2 inch
  • Confirm the required set pressure for the system is 3 bar
  • Check the valve body and connection type against the existing part on the appliance
  • Verify the appliance is covered by the Altecnic PRV range listing before ordering
