What it is

The Altecnic 1/2 M/F 10 bar Safety Relief Valve is a pressure relief valve for boiler applications. It forms part of the Altecnic PRVs range. The valve opens at its set pressure to discharge water and protect the system from over-pressure.

Signs this part needs replacing

  • Water continuously weeping or discharging from the valve outlet when system pressure is normal
  • System pressure gauge reading consistently above the 10 bar set point
  • Valve fails to reseat or close fully after relieving pressure
  • Scale, corrosion or debris visible around the valve seat or outlet
  • Boiler losing pressure or requiring frequent top-ups

Before you order

  • Confirm the connection size and gender (1/2 male/female) match the existing valve
  • Check that the required relief pressure rating is 10 bar
  • Confirm compatibility with the Altecnic PRVs range or the boiler model
