What it is

A 1/2 inch female-to-female safety relief valve manufactured by Altecnic and set to open at 5 bar. It is installed on boiler installations to discharge excess pressure and protect the appliance and its pipework from overpressure.

Signs this part needs replacing

  • Water dripping or discharging from the valve outlet when system pressure is normal
  • System pressure climbing above the set point, with the gauge reading rising steadily
  • Valve failing to reseat after venting, leaving a persistent drip
  • Scale or debris visible at the valve seat or outlet

Before you order

  • Confirm the connection size and thread match the valve being replaced — 1/2 inch female at both ends
  • Check that a 5 bar set pressure matches the system design pressure and the existing valve rating
  • Confirm the discharge pipework is correctly routed and clear before fitting
