What it is

The Ferroli Safety Valve 39809950 is a pressure relief and safety valve rated at 9 bar, supplied for Ferroli gas boilers. It forms part of the boiler's pressure control arrangement, opening to discharge when the set pressure is reached. It is listed under the manufacturer part number 39809950.

Signs this part needs replacing

  • Water weeping or discharging continuously from the valve outlet when the system is below its set pressure.
  • Pressure gauge reading climbing above the normal operating range, or repeated discharge during heating cycles.
  • Scale, corrosion or debris visible around the valve seat or outlet.
  • The valve fails to reseat after a pressure event, leaving a persistent drip.
  • System pressure dropping and requiring frequent topping up with no other visible leak.

Before you order

  • Confirm the valve rating required for the appliance against the rating stated in this product name.
  • Check the boiler model and product code against the fitment list above before ordering.
  • Inspect the valve location and connection arrangement on the appliance to confirm the fitting matches.
  • Have the boiler isolated, drained and depressurised before removal of the old valve.
