What it is

The Ariston 65155493 is a safety valve rated at 10 bar, manufactured by Ariston for use in its heating appliances. It forms part of the pressure relief arrangement, opening to discharge when system pressure reaches the valve's set rating. It is listed for the Ariston NEXT 14 SFT NG UK appliance.

Signs this part needs replacing

  • Water weeping or discharging from the valve outlet when the system is below its set pressure
  • The valve failing to open when system pressure rises above the rated 10 bar
  • Scale or debris holding the valve seat open, causing a constant drip
  • Visible corrosion or damage to the valve body or seating face
  • Repeated discharge during normal heating cycles, indicating the valve no longer holds its rating

Before you order

  • Confirm the appliance model matches the fitment listed above
  • Check the pressure rating marked on the existing valve against the 10 bar rating of this part
  • Inspect the valve connection and seating arrangement before removal to confirm like-for-like fit
  • Verify the system pressure and expansion vessel operation, as discharge can also indicate a fault elsewhere
