Stock · 1 unit

When you open the tap or start the heating, the 3 Bar safety valve Baxi Roca Novanox 24/24F is responsible for releasing water if the circuit pressure exceeds 3 bar. If this valve fails, you will notice that it drips continuously or does not discharge when it should, which can cause problems in the system. This model is compatible with boilers from the Novanox range, as well as with some models from the Platinum, Neobit, Deimos, and Altais ranges. It is recommended to replace it when visible faults or constant leaks are present.

How to check if ref. 125995117 is the part for your boiler

What determines it is not the boiler model, but the reference printed on the part you already have installed.

  1. Find the reference printed on the installed part and check whether it matches the catalogue reference 125995117. If it is not visible, do not identify the part from its shape alone.
  2. Check the full boiler model on its data plate and look for it in the model associations on this page.
  3. Compare the connections and physical body with the original part before installation.
  4. If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Diagnosis and fault codes

Symptoms and faults that the safety valve 125995117 resolves.

The safety valve releases pressure when the circuit exceeds its setting. These are the typical symptoms and what to do:

Common symptoms and faults

  • 01

    Water is continuously dripping from the discharge tube, without the boiler exerting pressure.

    Cause: The internal seat of the valve no longer seals properly and allows water to pass through even though the pressure is within normal limits.

    Check the pressure gauge of the boiler: if the cold pressure is normal and it still drips, the seat is worn out.

  • 02

    The pressure rises significantly when heating the circuit, and the gas valve does not activate.

    Cause: The internal mechanism has seized due to limescale or dirt and does not lift even when the setting is exceeded.

    Manually operate the lever or the bleed cap, if the valve has one, to check if it releases water normally.

  • 03

    Water suddenly comes out of the valve when the boiler has been heating for a while.

    Cause: If the expansion vessel does not properly absorb the expansion of the water, the safety valve performs its function and triggers earlier than expected.

    Before changing the gas valve, check the air pressure of the expansion vessel with the boiler cold and depressurized.

  • 04

    There is a constant water leak that seems to be coming from the body of the gas valve, not from the discharge pipe.

    Cause: The gasket or the body of the gas valve has deteriorated and is leaking, although the opening mechanism is functioning well.

    Dry the area and observe exactly where the water is coming from: the discharge pipe or the valve body itself.
