Honeywell Gas Valve V7335A For Chaffoteaux MX2 24 FF - Ref. 61312123
Gas valve with modulating pressure regulator Honeywell V7335A (Modureg series), identified on the label itself. The reference 61312123 corresponds to the gas valve of the Chaffoteaux MX2 24 FF and MX2 30 FF boilers, according to two independent sources. It regulates the gas pressure to the burner. It is replaced when the boiler does not ignite or modulates the flame poorly.

How to check if the ref. 61312123 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.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 61312123. If it is not visible, do not identify the part from its shape alone.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms and faults that the gas valve 61312123 resolves
The gas valve regulates and modulates the gas flow to the burner. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler does not ignite or gets blocked when starting the burner.
Cause: The pressure regulator of the gas valve does not allow the necessary gas flow to initiate combustion.
Check that the gas supply pressure from the network or the bottle is the usual one for the installation before replacing the gas valve.
- 02
The flame suddenly increases or goes out for no apparent reason.
Cause: The regulator does not adjust the output pressure properly according to the power demand.
Check that the temperature sensor or the PCB is not requesting sudden changes in power, as this also causes an unstable flame.
- 03
There are ignition faults that come and go; sometimes it ignites well and other times it doesn't.
Cause: A variation in the gas pressure reaching the valve causes the regulator not to always reach the correct opening point.
Check the gas pressure at different times of the day before assuming that the gas valve always fails the same way.
Fault codes Chaffoteaux that this part resolves
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 70-80 | No flame detection | If the Honeywell gas valve 61312123 does not open or its solenoid/modulation fails during the ignition attempt, gas does not reach the burner and the boiler enters "No flame detection". Check the voltage to the valve during the attempt and input/output pressures with a manometer; if there is voltage and no flow/pressure, the valve is faulty. |
These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.
