How to check if ref. R2907 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 R2907. 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.

Symptoms and faults that the R2907 safety valve 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

  When operating the bleed lever, the valve releases water and does not close properly.

  Cause: A dirt particle may be trapped in the seat, preventing proper closure.

  Repeat the lever opening and closing several times carefully before considering the valve defective.

• 02

  There are limescale stains or dry white residues around the gas valve and under the boiler.

  Cause: Previous leaks indicate that they have dried up, suggesting that the gas valve has not been closing completely for some time.

  Check if the stains coincide with times of higher heating demand before assuming that the part is broken.

• 03

  Before the valve discharges water, the pressure gauge shows a higher than usual pressure.

  Cause: It is the normal reaction of the valve when the circuit exceeds its set point, regardless of the cause of the increase.

  Check the cold pressure with the boiler's pressure gauge before assuming the valve is faulty.

• 04

  The valve drips after filling or bleeding the circuit.

  Cause: If the filling increases the pressure of the system, when the boiler heats up, the setting is exceeded and the valve operates, even if it is in good condition.

  Check the cold pressure after filling and adjust it to the range indicated by the boiler before suspecting the gas valve.
