The Divatech/Domina filling valve with retention is a safety valve that releases water when the circuit pressure exceeds the limit, usually around 3 bar. If this part fails, you will notice a continuous drip or that it does not discharge when it should. This valve is compatible with boilers from the Cointra range, such as the Excellent micro LN 24 E, and Ferroli, including models like the Domicompact F24 and Divatech F32, among others.

How to check if ref. 36901470 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 36901470. 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 safety valve 36901470 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
The heating circuit needs to be refilled very often, almost every week.
Cause: The valve does not close properly and the pressure is slowly leaking out.
Check the expansion vessel and the radiator seals before blaming the valve.
- 02
When opening a hot water tap in the house, a change in the heating pressure is noticeable, or vice versa.
Cause: The valve does not hold water and the circuits are interconnected.
Close the valve completely and check if the heating pressure changes when opening the domestic hot water.
- 03
Water is leaking from the body or the lever.
Cause: The valve loses tightness with use.
Tighten the threaded connections first before replacing the complete valve.
- 04
When trying to fill the circuit, it seems that the water flows towards the network instead of entering the boiler.
Cause: The anti-return retention function is failing and the flow is behaving in reverse.
Check that the key is installed in the direction of the engraved arrow.
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.
