Filling Key for Sime Brava DGT HE Boiler Ref. 6319634
The filling valve for the Sime Brava DGT HE boiler allows water to be replenished in the heating circuit, which helps maintain the proper pressure. If it fails, you will notice that you cannot refill the circuit or that it is leaking water, which can lead to an increase in pressure. This part is compatible with several models from the Sime brand, such as Murelle EV, Format DGT 25 OF, Metropolis DGT 25 BF, DGT 25-OF, and DGT 30-BF, among others. It should be replaced when it shows signs of leakage or does not allow the circuit to be filled.

How to check if ref. 6319634 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 6319634. 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 filling valve 6319634 resolves.
The filling valve allows water to refill the heating circuit. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The pressure of the boiler gradually decreases every day.
Cause: The valve does not seal properly and allows water to flow into the circuit even when it is closed.
Close the valve completely and observe the manometer for several hours with the boiler turned off; if the pressure rises, the valve is not sealing properly.
- 02
Water is leaking in the area of the stem.
Cause: The internal sealing of the stem deteriorates over time.
Dry the area and check if it gets wet again with the valve closed and the boiler cold.
- 03
The key turns with difficulty or gets stuck.
Cause: The limescale in the water accumulates in the mechanism and hinders the rotation.
Try to move it gently in both directions before using a tool to force it.
- 04
The blue cap is damaged or missing.
Cause: It is the most exposed part of the valve and deteriorates first due to use.
Check if the stem rotates normally under the cap before replacing the complete valve.
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.
