SIT Gas Valve 0845070 For Beretta Kompakt 24 CSI
SIT gas valve, code 0845070, for Beretta boilers from the Amica, Ciao, City, Junior, Kompakt, and Super Kompakt 24 CSI ranges. It regulates gas entry with two solenoid valves (EV1 class B, EV2 class J) and a modulator that adjusts the flame. It is replaced when the boiler does not ignite, clicks without a flame, or modulates unstably. Manufacturer and code taken from another photo of the same physical part.

How to check if ref. 20007784 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 20007784. If it is not visible, do not identify the part by 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 20007784 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 burner clicks when trying to ignite but the flame doesn't light.
Cause: One of the solenoid valves EV1/EV2 does not open the gas flow in time even though it receives the ignition command.
Note that both coils receive current at the moment of startup before the valve is deemed faulty.
- 02
The flame fluctuates, rising and falling without any apparent reason.
Cause: The modulator does not consistently regulate the amount of gas reaching the burner.
Check the gas pressure of the installation; irregular pressure can simulate a fault in the modulator.
- 03
The boiler locks out several times a day and needs to be reset manually.
Cause: The repeated cut due to EV1/EV2 opening failure triggers the safety of the control unit.
Also check the condition of the flame detection electrode: a poor contact there causes similar lockouts.
Fault codes for Beretta that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| A01 | Lockout due to absence of flame (ignition failure after several attempts). | The gas valve 20007784 may not open/modulate and does not allow gas to pass to the burner. Check by applying voltage to the coil/modulator and measuring downstream pressure during ignition; if there is power but no flow/ionisation, the valve is defective. |
| A11 | False flame (parasitic flame) detected with the burner theoretically off. | The gas valve may not close completely and allows residual gas to pass, maintaining a flame. Check for the absence of voltage at the valve and perform a tightness/pressure drop test on the ramp after closing; if the flame signal persists without power to the valve, replace it. |
| A20 | The flame takes a long time to extinguish after the gas valve is closed. | Slow closing/internal leak of the gas valve. Check that, upon removing power, the pressure in the ramp drops and the flame extinguishes in <10 s; if this does not occur, the valve is stuck or leaking and must be replaced. |
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.
