3 Bar Safety Valve Wolf CGB/CGB-K Ref. 2011000
Safety valve set at 3 bar, with a 1/2 inch connection and TÜV certification (code SV·09·946). It protects the boiler circuit by limiting the maximum allowable pressure and bleeding water when exceeded. The brand Wolf appears on the marking, although it is not confirmed as the component's manufacturer. It should be replaced if it continuously drips or does not activate under high pressure.

How to check if ref. 2011000 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 2011000. 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 2011000 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
Water continuously drips from the valve outlet, even with the boiler cold.
Cause: The seat does not seal properly, often due to lime buildup in the internal mechanism.
Measure the static pressure on the manometer with the boiler cold; if it is already around 3 bar, check the filling or the expansion vessel first.
- 02
The pressure rises above normal when heating, and the valve does not trigger.
Cause: The mechanism may be seized due to lack of use, although it could also be because the expansion vessel is not absorbing the water expansion.
Measure the air pressure of the expansion vessel when cold before declaring the valve faulty.
- 03
The circuit gradually loses pressure without any visible leak at any other point.
Cause: The water bled from the valve goes through the discharge pipe and may not leave a visible trace if it goes to a drain.
Follow the discharge pipe to the outlet and look for lime deposits or moisture before searching for the leak elsewhere.
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.
