Safety valve set at 3 bar, with DN15 connection, for Vaillant boilers from the VM, VMI, VMW, VUI, VUW, VKC, and AquaPlus series, among the indicated compatible models. It releases pressure from the heating circuit when the set limit is exceeded, protecting the heat exchanger from overpressure. It should be replaced when it continuously drips or fails to activate upon reaching the set pressure.

How to check if ref. 190732 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.
- Locate the reference printed on the body of the safety valve you have installed: it should indicate 190732.
- Check your boiler model on the nameplate and look for it in the list of compatible models on this page.
- Compare the connections and the body with the original part before installing.
- If you have any doubts, send us a photo of the screen printing via WhatsApp and we'll confirm it for you before you purchase.
Symptoms and faults resolved by safety valve 190732
The safety valve releases pressure when the circuit exceeds its set point. These are the typical symptoms and what to do:
The valve is continuously leaking through the discharge pipe.
Cause: The seat doesn't close properly, usually due to lime or dirt lodged in the mechanism.
Check the cold pressure of the circuit; if it is already above normal at rest, first inspect the filling and the expansion vessel.
The valve does not activate when the circuit reaches high pressure.
Cause: The mechanism may be seized due to lack of use, leaving the heat exchanger without real protection against overpressure.
Operate the test lever with the boiler cold to check if it bleeds water before replacing it.
The valve activates either well before the pressure reaches high levels or much later than expected.
Cause: If the trip does not match what the pressure gauge indicates, the internal calibration mechanism has lost precision.
Compare the pressure indicated by the manometer at the moment of the trip in several tests before concluding that it has lost calibration.
The circuit loses pressure and no visible leak appears in radiators or pipes.
Cause: The water is being bled through the discharge pipe of the valve, without leaving any visible trace.
Check the outlet of the discharge pipe for any lime deposits or recent moisture before inspecting other areas of the circuit.
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.
