How do I know if this 3-way valve is for my boiler?

Verify the reference 140429 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part.

The 3-way valve diverts the water between the heating circuit and the domestic hot water (DHW) circuit.

Does it provide hot water but not heat the radiators (or vice versa)?

Typical symptom that the valve or its motor is not switching; check the actuator motor and ensure the body is not seized.

Which models is it suitable for?

Part shared by various models (see Compatibility). If your model does not appear, send us a photo of the marking and we will confirm it.

Installation and recommendations

Check if you need the motor, the body, or the complete assembly.

What does refurbished mean and what coverage does it have?

Part removed from a boiler out of service, inspected and tested. Includes 1-year warranty and 14-day return policy. Delivery within 2–4 working days in the EU.
