How do I know if this is the gas valve for my boiler?
Verify reference 252457 and ensure your model is on the list of compatible ones; compare the body, the actuator motor, and the connections with the original. It is a Vaillant part.
What is the purpose of the 3-way valve?
It diverts the water between the heating circuit and the domestic hot water (DHW) circuit. When you open a hot water tap, it switches to prioritise DHW and stops sending water to the radiators.
The boiler provides hot water but does not heat the radiators (or vice versa), is it the valve?
It is a typical symptom: the valve or its motor do not switch. It is also common for the radiators to heat up when the DHW tap is opened. Check the actuator motor and ensure the body is not seized or calcified.
Which models is it suitable for?
Part shared by various models (see Compatibility). If your model does not appear, send us a photo and we will confirm it.
Is it the motor, the body, or the assembly?
Check if you need just the actuator motor, only the body, or the complete assembly; compare it with your original part before installing. This is Vaillant.
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.
