The motorised valve is used to control whether hot water from the boiler flows through the radiators or through the cylinder coil. The actuator doesn't provide all that much torque so even if you can move the valve with the manual lever, the actuator may not be able to move it if it is stiff. They are available to click and collect in as little as a minute or have delivered for your convenience. Wouldn't that tee have been better placed in the 22mm section? You can then check whether the spindle of the valve moves freely. the base tends to get stiff causing the motor to burn out i would replace the full valve, With these actuators it's kind of a lightbulb syndrum you'll get one last for years and one that lasts 5 mins so you pays your money and takes your chance IMHO.Bob.

VAT All of which adds up to enhanced comfort for the end-user. Modulating, or AME actuators, are appropriate for precise regulation of the flow as they also have feedback signal and can position themselves very precisely in accordance to the signal from the controller. As others have said, this looks like an S-Plan system with the hot boiler/pump feed on the left, and then splitting into 2 circuits at the tee - with one valve for hot water and the other for central heating. That is, the two with the valves, and the one that feeds them. We still have hot water which I find confusing. endobj My hot water motorised valve sounds like it stays open and the boiler Doesnt stop leaving the hot water scalding.
