Motorised valve - How can I control it manually?

Re: How to control motorised valve?

The boiler is working perfectly but I want to turn off the rads until I get the valve replaced.

Unfortunately there isn't an actuator! Some one must have thrown it away. I want to turn off the rads in the meantime.

In that case turn the boiler on, wait for pipe to get warm and see which way it goes, spin until you get it going to hot water only or do what diamondgas has said. But if it's the valve thats goosed rather than the head it may not work. i.e. might not be able to shut off rads. Have you an immersion?, if you have turn boiler off and use immersion until fixed.

It's listed under Baxi spares 3 PORT VALVE BODY MPE322 but unfortunately no longer available.

Not an exact science but the flat part of the 'D' will either point towards the pipe you want closed or will be 45deg to it! I'm raking brains here so may be way out coz uzually you have both parts......... AND it's been some time since I've seen this kind of valve... :skep:

Thanks for the suggestion. At least I have something to work with - out of 8 possibilities. I didn't think it would be a smaller angle than 45 degrees!

Thanks, Simon!

I'd turn the boiler on and then experiment with feeling the pipework to see which pipe gets hot when you move the position of the valve. The pipe going to the cylinder will be your hot water and the other will be your heating.

Using the valve manually will mean you will have no control over how hot your water gets. This could lead to pumping over issues or worse. You really need to get a new actuator and get it wired in.
