Q: I have an ACL Lifestyle 2 port 779H335 30L10. It sticks sometimes and needs freed using the lever. It is 25 years old and probably needs replaced. The Drayton ZA6/779-2 seems to be the direct replacement BUT it has a clip on facility. My one doesn't. Does that mean that the new head would not fit the old body (and thus need a system drain down) please?

A: That's correct. You would need to change the body was well. However the dimensions and thread are the same - so no pipework alterations are needed.
Q: Has this replacement valve got 6 wires please

A: Yes it has.
Q: There is no direction arrow on the valve so can I take it that it flows into port A which has a smaller bore, Many thanks, Samuel Mc Dermott

A: That's correct.
Q: Confused by this: Drayton motorised valves now feature removable actuators which simplify installation and future servicing. No tools are required to fit the actuator to the body as it simply clicks into place. So can I replace mine without draining the system? I.e straight swap the grey box, no need for pipe strangling?

A: If you have the old "lifestyle" model then no, you will need to replace the whole valve. If you have the newer ZA6 model, then you can replace just the actuator (grey box).
Q: does this valve come with the internal nuts and olives as it is in the picture

A: Yes it does.
Q: does this include both the actuator and the valve itself

A: Yes it does.
Q: I need to replace an existing Drayton 28mm actuator valve (BGMVSP 9). Is this valve a straight swap, if not do you supply the required part? Many thanks.

A: As long as the valve body it 28mm, then it will be a straight swap.
Q: Does this actuator fit the old lifestyle 779h335 body or do you need to change the whole valve?

A: No, you will need to replace the whole valve. The old Lifestyle valves had a non-replaceable head.
