Q: Hi, I have a Honeywell 28MM zone valve that has failed, although I can manually operate. It was installed in 1985. If I drain down, will this kit replace the current actuator ? Rgds.

A: Please let us know the model number of the zone valve you currently have, and we can advise.
Q: Hi does this kit fit both the 22mm and the28mm valves and are instructions provided as to how line up the valve spindle with the actuator/power head Similarly does the 40003916 -003 power head fit both the 22mm and 28mm valve thanks

A: Yes both this and the 40003916-003 will fit any size V4073A valve. Instructions are included with the 40003916-003.
Q: Would this kit replace the innards of my Potterton MSV322? The valve is working but only partially shuts off flow to the unrequired outlet. The spindle is not too stiff but can be rotated 360 degrees. Thanks

A: No, I'm afraid it only fits Honeywell valves. Potterton do not offer a similar kit, so it will need to be a complete valve change.

The Honeywell 40003918-007 has two uses:

1) As a conversion kit to use a new 40003916-003 replacement powerhead on an old style (pre 1986) V4073 motorised valve.
A motorised valve that does not require this kit can be identified by a bump on the top of the powerhead.

2) Used to replace the innards on new style V4073A valve bodies. For example where the valve body is sticking or seized.

Good product, delivered rapidly, simple to install, worked first time
The part I required was ex-stock and at a good price. My first transaction with Heating Controls On Line was 11 years ago and once again they did a super job.
Easy to identify the part, notified of despatch and delivery details, part arrived punctually and in good condition
