Rated 1 out of 5 by from Limited life of plastic pegs I bought this to replace a failed actuator on an existing Drayton motorised valve. The two springs in the old actuator (which I assume are there to hold the valve in the set position) were both rattling around loose in the casing as the pegs retaining one end of each spring had broken off. These pegs are plastic, moulded as part of the plastic casing, and evidently had grown brittle with age (speeded up by the warm atmosphere next to the hot water tank) and had broken off. Making these pegs from plastic seems to me to be faulty design, and certain to fail in time. Surely they should be steel for a durable design - can't tell if the new one is the same, but it looks identical from the outside. That said, the actuator does what it's supposed to when new, but given its limited durability must score low in all categories. I actually bought the complete valve plus actuator (item 81844), which was cheaper than the actuator alone, and discarded the valve, but this review relates to the actuator alone.

Rated 5 out of 5 by from Excellent Central heating wouldn't change from water to heating, found the problem was the actuator, found one on screwfix at a really good price, fitted it easily by swapping wire for wire, took 10 mins, heating working great now. Very easy to fit to existing fittings

Rated 5 out of 5 by from Quality product & easy install Had an issue with my central heating and hot water where it did whatever it wanted. Even when you turn the heating off and the thermostat down the radiators would stay hot. Had the issue diagnosed by a plumber friend who told me to buy this mid position valve actuator, easy to fit and has fixed my problem. This was over 1 Year ago and all still working as it should!
