Box Contains 1 x 22mm 2 Port Valve Review: Works like a dream! - After our boiler heating and hot water system service provider tried twice to fix the pump running problem when heating and hot water switched off without success (first visit i as told it was a faulty pump, second visit i was told it was the hot water cylinder thermostat) I decided that I may as well work out the problem myself. After reading reviews here on desertcart and also via plumber Google, I fund others mentioning the same symptoms for their system for the same boiler as mine and it was dead right, basically the heating valve actuator microswitch had failed when the airing cupboard had become warm (eg after 5 hours of heating.) This was a direct replacement unit and works a dream. Why the service company, a BIG Well known one, didn’t think of this is beyond me. Anyway, all done, great it’s, good price, speedy same day Prime delivery, job done! Review: Simple to do but be safe.. really happy with the result - I have a few of these installed to zone off an extension and to trigger circulation to a pressurised water cylinder. Recently the hot water valve actuator wasn’t closing when demand ended. This means the pump runs endlessly and hot water is forever produced based on thermostat demand. It always returned when given a little jiggle but obviously not a practical solution. So.. with these units the head is easily replaceable. This came with the 2 port as well but was a good price compared to regular retail outlets. Wiring was super simple assuming appropriate skills. I’m handy but definitely not an electrician. For me this was simply replacing wiring like for like (see pic). BUT ISOLATE THE SUPPLY FIRST AND CHECK!!! All done in about 20 minutes. First time for me too. Once tested a few times really happy that compared to a plumber call out this was a simply job at low cost!

The 27650 is the ZA5 actuator only. Rather oddly, whilst I only needed the actuator, it was cheaper to buy the 27100 and throw away the valve! **Q: Does the drayton ma1 valve head interchange with british gas valve bgmsvp-23 valve?** A: From the information I can find on the internet the British Gas BGMVSP-23 valve is made by Drayton and is equivalent to their MA1 so an MA1 actuator head should work with the BGMVSP-23 valve body but I do not have personal experience of this 3-port valve, only the 2-port version. Depending on the issue and the age of the valve body on your heating system it may be worth thinking of changing the complete valve and actuator. Often it is much cheaper to buy the complete valve and actuator than just the actuator which is often 3 times the price of buying the complete unit. **Q: Is this valve normally closed or open** A: The valve is normally closed. The motor opens it and the return spring closes it. **Q: Can you confirm if this is a Drayton ZA5 actuator? I can't tell from the photo as it isn't very sharp.** A: This is the "complete" Drayton ZA5 motorised valve - the 2 port valve complete with actuator. I purchased as it was cheeper to buy this than the individual "actuator". A case of manufacturer claiming that actuator is available separately and then selling it as a spare for an excessive price. Easy to fit plus I now have a spare valve as well! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works like a dream! *by L***S on 11 May 2019* After our boiler heating and hot water system service provider tried twice to fix the pump running problem when heating and hot water switched off without success (first visit i as told it was a faulty pump, second visit i was told it was the hot water cylinder thermostat) I decided that I may as well work out the problem myself.

Boom ### ⭐⭐⭐⭐ Easy to fit *by P***Y on 6 May 2024* I didn't need to replace the valve part but it's cheaper to buy the whole gubbins rather than just the actuator which is what broke. These things are not the most reliable, but they are easy to fit and replace. The old one packed up because the post to which one of the return springs attach snapped off - poor design I think. They are, however, very easy to fit provided you isolate the electrics and carefully replicate the original wiring in the junction box. I'm not a tradesman so I wouldn't like to wire one in from scratch. Time to fit once diagnosed, about 30 minutes max. The new actuator just clips on to the existing valve. ## Frequently Bought Together - Drayton 27100 22mm 2 Port Motorised Valve - REGE105 REGIN 5 Way Plug/Socket with Strain Relief --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/48670487-drayton-27100-22mm-2-port-motorized-valve](https://www.desertcart.co.uk/products/48670487-drayton-27100-22mm-2-port-motorized-valve) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-14*
