Rated 3 out of 5 by Electrics a bit unreliable Well made 3-port valve, easy to fit, easy to change the actuator head. But the actuator head suffers from weak electrics, which are prone to failure. Like other reviewers, I have had to change the head twice within a few years simply because of failure of the controlling electrics. 15 Apr 2016
Rated 5 out of 5 by Good delivery Part changed Delivery next day and part changed easily Metalic part faulty so left electrical part in situ Good to split two parts easily 26 Dec 2015
Rated 5 out of 5 by 3 port valve At this price you can't go wrong, the complete unit is cheaper than the head alone which is identical. My only gripe is the valve body is a fraction of the weight of the original I replaced. The threads and back nuts are identical so you don't need to change them on a like for like replacement. 24 Dec 2015
Rated 5 out of 5 by Drayton MA1 Got this to replace existing unit as electrical part failed. This unit only seems to last 2 years before something goes wrong with the electrics. Very good when working but at a mid position switch does the job but beware I have this unit on my boiler heating system 15 years and have fitted about 5 in that time. Otherwise a good unit 15 Dec 2015

Answer: 
The MA1 is a direct replacement for this valve and actuator. It will require a drain down and change out of both parts as the MA1 actuator will not fit onto the 679H valve body.The valve body is however the exact physical size it is the actuator couplings that are different.

BGMVSP-23

Hi
I am looking for a replacement for mid position actuator BGMVSP-23, I believe that I would need to get replaced the electric component and/or valve. I had an electrician who advised that the electric part is fine however the valve is stuck. Please advise which Drayton product would be a direct replacement for the following:
- electric part
- bras valve
- electric part and the valve combined

Answer: 
The BGMVSP23 is a British Gas mid position variant.

It can be replaced by the Drayton Mid Position Actuator part No 40818 which will attach to the existing valve body or the whole valve and actuator assembly part No 81844

Answer: 
This is a direct replacement for the Danfoss HSA3 mid position valve. Both valve and actuator would be required to be changed.

There is a slight difference between the existing wiring and the new wiring of the MA1. On the HSA3 the BROWN wire will become the WHITE wire. All other wires are the same.

Answer: 
The A679B316-52LO was designed for Worcester. It was supplied to Worcester for the type of boilers that they were making at that time and is only available from Worcester. It is a 3/4" 3 wire, 3 port diverter valve with inverted threads. I am afraid that Drayton do not have a substitute for these valves as they were manufactured as a special for Worcester only.
