Drayton MA1 Actuator For 3 Port Valve Mid 27651

Drayton MA1 Mid-Position 3-port actuator switch 230V / 50Hz [part number: 27651] is a direct replacement for the British Gas Blue BGMVSP-23 [also known by some as the British Gas MA1], Drayton MA1-6793, and the MA1-7793. This is a motorised valve that has 5 wires. It has 3 methods of operation. Those are heating, hot water, or both heating and hot water together. It’s extremely easy to fit, has “snap-on” actuators, and is very easy to wire. Anyone with basic wiring skills should be fine performing the replacement. Just remove the old actuator and fit the new one. Job done. However, if in doubt, leave it to a professional. Shouldn’t take them longer than 5 – 10 minutes to remove the old valve and replace it with the new one.

Some very common symptoms / problems that can be the result of a faulty actuator that needs replacing are as follows. Boiler won’t start up / heating will fail to come on. A slow transition between changing positions. A noisy actuator may indicate that the motor inside has failed or is failing. If the actuator switch is grounded / stuck in one position permanently and won’t respond at all, other than the motor, this could probably be a failed / faulty switch mechanism, and the unit more than likely needs replacing.
