I've had one of my two Drayton Za5 valves micro switches stick on me yet again, this time resulting in the HW permanently stuck on. I'm pretty sure it's this because if I hit it with a hammer it goes off for a while! And I have 4 of these over the years fail with similar faults.
My question is can the actuator be replaced with a different more reliable model without changing the valve itself?
I know it's not expensive or difficult to swap the head but I'm tired of repeatedly swapping these every couple of years!
