Hi
I have a faulty Siemens DVA3 3 Port Mid Position Actuator that needs replacing, Can get a Drayton MA1 quite cheap, will this fit in place of the Siemens ! .
I am wanting to replace a Siemens DVA3 Actuator ( Mid Position ) have found one on ebay (Used) but says they changed it , but turned out they had to change the whole Valve unit, now on the one they have t says on the label BPZVA3 , mine only says DVA3 , what does the BPZ: mean !.
