Designed for V4043 Series three port motorised valves, this replacement powerhead is suitable for field replacement of heads in diverting and straight through valves with no need to drain the system. A head which does not require the system to be drained is identified by a small round bump on the cover and a 6 or higher OS suffix number. Only two screws and two locating pegs are used to connect heads to the body.
