Description
DC motorized ball valve consists of on/off type or 3-point type actuator and W8BV… series ball valve,which have compact structure,stable operation,excellent capacity of water stoppage, large water flow rate, zero dirt block and low torque. DC motorized ball valves are widely used in HVAC system, heating system, water treatment system and some industrial equipment.
Function (3-point or on/off type)
The actuator is controlled by a modulating on/off or 3-point control signal, using reversible synchronous motor and gear speed reducer drive to fix and lock.
WRA-42… 3-point type
Brown wire is power on Valve open
Black wire is power on Valve close
Brown or black wire is power off Valve keep the current position
Blue wire is connected to the null wire.
Also can be used as on/off type.
WRA-42…A on/off type
Blue wire is the control wire. Power on: valve open, power off: valve close
Black wire is connected to the com.
Brown wire is connected to the power wire.
Only can be used as on/off type.

Application
HVAC system, heating system, Water treatment system, Industrial equipment.
Operational mode
Winner DC motorized ball valve is motor-operated by a type of WRA-42…, and WRA-42…A actuator. The actuator is controlled by a modulating on/off or 3-point control system and move the ball of the valve, to the opening position dictated by the control signal.
