Description of Motorized Water Valve
EO 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. EO motorized ball valves are widely used in HVAC system, heating system, water treatment system and some industrial equipment.
Application of Motorized Water Valve
HVAC system, heating system, Water treatment system, Industrial equipment
Operational mode of Motorized Water Valve
EO motorized ball valve is motor-operated by a type of WRA-63…, and WRA-63…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.

Actuator
WRA-63… AC230/110/24V, 50/60Hz, 3-point
WRA-63…A AC230/110/24V, 50/60Hz, on/off
Output torque: >3.5N.m Angle of rotation: 90°
Protect rank: IP55/IP54 On/off time: 16S
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-63… 3-point type
Black wire is power on Valve closed
Brown wire is power on Valve open
Black or brown 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-63…A on/off type
Black wire is the control wire. Power on: valve open, power off: valve close
Brown wire is connected to the power wire.
Blue wire is connected to the com. Only can be used as on/off type.
Installation
insert the valve stem to the bottom of the actuator, and insert 2 pin, located in the bottom of the actuator to the valve’s mounting hole. Then screw down the brass cap nut
