Description
Winner motorized control ball valve consists of 4N.m WAV4-… series rotary actuator and WCBS… series or W8BV...series ball valve. Equal percentage flow characteristic guarantees the valve performances of stability. Control ball valves are widely used in HVAC system, heating system, water treatment equipment, and water running control in industrial automation, such as: AHU, flesh air-handling unit, differential pressure control unit and heat exchanger for flow regulation and on/off control.
Operational mode
Winner electric control ball valve is motor-operated by a type of WVA4-1…, WAV4-2…, and WAV4-3… actuator. The actuator is controlled by a modulating on/off , 3-point or proportional control system and move the ball of the valve, to the opening position dictated by the control signal.

Function （3-point,or proportional type）
The actuator is controlled by a modulating on/off, 3-point, and proportional control signal, using high transmitting ratio gear drive to fix and lock.
WVA4-1… 230 VAC±15%, 3-point
Brown wire is power on counterclockwise rotation, valve open
Red wire is power on clockwise rotation, valve close
Brown or red wire is power off Valve keep the current position
WVA4-2… 24VAC/DC±15%, 3-point
Brown wire is power on counterclockwise rotation, valve open
Red wire is power on clockwise rotation, valve close
Brown or red wire is power off Valve keep the current position
WVA4-2…-2 12VDC, 3-point
Brown wire is power on counterclockwise rotation, valve open
Red wire is power on clockwise rotation, valve close
Brown or red wire is power off Valve keep the current position
WVA4-3… 24VAC/DC±15%, proportional (0-10VDC/0-20mA, 2-10VDC/4-20mA)
Black wire and brown wire are the power wire.
Yellow wire accept 0-10V control signal to control the valve’s open angle.
WVA4-3…-2 12VDC, proportional (0-10VDC/0-20mA, 2-10VDC/4-20mA)
Black wire and brown wire are the power wire.
Yellow wire accept 0-10V control signal to control the valve’s open angle.

Installation:
1. Ensure that the valve body is in the full open status.
2. Ensure that the actuator is in the fully open position as the follow picture:
3. Aligning the valve stem, press down the aluminum alloy spindle.
Change of running direction
The rotation can be reversed by pushing the CCW/CW switch on the casing.
