Description
control ball valve consists of WAV4-… series rotary actuator and WCBS… 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
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.

Actuator
WVA4-2… 24VAC/DC±15%,3-point
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.
WVA4-2… 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
