Description
Winner control ball valve consists of WAV4-… series rotary actuator and WCBS… series ball valve, size could be matching from 1/2'' to 2''. 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.
Application
HVAC system Heating system Water treatment system Industrial equipments Heat pumps
Operational mode
Winner modulating control ball valve is motor-operated by WAV4-3… actuator. The actuator is controlled by a modulating proportional control system and move the ball core inside of the valve, to opening valve or closing by the control signal 4-20mA (this is acurrent range, you could select a value from this range to determine how much valve angle opening)

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.
