Product Description

Description
Winner motorized control ball valve consists of WAV4-... series rotary actuator and WCBS...series ball valve. Equal percentage flow characteristic guarantees the valve performances of stability.

Application
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 WAV4-3... actuator. The actuator is controlled by a proportional control system and move the ball of the valve, to the opening position dictated by the control signal.
