Product Description

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.
