Product Details
Description
Winner electric control ball valve consists of WAV4- … series rotary actuator and W CBS … series ball valve. Equal percentage flo w characteristic guarantees the valve performances of stability.
Motorized 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
W inner control ball valve is motor-operated by a type of W AV4-1 … 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.
