Product Description

Description 
Winner WRA3-...(D) series electric DC control ball valve consists of on/off type or 3-point type DC actuator and W8… series ball valve，which have compact structure，stable operation，excellent capacity of water stoppage, large water flow rate, zero dirt block and low torque.
 
Winner motorized ball valves are widely used in HVAC system, heating system, water treatment system and some industrial equipment.
                 
Operational mode
Winner motorized ball valve is motor-operated by a type of WRA3-…D actuator. The actuator is controlled by a modulating on/off control system and move the ball of the valve, to the opening position dictated by the control signal…
