Product Description

Description
Winner DC motorized ball valve consists of on/off type or 3-point type actuator and WSBV… series SS304 ball valve,which have compact structure,stable operation,excellent capacity of water stoppage, large water flow rate, zero dirt block and low torque. 

Application
Winner DC motorized ball valves are widely used in HVAC system, heating system, water treatment system and some industrial equipments. 
 

Operational mode of Motorized Water Valve

Winner motorized ball valve is motor-operated by a type of WRA-42…actuator. The actuator is controlled by 3-point control system and move the ball of the valve, to the opening position dictated by the control signal.
