Mini 12vdc dc motor operated irrigation 2-way or 3-way electric control ball valve
Mini 12vdc dc motor operated irrigation 2-way or 3-way electric control ball valve
Description
Winner DC motorized ball valve consists of on/off type or 3-point type actuator and W8BV… 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 DC motorized ball valves are widely used in HVAC system, heating system, water treatment system and some industrial equipment.
Application
HVAC system, heating system, Water treatment system, Industrial equipment.
Operational mode
Winner DC motorized ball valve is motor-operated by a type of WRA-42…, and WRA-42…A actuator. The actuator is controlled by a modulating on/off or 3-point control system and move the ball of the valve, to the opening position dictated by the control signal.
