Winner stepping motor electric actuator control ball valve consists of WRA3-...S series stepping motor actuator and WsBV... series brass ball valve.
Equal percentage flow characteristic guarantees the valve performances of stability. The characteristic of it is accurate、fast、strong anti-interference.
It is a typical digital control mode.
Application
HVAC system, heating system, water treatment equipment, and water running control in industrial automation.
Stepper motor drive
Adjustable resistance is the internal detector, which can detect the running position during the whole operational process.
Closed loop control mode. Control accuracy is 3%.
Position limitation protection and overload protection.
