Winner fast running electric actuator control ball valve consists of WRA3-...S series stepping motor actuator and W8BV... series brass ball valve.
Equal percentage flow characteristic guarantees the valve performances of stability. Stepping motor control ball valve. The characteristic of
it is accurate、fast、strong anti-interference. It is a typical digital control mode.

They 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. 

Features

• 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.
