The valve is widely applied in pipe system of venting and environment project or inlet of fan in building material, metallurgy, coal, mining, glass, light industry and paper industry etc. adjust flow according to different working conditions.
The valve has the features of novel design and compact construction. It adopts multi-blade and multi-axle, which can shunt airflow. Flow resistance and open-close torque is little and operation is reliable. The lubricating bearing of transmission part is easy on operation and regulating with little coefficient of friction. It can control the airflow effectively and make the working system in optimal state by making full use of energy. Valve material choice depends on working temperature.
Manual valve is equipped with worm gear. Pneumatic valve is equipped with pneumatic actuator to receive and feed back switch signal. When add localizer which can receive signal of 4～20mA, it can realize automatic controlling operation. Electric valve is equipped with electric actuator to receive and feed back switch signal. Automatic actuator of automatic valve receives, transmits and adjusts control signal or operating device signal of DCS and PLC meter, which feed back signal of 4～20mA of disc open degree. So customer can adjust open degree according to signal.
