The valve is the new type energy saving high efficient product designed on the base of introducing technology of Japan. It is widely used at venting pipe and air-blower inlet in building material, glass, mining, power, light industry and papermaking departments. It adjusts flow in pipe by the different working conditions.
The valve has the features of novel design and compact structure. Its regulating disc 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 flexible on operation and handy of 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. It is the ideal airflow-regulating device in piping system.
