We are glad to share with you about the results of our work, company news,and give you timely developments and personnel appointment and removal conditions.
  • Operating torque The operating torque is the most important parameter for selecting an electric actuator. The output torque of the electric device should be 1.2 to 1.5 times the maximum torque of the valve.


  • Electric gate valves have irreplaceable roles and important applications in many aspects. Using electricity as energy support can better improve work efficiency, without pollution, and it is an environmentally friendly energy method. Let's take a look at the structural characteristics of the electric gate valve.


  • The valve electric device is one of the devices for operating the valve and connecting the valves. The device is powered by electrical power and its motion can be controlled by the magnitude of the stroke, torque or axial thrust. Due to the working characteristics and utilization of the valve electric device, it depends on the type of valve, the working specifications of the device and the position of the valve on the pipeline or equipment. Therefore, it is important to grasp the correct choice of the valve electric device; considering the prevention of overload (working torque is higher than the control torque) becomes a crucial part.


  • Valve World Expo will once again take place in conjunction with the Valve World Conference in Düsseldorf in 2018.


  • How to choose the appropriate actuator type for different valves? From the perspective of electric actuator sales, the selection of valve electric actuators is mainly based on the parameters brought by customers.


  • On the contrary, when the compressed air enters the two ends of the pneumatic actuator from the B nozzle, the gas pushes the double plug to move straight to the middle, the rack on the piston drives the gear on the rotating shaft to rotate 90 degrees clockwise, and the valve is closed. At this time, the gas in the middle of the pneumatic actuator is discharged with the A nozzle.
