Penglai Huande Steel Valve Co., Ltd can supply pneumatic ball valves for our customers. It is known that pneumatic ball valves are ball valves with pneumatic actuators. Pneumatic actuators perform relatively quickly, with the fastest switching speed of 0.05 seconds/time, so they are often called pneumatic quick-cut ball valves. Pneumatic ball valves are usually equipped with various accessories, such as solenoid valves, gas supply processing triplets, limit switches, positioners, control boxes, etc., to achieve local control and remote centralized control, in the control room can control the valve switch , do not need to go to the scene or bring manual control at high altitude and danger, to a large extent, saving manpower resources and time and safety.

The ball of the pneumatic ball valve is floating. Under the effect of medium pressure, the ball can generate a certain displacement and press on the sealing surface of the outlet end to ensure that the outlet end is sealed.

The structure of the floating pneumatic ball valve is simple and the sealing is good. However, the load of the ball bearing the working medium is all transmitted to the outlet sealing ring. Therefore, it is necessary to consider whether the sealing ring material can withstand the working load of the ball medium. This structure is widely used in low and medium pressure ball valves.

The use and maintenance of Pneumatic Ball Valve:

Minding: This manual applies to electric (or pneumatic) ball valves with flanged ends:
  • Remove the protective caps on both sides of the flange and rinse it with the valve fully open.
  • Before the installation, the whole machine should be tested according to the specified signal (electricity or gas) (to prevent the use of performance due to vibration caused by transportation), and it can be installed on-line only after being qualified (wiring according to the circuit diagram of the electric actuator).
  • Before preparing to connect with the pipeline, the remaining impurities in the clean pipeline must be flushed and removed (these materials may damage the valve seat and the ball).
  • During the installation, please do not use the actuator part of the valve as lifting point to avoid damage to the actuator and accessories.
  • The pipe near the installation point should not have the phenomenon of dangling or receiving external force. Pipeline supports or supports can be used to eliminate the deviation of the pipeline.
  • After connecting with the pipe, please cross-lock the flange connecting bolt with the specified torque.
