Product features：

1. Small fluid resistance, its resistance coefficient is equal to a same length pipe section’s coefficient. 　

2. Structure is simple , small volume and light weight. 　

3. Ball valve is tight and reliable. Now the material of the sealing surface of the ball valve is widely applied in plastics and vacuum system as it has good sealing performance.

4. Simple operation and fast switching.It is convenient to remote control,as it only needs to rotate 90° from fully open to fully closed.

5. The ball valve has the advantages of convenient maintenance, simple structure, renewable sealing ring and easy disassembly and replacement.

6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when the medium passes.

7. It has a wide range of applications, ranging from a few millimeters to a few meters in diameter, and can be used to high vacuum and high pressure.

Installation:

1. Install the valve on the pipe.We can install either end of the valve at the upstream. Handle driven valves can be installed anywhere on the pipeline. However, ball valves with gearbox or pneumatic actuators shall be installed vertically, that is, they shall be installed on horizontal pipes, and the driving device shall be above the pipes.

2. According to the pipeline design requirements,it should install a gasket between the valve flange.

3. It need to be tightened the bolts on the flange symmetrically, successively and evenly

4. Connect pneumatic pineline (when using pneumatic driver)

Check after installation

1. Open and close the ball valve several times by operating the actuator,the ball valve should be flexible and no stagnation,it can verify the ball valve is working properly

2. According to the pipeline design requirements,check the sealing performance of the flange surface between the pipeline and the ball valve
