Pneumatic Actuator Control Plug Valve

The pneumatic plug valve only needs to use the pneumatic actuator to rotate 90 degrees with the air source, and the rotating torque can be closed tightly. The chamber of the valve body is completely equal, providing a direct flow path with almost no resistance to the medium. In general, the plug valve is most suitable for direct opening and closing. The main feature of the ball valve is compact structure, easy operation and maintenance, suitable for water, solvents, acids and natural gas and other common working media, but also suitable for oxygen, hydrogen peroxide, methane and ethylene and other poor working conditions of the media. The valve body of the plug valve can be integrated or combined. The pneumatic plug valve works by rotating the spool to open or close the valve. Pneumatic plug valve switch light, small size, large diameter, reliable sealing, simple structure, easy maintenance. The sealing surface and the plug surface are always closed and are not easily eroded by the medium. Has been widely used in various industries. Pneumatic ball valve and plug valve belong to the same type of valve, but its closing part is a sphere, the sphere rotates around the center line of the valve body to achieve opening and closing.

1. The fluid resistance is small, and its resistance coefficient is equal to the pipe segment of the same length. 2. Simple structure, small size, light weight. 3. Tight and reliable. The sealing surface material of plug valve is widely used in polytetrafluoroethylene and metal, which has good sealing performance and has been widely used in vacuum system. 4. Easy operation, fast opening and closing, only 90° rotation from full opening to full closing, convenient remote control. 5. Easy maintenance, pneumatic ball valve structure is simple, the general sealing ring can be removed, disassembly and replacement is convenient. 6. When the valve is fully opened or fully closed, the sealing surface of the plug and seat is isolated from the medium, and the medium will not cause the erosion of the sealing surface of the valve.

During the opening and closing process of the forged steel globe valve, because the friction between the disc and the sealing surface of the valve body is smaller than that of the gate valve, it is wear-resistant. The opening or closing stroke of the valve stem is relatively short, and it has a very reliable cut-off function, and because the change of the valve seat port is proportional to the stroke of the valve disc, it is very suitable for the adjustment of the flow rate. Therefore, this type of valve is very suitable for cut-off or regulation and throttling.
