Q347F-150LB Stainless Steel Fixed Ball A105 Ball Valve Turbine Ball Valve Manual Cemented Carbide Seal Factory

Purpose and functions:

• The fluid resistance is small, and its resistance coefficient is equal to that of a pipe section of the same length.

• Simple structure, small size and light weight.

• Tight and reliable. Currently, plastic is widely used as the sealing surface material of ball valves, which has good sealing performance and has also been widely used in vacuum systems.

• Easy to operate, quick to open and close, just rotate 90° from fully open to fully closed, convenient for long-distance control.

• It is easy to maintain. The ball valve has a simple structure and the sealing rings are generally movable, making it easy to disassemble and replace.

• When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium. When the medium passes, it will not cause erosion of the valve sealing surface.

• It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be applied from high vacuum to high pressure. This type of valve should generally be installed horizontally in pipelines.
