Stainless Steel 304 1 pc 4 inch ball valveProduct Description;
Feature of 1 pc 4 inch ball valve:
1 pc 4 inch ball valve. Ball ball valve is used with a circular channels as open-close, sphere with the valve rod rotation to realize on-off movement. Ball valve open-close part is a perforated sphere, perpendicular to the axis of rotation of the channel, so as to achieve the aim of opening and closing the channel. Ball valve is mainly used for medium truncated or through pipeline and equipment, can also be used for regulation and control of the fluid, the ball valve has fluid resistance small, simple structure, small volume, light weight, compact and reliable, convenient operation and maintenance, and does not cause the valve sealing surface erosion, wide application scope.
1 pc ball valve in the pipeline is mainly used to do cutting, distribution, and change the flow direction of medium. Ball valve is widely used in recent years a new type of valve, it has the following advantages:
1. The fluid resistance is small, its resistance coefficient with section of equal length.
2. Simple structure, small volume, light weight.
3. Compact and reliable, the widespread use of plastic ball valve sealing surface of materials, good sealing, also has been widely used in the vacuum system.
4. Easy to operate, open and close quickly, from open to close just rotate 90 °, is advantageous for the remote control.
5. Easy maintenance, simple structure of ball valve, sealing ring, which generally remove replacement is more convenient.
6. In the fully open or fully closed, the ball and seat sealing surface and the dielectric isolation, medium through, can not cause the valve sealing surface erosion.
7. Applicable scope is wide, size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.Ball rotated 90 degrees in the inlet and outlet should be completely present spherical, thereby blocking flow. Materials of major parts:
