Product description
The ball valve switch is light and small, and its caliber can be large. It is reliably sealed with simple structure and is easy to be maintain. As the sealing surface and ball surface are always closed and are difficult to be scoured by medium, it is widely used in various industries.
 
Product features
1. Small hydraulic resistance, and its resistance coefficient is the same as the tube of same length;
2. Simple structure, small and light;
3. Compact and reliable, sound sealing performance for plastic is widely used for sealing surface of the ball valve contributing to the large-scale application to vacuum system.;
4. Easy to operate, fast opening and closing for it can be switched from fully opened to closed by only rotating 90 degrees and easy to be controlled from long distance;
5. Easy to maintain, and simple ball valve structure. Sealing ring is mostly movable to facilitate convenient removal and replacement;
6. When it is fully opened or closed, the ball valve and the sealing surface of valve seat are separated from medium , thus the medium will not lead to corrosion of the sealing surface of valve when passing through;
7. Wide application sphere, its diameter varies from several millimeters to few meters, and it can be applied under high vacuum conditions or high pressure.
