1. The fluid resistance is small, and its resistance coefficient is equal to that of the pipe segment of the same length. 2. Simple structure, small size, light weight. 3. Tight and reliable, good sealing, has also been widely used in vacuum systems. 4. Easy to operate, open and close quickly, from full open to full close as long as the rotation of 90 degrees, easy to remote control. 5. Easy maintenance, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient. 6. When fully open or fully closed, the sealing surface of the ball and the seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when it passes through. 7. Wide range of application, small diameter to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied. High platform ball valve according to its channel position can be divided into straight-through, three-way and right-angle. The latter two ball valves are used to distribute the medium and change the flow direction of the medium.| Product | 3 Way Ball Valve L and T type |
