Hydraulic ball valves are widely used in petroleum refining, long-distance pipelines, chemical, papermaking,
Advantages:
1. The fluid resistance is small, and the full diameter ball valve has little flow resistance.
2. Simple structure, small size and light weight.
3. Tight and reliable. It has two sealing surfaces, and at present, all kinds of plastics are widely used in the sealing surface materials of ball valves, and the sealing property is good and can be completely sealed. It has also been widely used in vacuum systems.
4. Easy to operate, quickly to open and close, only 90 °rotation from full to full, which is convenient for long distance control.
5. Convenient maintenance, simple structure of ball valve, sealing ring is generally movable, disassembly and replacement are more convenient.
6. When the ball and seat are fully open or closed, the sealing surface of the sphere and seat is isolated from the medium, and the sealing surface of the valve will not be eroded when the medium passes through.
7. The range of application is wide, the path is from small to several millimeters, large to several meters, and can be applied from high vacuum to high pressure.
8. The ball valve can be used in the medium with suspended solid particles because of its wiping property in the opening and closing process.
The hydraulic ball valve consists of two parts of a hydraulic device and a ball valve. The hydraulic device drives the valve rod to rotate to drive the ball to rotate to achieve the purpose of opening and closing.

Main characteristics of hydraulic ball valve:
1. The valve ball and valve body of the ball valve are made of high-quality stainless steel, and the anti-corrosion performance is good.
2. metal seal can be used to meet the drilling mud medium environment.
3. The structure size of hydraulic drive part is small, which can meet the narrow installation environment.
4. The torque is large, and the use requirement can be met by the liquid control table of the anti-spray device.
