Sanitary Ball Valve and flange gate valve are valves of the same type, the difference is that its closing piece is a sphere, which rotates around the center line of the valve body to achieve opening and closing. Ball valves are mainly used in pipelines to cut off, distribute and change the flow direction of the medium. Two-piece ball valves and three-piece ball valves are a new type of valve that has been widely used in recent years.

Advantages of high platform ball valves

1. Small fluid resistance, its resistance coefficient is equal to that of a pipe section of the same length.

2. Simple structure, small size and light weight.

3. Tight and reliable. At present, the sealing surface material of ball valves is widely used in plastics, which has good sealing performance and has been widely used in vacuum systems.

4. Easy to operate, open and close quickly, just rotate 90° from full open to full closed, which is convenient for long-distance control.

5. Easy maintenance, the ball valve has a simple structure, the sealing ring is generally movable, and it is convenient to disassemble and replace.

6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when passing through.
7. Wide application range, diameters range from a few millimeters to several meters, and can be used from high vacuum to high pressure. When the ball rotates 90 degrees, the inlet and outlet should all present a spherical surface, thereby cutting off the flow.

High platform ball valve

High platform ball valve is a relatively new type of ball valve. It has some special features of its own structure, such as no friction when switching, the seal is not easy to wear, and the opening and closing torque is small. This can reduce the specifications of the actuator. Equipped with a multi-turn electric actuator, it can achieve the adjustment and strict shutoff of the medium. It is widely used in working conditions that require strict shutoff, such as petroleum, chemical industry, and urban water supply and drainage.

The ball of the ball valve is fixed and does not move after being pressurized. Fixed ball ball valves are all equipped with floating valve seats. After being pressurized by the medium, the valve seat moves, so that the sealing ring is pressed tightly against the ball to ensure sealing. Bearings are usually installed on the upper and lower shafts of the ball, with a small operating torque, suitable for high-pressure and large-diameter valves.
In order to reduce the operating torque of the ball valve and increase the reliability of sealing, oil-sealed ball valves have appeared. Special lubricating oil is injected between the sealing surfaces to form an oil film, which enhances the sealing and reduces the operating torque. It is more suitable for high-pressure and large-diameter ball valves.
