Sanitary Ball Valve is a relatively new type of ball valve. It has some characteristics 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 petroleum, chemical industry, urban water supply and drainage and other working conditions that require strict shutoff. So do you know what are the advantages and disadvantages of high-platform ball valves?
1. Advantages of high-platform ball valves:
1. High-platform ball valves have a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be used from high vacuum to high pressure.
2. High-platform ball valves have a simple structure, small size and light weight.
3. Tight and reliable. At present, the sealing surface material of ball valves widely uses plastics with good sealing performance, and has also been widely used in vacuum systems.
4. High-platform ball valves are easy to operate and open and close quickly. From full open to full closed, just rotate 90°, which is convenient for long-distance control.
5. Easy maintenance, the ball valve has a simple structure, and the sealing ring is generally movable, which is convenient for disassembly and replacement.

6. When the high-platform ball valve is fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium. When the medium passes through, it will not cause erosion of the valve sealing surface.

7. The fluid resistance of the high-platform ball valve is small, and its resistance coefficient is equal to that of the pipe section of the same length.

2. Disadvantages of high-platform ball valve:

1. Its adjustment performance is worse than that of the stop valve, especially the pneumatic valve (or electric valve).

2. Because the main valve seat sealing ring material of the ball valve is polytetrafluoroethylene, it is inert to almost all chemical substances, and has the comprehensive characteristics of small friction coefficient, stable performance, not easy to age, wide temperature application range and excellent sealing performance.

The high-platform ball valve is an ordinary ball valve pre-installed with a high platform during design and manufacturing, so according to the different classifications of ball valves, high-platform ball valves can be divided into many types.
