High platform flange ball valve installation and maintenance considerations

1. Leave the valve stem in a rotated position.

2. Cannot be used for throttling.

3 Ball valves with belt drive should be installed upright.

Second, the working principle of the high platform flange ball valve is to make the valve open or blocked by rotating the valve. The ball valve is light and compact, can be made into a large diameter, reliable in sealing, simple in structure, and convenient in maintenance. The sealing surface and the spherical surface are often in a closed state and are not easy to be eroded by media. They are widely used in various industries.

Third, the high platform flange ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium. Ball valve is a new type of valve that has been widely used in recent years.

High platform flanged ball valve advantages

1. The fluid resistance is small, and its drag coefficient is equal to the length of the same length.

2. Simple structure, small size, light weight.

3. It is compact and reliable. At present, the sealing surface material of the ball valve is widely used with plastics and has good sealing performance. It has also been widely used in vacuum systems.

4. Easy to operate, fast opening and closing, as long as the rotation from 90 degrees from full open to fully closed, easy remote control.

5. Easy maintenance, ball valve structure is simple, the seal ring is generally active, removal and replacement are more convenient.

6. When fully open or fully closed, the sealing surfaces of the ball body and the valve seat are isolated from the medium. When the medium passes through, the sealing surface of the valve will not be eroded.

7. Wide range of applications, from small to several millimeters in diameter, up to a few meters in size, from high vacuum to high pressure can be applied. When the ball is rotated 90 degrees, all the spheres at the entrance and exit should be spherical, thus cutting off the flow.

High-platform flanged ball valve is a relatively new type of ball valve, which has some unique advantages of its own structure, such as the switch without friction, the seal is not easy to wear, and the opening and closing torque is small. This will reduce the specifications of the actuators fitted. Combined with multi-turn electric actuators, media adjustment and strict shut-off can be achieved. Widely used in petroleum, chemical, urban water supply and drainage and other conditions require strict cut off.
