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

2. Simple structure, small volume, light weight.

3. Tight and reliable, the ball valve sealing surface material widely used plastic, good sealing, vacuum systems have also been widely used.

4. Easy to operate, open and close quickly, from fully open to fully closed, as long as the rotation of 90 °, easy to control from a distance.

5. Easy to maintain, simple structure, the seal is generally movable, disassembly and replacement are relatively convenient.

6. In fully open or fully closed, the ball and seat sealing surface and media isolation. The medium will not cause erosion of the sealing surface of the valve when it passes.

7. Wide range of application, the diameter from a small to a few millimeters, large to several meters, from high vacuum to high pressure can be applied.

Stainless steel two-piece ball valves can be divided into straight-through, three-way and right-angle type according to their passage position. The latter two types of ball valves are used to distribute the medium with changing the flow direction of the medium. Stainless steel two-piece ball valve

2 installation and maintenance

1. To leave the position of the valve handle rotation.

2. Cannot be used as a throttle.

3 Ball valve with transmission mechanism should be installed upright.

Two, stainless steel two-piece ball valve works by rotating the valve love to make the valve open or closed. Ball valve switch light, small size, can be made into a large diameter, reliable sealing, simple structure, easy maintenance, sealing surface and spherical surface is often in a closed state, not easy to be eroded by the media, widely used in various industries.

Three, stainless steel two-piece ball valve in the pipeline is mainly used to do cut off, distribution and change the direction of media flow. Ball valve is a new type of valve widely used, it has the following advantages: 1:

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

2. Simple structure, small volume, light weight.

3. tight and reliable, the ball valve sealing surface materials are widely used plastic, good sealing, has been widely used in the vacuum system.

4. easy to operate, open and close quickly, from fully open to fully closed as long as the rotation of 90 °, easy to control from a distance.

5. easy to maintain, the ball valve structure is simple, the seal is generally movable, disassembly and replacement are relatively easy.

6. In the fully open or fully closed, the ball and seat sealing surface and media isolation, the media through, will not cause erosion of the valve sealing surface.

7. Wide range of application, diameter from small to a few millimeters, large to several meters, from high vacuum to high pressure can be applied. When the ball is rotated 90 degrees, all the spherical surfaces should be presented at the inlet and outlet, thus cutting off the flow.

Stainless steel two-piece ball valve is a relatively new type of ball valve, which has some unique advantages of its own structure, such as frictionless switch, seal is not easy to wear, opening and closing torque is small. This can reduce the specification of the actuator. Equipped with multi-turn electric actuator, it can realize the regulation and tight cut-off of the medium. Widely used in petroleum, chemical industry, urban water supply and drainage, etc. requiring strict cut-off conditions.
