Product Overview
The ash discharge ball valve evolved from the globe valve. It has the same 90-degree rotation action, except that the plug body is a sphere with a circular through-hole or passage along its axis. The ratio of the spherical surface to the passage port should be such that when the ball rotates 90 degrees, the inlet and outlet are completely presented with spherical surfaces, thereby cutting off the flow. The structural features of the pneumatic ash discharge ball valve are the same as those of the pulverized coal injection ball valve. It is an ideal device for controlling media such as dust-laden gas, particle-laden liquids, and powders, and is mainly suitable for blast furnace dust removal and ash discharge systems.

Product Features

1. Low 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. Currently, plastics are widely used as sealing surface materials for ball valves, providing good sealing performance, and it is also widely used in vacuum systems.

4. Convenient operation and fast opening/closing; it only takes a 90° rotation from fully open to fully closed, facilitating remote control.

5. Convenient maintenance. The pneumatic ball valve has a simple structure, and the sealing rings are generally movable, making disassembly and replacement relatively easy.

6. When fully open or fully closed, the sealing surfaces of the ball and seat are isolated from the medium, so the medium will not cause erosion to the valve's sealing surfaces when passing through.

7. Wide application range. Nominal diameters range from a few millimeters to several meters, and it can be applied from high vacuum to high pressure.
