Special Material Valve have the same 90-degree rotation action, but the difference is that the plug body is a sphere with a circular through hole or channel passing through its axis. Special Material Valve are mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It only needs to rotate 90 degrees and a very small torque to close tightly. Special Material Valve are suitable for use as switches and cut-off valves, but recent developments have designed Special Material Valve to have throttling and flow control functions, such as V-type Special Material Valve.
The main features of Special Material Valve are compact structure, reliable sealing, simple structure, easy maintenance, the sealing surface and the spherical surface are often in a closed state, not easily eroded by the medium, easy to operate and maintain, suitable for general working media such as water, solvents, acids and natural gas, and also suitable for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, etc., and are widely used in various industries. The valve body of Special Material Valve can be integral or combined.
1. Small fluid resistance, full-diameter Special Material Valve have basically no flow resistance.
2. Simple structure, small size, light weight.
3. Tight and reliable. It has two sealing surfaces, and the sealing surface materials of Special Material Valve are currently widely used in various plastics, with good sealing and can achieve complete sealing. It has also been widely used in vacuum systems.
4. Easy to operate, quick opening and closing, only need to rotate 90° from full open to full closed, which is convenient for long-distance control.
5. Easy maintenance, Special Material Valve have a simple structure, and the sealing rings are generally movable, which is convenient for disassembly and replacement.
6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and when the medium passes, it will not cause erosion of the valve sealing surface.
7. Wide range of applications, diameters range from a few millimeters to several meters, and can be used from high vacuum to high pressure.
8. Since Special Material Valve have wiping properties during the opening and closing process, they can be used in media with suspended solid particles.
