Arc-shaped rotary valve——brings a brand-new solution to sanitary fluid control
Unique structure
The most eye-catching feature of the arc-shaped rotary valve is its rotary single disc design, which enables the disc to rotate 360 degrees in all directions. This unique design makes it more adept at controlling fluids. When the fluid needs to pass through the valve, the single valve disc rotates lightly, smoothly opening the channel, reducing the obstruction to the fluid and lowering energy loss. When it is necessary to cut off the fluid, the valve disc can quickly rotate and closely adhere to the valve seat, achieving a tight seal and eliminating any possibility of leakage. This 360-degree rotating single disc design makes the opening and closing process of the valve more smooth and efficient, greatly improving the response speed and control accuracy of the valve, and making fluid control in industrial production more precise and reliable. The valve body of the arc valve can clean the pipeline through a rubber PIG head (PIG). When the rubber pig head (PIG) is sent into the pipeline, the dirt adhering to the pipe wall is removed by friction, and at the same time, the accumulated substances are washed away by the annular gap jet.
Multiple valve body structures and diverse flow direction switching
The arc-shaped rotary valve can also be equipped with different valve body structures to achieve multiple flow direction switching and meet the complex and changeable industrial demands. For instance, in some production processes that require flexible adjustment of fluid direction, by changing the valve body structure, the arc-shaped rotary valve can easily achieve forward and reverse fluid flow, as well as switching between different branch pipelines. Precisely guide the fluid to flow in an orderly manner within the pipeline network. It provides a solid guarantee for the smooth operation of industrial production.
Highlights of the full-bore design
The full bore design is another prominent feature of the arc-shaped rotary valve. The full bore design of the arc-shaped rotary valve enables the pigging device to pass through smoothly without any hindrance. This not only enhances the efficiency of the pigging operation, but also reduces the wear and energy consumption of the pigging device when passing through the valve. Meanwhile, the full-bore design can also ensure that the fluid maintains a uniform flow rate and pressure when passing through the valve, reducing pressure loss and the occurrence of turbulence, and enhancing the conveying capacity and stability of the pipeline system. For some industrial applications with high requirements for flow and pressure, such as long-distance natural gas pipelines and material transportation in large-scale chemical plants, the full bore design advantages of arc-shaped rotary valves are fully demonstrated, making significant contributions to the efficient and stable operation of the entire industrial system.
