Introduce:
Ball valve , opening and closing parts (ball) driven by the valve stem, and around the axis of the ball valve for rotating movement of the valve. It can also be used for fluid regulation and control, the hard seal V-type ball valve with V-type core and surfacing carbide metal valve seat has a strong shear force, especially suitable for containing fiber, small solid materials and other media. The multi-pass ball valve in the pipeline can not only flexibly control the medium confluence, shunt, and flow switch, but also can close any channel and make the other two channels connected. This type of valve shall generally be installed horizontally in the pipeline. Ball valve according to the driving mode is divided into: pneumatic ball valve, electric ball valve, manual ball valve.

A weir-type diaphragm valve is a specific design of diaphragm valve that features a raised lip or saddle in the valve body. The diaphragm comes into contact with this weir to form a seal and control fluid flow. Main parts and materials Name/Material CI WCB CF8 CF3 CF8M CF3M Body CI WCB CF8 CF3 CF8M CF3M Diaphragm […]
A straight-through diaphragm valve controls fluid flow in a pipeline using a diaphragm that moves vertically to open or close the flow path. The straight-through design allows fluid to pass directly through the valve, reducing pressure drop and maintaining efficient flow. It is commonly used in applications where reliable sealing and minimal obstruction are needed, […]
A plug valve controls fluid flow in a pipeline using a cylindrical or tapered plug with a central hole. The plug rotates within the valve body to open or close the flow path. When the plug aligns with the pipeline, fluid passes through. When turned so the hole is perpendicular to the flow, it blocks […]
A fluorine lined control valve regulates the flow of fluids in a pipeline, adjusting flow rate, pressure, and temperature. It works by changing the size of the flow passage using elements like plugs, balls, or diaphragms. Control valves are crucial in industrial processes for maintaining operating conditions and ensuring system efficiency. They can be operated […]
