Straight through type rubber lined diaphragm valve

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, […]

Fluorine lined plug valve

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 […]

Fluorine lined control valve

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 […]
