Plug Valve Manufacturer in Germany

3 min read

Valvesonly Europe is the foremost Plug Valve Manufacturer in Germany. A plug valve is a valve with a cylindrical or tapered plug that can be rotated within the valve body to control the flow of fluids. It is designed to start, stop, or regulate flow by turning the plug, which can be fully or partially opened or closed.


• Flow Control: Primarily used to start, stop, or regulate the flow of fluids (liquids or gases) in a pipeline.

• Isolation: Provides tight sealing to isolate sections of a pipeline, preventing fluid from passing through when fully closed.

• On/Off Operation: Quick and simple operation with a quarter-turn mechanism, enabling rapid opening or closing of the valve.

The basic working principle involves the rotation of a cylindrical or tapered plug inside the valve body. Here’s a step-by-step breakdown:

• Valve Body: The valve consists of a body with an internal passageway and an opening that accommodates the plug.

• Plug: The plug, often cylindrical or tapered in shape, is inserted into the valve body.

• Rotation: The plug is connected to a shaft or stem that protrudes outside the valve body for manual or automated operation.

• Flow Control: By rotating the plug using the stem or handle, the opening through the valve body can be adjusted. When the plug is turned perpendicular to the flow direction, it blocks flow (closed position). Rotating the plug parallel to the flow allows fluid to pass through (open position).

• Sealing: When the plug is fully closed, it creates a tight seal against the valve body, preventing fluid from passing through.

• Materials: Plug valves are made of various materials depending on the application, including metals, plastics, or elastomers.
