Non lubricated sleeved plug valve manufacturer in Germany

Valvesonly Europe is the biggest Non Lubricated Sleeved Plug Valve Manufacturer in Germany. A nonlubricated sleeved plug valve is a type of valve used to control the flow of fluids in a pipeline.

A plug valve is a quarter-turn rotational motion valve that uses a cylindrical or tapered plug with a passage through it to control the flow of fluids. The non-lubricated aspect means that these valves are designed to operate without the need for external lubrication, which can be advantageous in certain applications where lubrication may contaminate the fluid or cause maintenance issues.

The primary function of a non-lubricated sleeved plug valve is to start, stop, or regulate the flow of fluid within a pipeline. By turning the valve handle or actuator, the plug inside the valve rotates, allowing or restricting the flow of the fluid through the passage. When fully open, the plug aligns with the pipeline, enabling unrestricted flow. Conversely, when fully closed, the plug blocks the passage, halting the flow of fluid entirely.


·       Sleeved Design: The sleeved construction involves a resilient sleeve or lining inside the valve body. This sleeve, often made of materials like PTFE (polytetrafluoroethylene), acts as a barrier between the flowing medium and the valve body, reducing friction and wear on the metal components. It also aids in creating a tight seal when the valve is closed, preventing leakage.

·       NonLubricated Operation: Unlike traditional plug valves that require lubrication for smooth operation, non-lubricated versions use specialized materials and design features to eliminate the need for external lubrication. This can be beneficial in industries where lubricants might react with the fluid being transported or cause contamination.

·       Rotation Control: By turning the valve handle or actuator, the plug inside the valve rotates either perpendicular to the flow (closed position) or parallel to the flow (open position), thereby regulating the flow of the fluid. The design allows for quick and efficient control of the flow with a simple quarter-turn motion.

·       Sealing Mechanism: When the valve is closed, the plug creates a seal against the resilient sleeve, preventing the fluid from passing through. This sealing mechanism helps maintain the integrity of the pipeline system by minimizing or eliminating leaks.

A manufacturer of Non Lubricated Sleeved Plug Valve in Germany should always prioritize a thorough understanding and strict adherence to safety guidelines and maintenance procedures during the operation or installation of these valves. This commitment is essential to guarantee optimal performance and safety within the system.
