Lubricated plug valve suppliers in UAE

Middleeast valve is the best Lubricated plug valve suppliers in UAE. We supply to cities like Ajman, Khor Fakkan, AI Ain.

A lubricated plug valve is a type of valve that uses a lubricated tapered or cylindrical plug to control the flow of fluids. The plug has a hole through its center and can be rotated within the valve body to align with the flow path, allowing or blocking the passage of fluid. Lubrication helps to minimize friction and wear between the plug and the valve body, ensuring smooth operation and longevity.

The working mechanism of a lubricated plug valve involves the following steps:

Closed Position: When the valve is in the closed position, the solid part of the plug blocks the flow path, preventing any fluid from passing through.

Opening the Valve: To open the valve, the plug is rotated, typically by turning the valve handle or actuator. As the plug rotates, the hole in the plug aligns with the flow path, allowing fluid to pass through the valve.

Lubrication: Lubrication is introduced into the valve through a grease fitting. The lubricant forms a seal between the plug and the valve body, reducing friction and wear. It also helps to prevent leaks and provides a smoother operation.

Open Position: When the plug's hole is fully aligned with the flow path, the valve is in the open position, allowing maximum fluid flow.

Closing the Valve: To close the valve, the plug is rotated back to its original position, blocking the flow path once again.

Benefits

Low Operating Torque: The lubrication significantly reduces friction between the plug and the valve body, resulting in lower operating torque. This makes it easier to operate the valve, especially in high-pressure applications.

Tight Sealing: The lubricant forms a seal around the plug, providing excellent sealing capabilities. This helps to prevent leaks and ensures reliable operation even in high-pressure and high-temperature environments.

Durability: The lubrication reduces wear and tear on the valve components, extending the valve's service life. This durability makes lubricated plug valves suitable for demanding applications.

Suppliers in the UAE offer Lubricated Plug Valve with the option of either full port or reduced port designs. In a full port valve, the plug's through-hole matches the pipeline's diameter, whereas in a reduced port valve, the through-hole is smaller than the pipeline diameter. Full port valves are ideal for situations demanding high flow rates, while reduced port valves are chosen for applications where lower flow rates are adequate.
