Sleeved Plug Valve Design

Sleeved Plug Valve

Product Catalouge

Sleeved Plug Valve is a type of quarter-turn valve commonly used in various industrial applications. It is designed with a cylindrical or tapered plug that rotates inside a sleeve, which is made of an elastic or deformable material, such as rubber or synthetic polymer.

The plug has one or more holes or ports that allow the fluid to flow through the valve in the open position. When the plug is rotated 90 degrees, the ports are blocked by the sleeve, which creates a tight seal and stops fluid flow.

Sleeved plug valves are commonly used in applications requiring tight shutoffs, such as chemical processing, oil and gas production, and water treatment. They are also suitable for handling viscous fluids and abrasive materials, as the sleeve provides a protective barrier between the plug and the valve body.

One of the advantages of sleeved plug valves is their ease of maintenance. The sleeve can be easily replaced without removing the valve from the pipeline, saving time and reducing downtime. Additionally, the sleeve can be made of various materials to suit different applications and operating conditions.
