Specialityvalve is a magnificent Sleeved Plug Valve Manufacturer in India. Sleeved plug valves are non-lubricated quarter valves that achieve sealing using a compressible sleeve as a sealing member. A sleeve valve takes the form of one or more machine sleeves. It places between the piston and the cylinder wall. In the cylindrical wall, the internal combustion engine rotates or slides. Ports in the side of sleeves come into alignment with the cylinder’s inlet and exhaust ports at the appropriate stages in the engine’s cycle.
The sleeved valve has begun to make something of a comeback, and most of the advanced engine research is concentrated on improving the internal combustion engine and design. The benefits of a sleeved plug- are zero maintenance, enhance lifestyle, better sleeve retention, sustainable inner lining, and a low coefficient of friction.
The design provides lower and consistent operating torques. The sleeved plug valves provide 360-degree port lips that help initiate self-cleaning action to remove scaling from the plug during the rotation. It has optimized the flow path which offers a higher flow coefficient that increases overall system efficiency.
The Plug Valve is a quarter-turn rotary motion manual valve. It offers a straightway passage through the ports so that fluid can flow through the opening plug (cylindrical or tapered plug) with a minimum of turbulence. The plug Valve is different from other valves due to its plug disc design. Most plug valves are used for directional flow control, even in a moderate vacuum, handling gas and liquid fuel, for safe handling of extreme temperature flow like boiler feed water.
Specialityvalve is the leading Sleeved Plug Valve Manufacturer in India which provides standard and customized valves which use materials like carbon and stainless steel. Its benefits are easy in-line adjustability, no cold- flow, and a 360-degree port lip design to ensure sleeve containment.

Advantages of sleeved plug valve
• High volumetric efficiency due to very large ports opening
• The size of the ports can be readily controlled
• Lower operating temperatures
• Low production cost
Disadvantages of sleeved plug valve
• Because of high friction first movement requires a large amount of force
• Actuators are required for larger valves
• Pressure drop is more due to reducing port
