Sleeve Type Plug Valve

The valve uses a resilient sleeve sealing structure between the plug and body, reducing direct metal contact during operation and helping minimize wear on sealing surfaces. This design supports consistent torque performance and extended service intervals in applications involving liquids, gases, and industrial process media.
Sleeve Type Plug Valves are commonly used in chemical processing, water treatment, oil and gas, power generation, and general industrial fluid control systems where dependable isolation is required.

Sleeve Sealing Structure: Features a flexible sleeve interface that creates a continuous barrier around the plug to secure tight shut-off integrity.
Low Operating Torque: Eliminates surface binding during rotation to ensure smooth valve actuation and reduce mechanical resistance.
Full Flow Passage: Incorporates a streamlined internal profile to maintain high flow capacity and minimize pressure drop in open positions.
Corrosion Adaptability: Accommodates various alloy and polymer combinations to match specific chemical compositions and fluid characteristics.

Quarter-Turn Operation: Rotates precisely ninety degrees between open and closed positions for rapid pipeline isolation control.
Sleeve-Based Sealing: Maintains constant pressure contact between the resilient sleeve and plug surface to establish a secure fluid barrier.
Bidirectional Shut-Off: Engineered to isolate flow effectively from both directions to accommodate flexible piping system configurations.

Chemical Processing Systems: Provides secure pipeline isolation in manufacturing environments handling reactive or corrosive process fluids.
Water & Wastewater Treatment: Regulates municipal and industrial fluid networks requiring frequent cycle actuation and dependable shut-off.
Oil & Gas Facilities: Controls upstream and downstream fluid transfer lines handling hydrocarbon liquids and pressurized gases.
Power Generation Plants: Integrates into auxiliary water and steam handling loops designed for continuous industrial operation.

Precision Machining: Valve bodies and plugs undergo strict dimensional cutting procedures to ensure precise alignment and internal component fit.
Sleeve Installation: Resilient sealing sleeves are fitted according to strict engineering tolerances to guarantee uniform sealing pressure.
Assembly Inspection: Completed assemblies undergo preliminary dimensional and mechanical alignment checks prior to testing phases.

Material Verification: Incoming raw metals and polymer compounds are tested against designated composition standards prior to release.
Pressure Testing: Units undergo hydrostatic and pneumatic pressure evaluations to verify structural shell integrity and seat tightness.
Functional Testing: Operating torque, stroke rotation, and shut-off capability are verified prior to final warehouse packaging.

Material Selection: Body, plug, and sleeve configurations can be tailored to match specialized corrosion resistance and temperature limits.
Dimension & Connection: Flange drillings, face-to-face lengths, and end connections can be adapted to specific piping layout demands.
Actuation Integration: Direct mounting pads accommodate manual gearboxes, pneumatic piston drives, or electric motor actuators.
