Description
Sleeved Plug Valve Manufacturer & Exporter in India
FlowBiz Exports manufactures high-reliability Sleeved Plug Valves designed for non-lubricated, bubble-tight shut-off in corrosive, erosive, and hazardous fluid handling applications. Featuring a high-grade PTFE/RPTFE sleeve encapsulated between the valve body and the tapered plug, these non-lubricated plug valves eliminate the risk of media contamination, line sticking, and regular maintenance associated with lubricated valves.
Key Performance Features & Design
- Non-Lubricated Sleeve Construction: Full-contact PTFE sleeve provides 360° circumferential sealing without requiring grease or line lubrication, ensuring zero fluid contamination.
- Bi-Directional Bubble-Tight Shut-Off: Precision-machined tapered plug compresses against the resilient sleeve, delivering 100% leak-free performance across both directions.
- Self-Cleaning Action: As the plug rotates within the sleeve, it automatically wipes off sticky deposits and slurry particulates, preventing seat clogging and scaling.
- In-Line Adjustable Sealing: Top-entry adjustment bolts allow fast inline adjustment of the plug to restore tight sealing without removing the valve from the pipeline.
