Sleeve Plug Valve
Bubble-tight shut-off for the most demanding service conditions
The XOMOX sleeve plug valve is the industry benchmark for tight shut-off in aggressive chemical, petrochemical, and refinery service. A precision-machined PTFE sleeve and tapered plug deliver bubble-tight performance over long service life, with full in-line maintainability.
Decades-proven design used on the most critical isolation duties in refineries and chemical plants worldwide. Bubble-tight performance, low total cost of ownership, and full in-line maintainability.
As an authorized Crane / XOMOX partner, we provide engineering selection, sleeve and plug service, and field installation support — not just supply.
Engineered
where it matters
Bubble-tight shut-off
PTFE sleeve maintains ANSI Class VI tight shut-off across the full life of the valve, eliminating fugitive emissions.
Self-adjusting sleeve
The PTFE sleeve compensates for wear automatically — no in-service adjustment required, even after years of cycling.
Full in-line service
Sleeve and plug replacement without removing the valve body from the line. Reduces turnaround time and cost.
Fire-safe to API 607
Available with secondary metal-to-metal seat backup for fire-safe certification, critical for upstream and refinery service.
Zero dead volume
Streamlined flow path with no cavities — ideal for slurries, polymers, and abrasive media that would clog conventional valves.
Bi-directional
Equal performance in both flow directions — simplifies install, eliminates orientation errors during turnaround.
