D2000 Quick-actuating Closure


Safe. Reliable. Certain.  The industry depends on the D2000 quick-actuating closure to ensure safe, reliable and certain access to pipelines—and it’s been that way for almost 20 years.

Now, the most trusted closure on the market comes with the ProSeries ™ Advantage.

Which means we’ve kept the safety and ease of use features that set the D2000 apart—like allowing your operator to stand to the side during opening and closing, operations performed in a fast, single motion. But now it fits a broader range of applications with shorter lead time, code compliance and, as always, the consistent quality you expect from T.D. Williamson.

Best used for: pig traps, filters, strainers, scrubbers, heat exchangers, blowdowns, and other vessels
