Velan releases upgrades to its delayed coker isolation valves
3/27/2026 12:00:00 PM
A newly added lower tangential purge directs steam precisely to areas where coke accumulates in stagnant cavities, creating a loop‑flow around the ball for improved cleaning efficiency with a non‑plugging purge design.
This field‑proven targeted approach combined with Velan’s one‑piece ball and stem, robust bellows, and scraper‑type seats, delivers optimized purge performance, improved reliability, and long‑term service life, helping refiners minimize fouling and simplify maintenance in severe coking service while maintaining very low steam consumption.
