Velan currently supplies valves for delayed coker applications in the widest range of sizes and pressure classes in the industry – with a proven track record. Valves for 4-way switching, isolation, HP water, and steam service are included in this range.

With over 700 valves installed worldwide in coker service, Velan has proven itself as a major player in this extreme service. Single 90° rotary motion allow for simple and inexpensive actuation, while sturdy bellows maintain constant seat to ball contact. A 1-piece ball and stem construction provides optimal strength and prevents solids build-up in the ball-stem joint normally associated with 2-piece designs. Scraper type seats ensure self cleaning during normal operation, while steam purges maintain bellows and body areas free of coke build-up.
