Orbit - Rising stem ball valves

Cameron’s ORBIT® valves are ideal for applications when zero leakage and frequent operation are demanded. They are used globally in gas processing plants using molecular sieve systems in switching service. No Rubbing Between Sealing Surfaces The tilt-and-turn action eliminates seal abrasion, which is the major cause of seat wear in conventional ball, gate and plug valves Top-entry Design In-line inspection and repair, after system depressurizing, simplifies maintenance Single-seat Design The single, stationary seat in the ORBIT valve seals in both directions and avoids the problems of trapped pressure between seals. Self-cleaning Tilting the core away from the seat before rotation causes immediate flow around 360 degrees of the core face. Product flow flushes any foreign material away from the seat without localized, high-velocity erosive flow. Mechanical Cam Closure The cam angle at the lower end of the stem provides a mechanically energized seal
