ORBIT
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. The tilt-and-turn action eliminates seal abrasion,  which is the major cause of seat wear in conventional ball, gate and plug valves. The single, stationary seat in the Orbit valve seals in both directions and avoids the problems of trapped pressure between seals. Orbit valves replace troublesome ball valves, gate valves, globe valves and plug valves. The Orbit design has performance advantages that reduce plant outage and reduce the cost of ownership. The core face is a hard, polished material that will endure difficult service, without loss of sealing integrity. Hardened stem slots and tough guide pins control the lift-and-turn action of the stem. 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. Orbit valves replace troublesome ball valves, gate valves, globe valves and plug valves.
