ORBIT Valves STANDARD FEATURES
 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.
•  Injectable Packing For in-service  maintenance, stem packing material is injected through the packing fitting, giving complete control of fugitive emissions. (Available on all enclosed bonnet models.)
•  Single-seat Design The single, stationary seat in the ORBIT valve seals in both directions and avoids the problems of trapped pressure between seals.
•  Long Life 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.
• Top-entry Design In-line inspection and repair, after system depressurizing, simplifies maintenance.
OPERATING PRINCIPLE
Every ORBIT valve incorporates a proven tilt-and-turn operation that eliminates seal rubbing, which is the primary cause of valve failure.
When an ORBIT valve is closed, the core is mechanically wedged tightly against the seat, ensuring positive shutoff.
When an ORBIT valve begins to open, the core tilts away from the seat and line flow passes uniformly around the core face. This eliminates the localized high-velocity flow that typically creates uneven seat wear in ordinary ball, gate and plug valves. The core then rotates to the fully open position.
