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-services maintenance, stem packing material Is injected through the packing fitting, giving complete Control of fugitive emission. (Available on all enclosed bonnet models.)
Single- Seat Design
The single, stationary seat in the ORBIT valves Seal in both direction And avoids the problem 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.
Optimum Flow
Full port or reduce port Openings Give high Cv Figures. System pumping efficiency is enhanced And Erosion problems are reduced.
Top-entry Design
In-line inspection and repair, after system Depressurizing, simplifies maintenance.
Dual Stem Guides
Hardened stem slots and tough guide pins Control the lift-and-turn action of the Stem.
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.
Low-torque operation
ORBIT valves turn easily because seal rubbing is eliminated.
Wear-resistance Hard facing on Core
The Core face is hard, polished material that will endure difficult service, without loss of sealing integrity.
Mechanical Cam Closure
The Cam angle at the lower end of the stem provides a mechanically energized seal.
