ORBIT rising stem ball valve’s unique tilt-and-turn design reduces seal rubbing and delivers reliable performance. It is the proven technology for arduous process conditions, including high-temperature, critical isolation to molecular sieve switching services.


  • No rub between sealing surfaces
  • Injectable packing
  • Single-seat design
  • Long life
  • Optimal flow: full port or reduced port openings give high CV figures
  • Top-entry design
  • Dual stem guides
  • Self-cleaning
  • Low-torque operation
  • Wear-resistant hard facing on core
  • Mechanical cam closure

ORBIT Valve are ideally suited for:

  • Mol sieve dehydration switches valves
  • Flowlines
  • Meter isolation
  • Dryer switching
  • Block and bypass
  • Product segregation
  • Emergency shutdown
  • Suction and discharge isolation
  • Heat transfer fluids/hot oil
  • Hydrogen service
  • Many additional applications

How ORBIT Valve work

To close an ORBIT valve,
as the handwheel is
turned, the stem begins
to lower.
Precision spiral grooves in
the stem act against fixed
guide pins, causing the
stem and core to rotate.

Continued turning of the
handwheel rotates the
core and stem a full 90
degrees without the core
touching the seat.

Final turns of the
handwheel mechanically
wedge the stem down,
pressing the core firmly
against the seat.
