ORBIT Valves for Mol Sieve Dryers
PRODUCT HISTORY
Cameron’s ORBIT® valves have set the standard in mol
sieve switching valves for more than 40 years. With
temperatures cycling between 60° F and 800° F (15° C
and 427° C) and tower changes three or four times every
day, it takes a tough valve to survive in mol sieve service.
Hot, abrasive carryover from mol sieve beds will destroy
the seals in ordinary valves, causing leakage and system
shutdown. Cameron’s ORBIT valves thrive in these difficult
conditions, lasting more than two to five times longer
than conventional ball valves.
Utilizing tilt-and-turn operation and mechanical cam
action of the seating surfaces during closure, ORBIT valves
avoid the damage caused by scratching and tearing that
affects other types of valves.
The unique operation of the ORBIT valve achieves tight
sealing, again and again, even when there is low
differential pressure across the valve.
ORBIT rising stem, top-entry valves are approved and used
by leading dryer manufacturers because of their reliability
in mol sieve service.
ORBIT valves are specified by process gas plants and
licensors’ operations worldwide.
In the fully open position,
there is unobstructed flow
through the valve.
Precision dual-spiral
grooves in the stem act
against fixed guide pins,
causing the stem and
core to rotate.
Continued closing action
rotates the core and stem a
full 90 degrees without the
core touching the seat.
Final closing action
mechanically cams the
stem down, pressing
the core firmly against
the seat.

SCHEMATIC
Schematic of Mol Sieve Dryer System Using ORBIT Sequence Switching Valves
Typical Challenge
Wet gas leaking through
ordinary valves will cause dryer
efficiency to decline.
CAMERON’S SOLUTION
ORBIT valves are cammed
positively closed, eliminating
wet gas leakage.
Typical Challenge
Leaking valves can prolong
the regeneration time and
waste energy.
CAMERON’S SOLUTION
The ORBIT valve design
eliminates rubbing between seat
sealing surfaces, ensuring zero
leakage and conserving energy.
Typical Challenge
Daily operation in hot, abrasive
service can create high
maintenance costs.
CAMERON’S SOLUTION
ORBIT valves provide reliable
long life in hot, abrasive service,
with reduced maintenance.

ORBIT Actuators
Cameron’s ORBIT sequence switching valves can be either
manual or power operated.
ORBIT pneumatic actuators have a performance record to
match the long life and low maintenance of the ORBIT
valves that they control.
ORBIT actuators can be easily retrofitted to manual
ORBIT valves in the field, without removing the valve
from the line.
