Apollo®
CompacTorque™
Pneumatic Actuators Overview
Apollo® CompacTorque™ actuators
are the most advanced rack and pinion actuators on the
market today. From corrosion protection to versatility
in application, these actuators offer you the ultimate
in design and selection. Their outstanding design starts
with hard anodized aluminum construction, in your choice
of polyester powder coatings, 316L stainless steel pigmented
polyester electrostatic coating or electroless nickel
coating. This range of materials assures you the maximum
in corrosion protection at an affordable cost.
Our unique Universal Shaft Adapter
(USA) makes direct mounting to your favorite butterfly
valve easier than ever. The precision replaceable
inserts feature variable internal geometry to meet any
custom requirements. The standard insert material
is high-strength FLNC-4408. Optional stainless
steel inserts are available. CompacTorque™
actuators are available in spring return or double-acting
units which convert easily in the field to a spring
return design by simply adding the correct number of
pre-loaded springs to the standard housing. Specially
designed spring cartridges make our spring return actuators
inherently safe. Other standard features include
internal and external travel stop adjustments, high
temperature, low coefficient of friction body bearings
to absorb the side thrust of the pistons, internal piston
guides and high temperature, low friction piston bearings.
The actuators' internal porting
reduces the cost of external tubing which can be easily
damaged. All top mounting dimensions for accessory
mounting and pneumatic supply ports conform to the latest
NAMUR specifications. Actuators can be direct
mounted to 1-1/2 to 24" Apollo valves. The standard
spring cartridge system is designed to operate on 40,
60, 80, 100 and 120 PSI service.
