I. Introduction
Contromatics offers one of the largest ranges ofpneumatic rack andpinion actuators onthe market.
Contromatics
actuators are designed tooperate with pressurized air, but will function equally aswell with
hydraulicfluid,
water orinert fluids. Our actuators are designed tooperate within the pressure range of 20PSIG
to 150 PSIG
and are offered intwo styles: the Double Acting model andtheSpring Return. The double acting
modelis
available in90°,120°,135° and 180° versions. The Spring Return version isavailable only asa 90°
model. The
double acting and spring return actuators can easily be field converted toother configurations by
insertionor
removal ofthe unique patented Contromatics springcartridges.
A. Storage
All actuators are factory lubricated for 2,000,000 cycles under normal operating conditions. The actuator ports
are plugged to prevent liquids or other materials from entering the actuator during shipment. Ifthe actuators are
to be stored for a long period of time before installation, the units should be stroked periodically to prevent the
seals from setting. (Note: the plugs must be removed in order to stroke actuator.) Recommended storageis
indoors, andthe units should be protected against weather andother harmfulelements.

IV. Operation
A. Principals of Operation (Double Acting)
The Contromatics pneumatic actuator has simple operational characteristics. Port A is connected to the interior
cavity
between the pistons. Port B is connected to the end cap cavities (See Figures 4.1-4.2 below). If port A is
pressur-
ized (Fig. 4.1), air flows between the two pistons pushing them apart. Air is, in turn, exhausted out of port
B and
the pinion is rotated until the pinion cam is stopped by the open limit stop, resulting in the open position of
the
actuator. In order to rotate the actuator back to the closed position, air pressure must be removed from port A
and
applied to port B. Pressurizing port B (Fig. 4.2) will allow air to move into the cavities between the pistons
and the
endcaps pushing them together. Air is, in turn, exhausted out of port A and the pinion is rotated until the
pinion
cam is stopped by the closed limit stop bolt, resulting in the closed position of theactuator.
The above illustrations show the paths taken by the pressurized air (blue), the exhausting air (red), and the resulting
state of the actuator.
B. Principals of Operation (Spring Return)
The opening stroke of the spring return model functions just like the double acting model. By pressurizing port A
as shown in Fig. 4.3 the actuator opens, exhausts air like the double acting model, and compresses the springs.
However, to close the actuator, air pressure is removed from port A and allowed to exhaust. Once this is done the
encapsulated springs will return the actuator to its closed position and air will be exhausted out of the A portas
detailed in Fig. 4.4 below.
The above illustrations show the paths taken by the pressurized air (blue), the exhausting air (red) and the resulting
state of the actuator.

NOTE: In the case of a spring return model even though port A is the only port that needs to be pressurized in
order
to operate the actuator, air still must be allowed to enter and exit through port B unobstructed for proper
operation.
Contromatics both recommends and supplies filters or recirculation blocks that will maintain airflow
but prevent debris from entering the actuator. Consult Contromatics for specific applications and more
information.

C. Fail Positions
The Contromatics actuator standard operation is counterclockwise to open and clockwise to close. This is referred
toas
a “fail clockwise” configuration or FCW. However, it is also available in an FCCW or “fail
counterclockwise”
configuration. Figures 4.5 & 4.6 show the same actuator with the piston and pinion orientation
changed to convert
the actuator from the FCW to the FCCW configuration. FCW is referred to as “fail closed”
and FCCW as“fail
open” due to its intended effect on the valve. In the diagrams below, the hollow arrows show
the directionthe
pistons move due to the spring force, and the solid arrows show rotation of the pinion as it travels
to thefail
position.
FCW (Fail Closed)Fig.4.5
Fig. 4.5 shows a FCW, spring return actuator going from the open position (left) to the fail, or closed, position
(right).
FCCW (Fail Opened) Fig.4.6
Fig. 4.6 shows a FCCW, spring return actuator going from the open position (left) to the fail, or closed, position
(right).
NOTE: All statements above assume the valve is a quarter turn valve that opens counterclockwise and closes
clockwise.
Further, it also assumes that the actuator is spring return Since a double acting actuator will always fail
in
its last position (discounting any forces the valve may exert on the actuator). See also Table below.
