The Actuator Division of Parker
Hannifin has furnished specialty
actuators for submerged and marine
operations for 35 years. It supplies
the US Military with actuators to
automate valves, deploy antennas,
open and close torpedo doors and

Most of these actuators are custom-
made to meet specific

actuators rated at 3000 psi and

engineering and sales team welcomes your input and
looks forward to helping develop products meeting your
specific needs. Parker Actuator Division is the industry
leader in actuator technology. We have invested in the
engineering and analysis tools to fully understand the
limits of our product offerings. We have the team in place
and the analysis and technical capabilities to evaluate
your special requirements and to work with your engi-
neers to establish an optimum solution.
Rack-and-pinion actuators offer the opportunity for the
customer to define and integrate specific features or
strengths into the actuator housings. If required, special
actuator housings can be fabricated from a machined
block or a weldment versus the standard cast housing.
This special housing can be designed with special
dimensional features and strength capabilities to inte-
grate directly into the customer’s structure. The actuator
assembly thus becomes a drop-in device with precision-
machined features defined by the customer, built-in
bearing capability, and other critical features in addition
to supplying rotary power and positioning. These values
are incorporated into one low-cost package the cus-
tomer can buy, without doubling up on the expense of
building similar features into his apparatus.
