Alternative Energy To meet economically viable cost targets ($/kWh) that compare to those of fossil-fuel power supply solutions, solar-power equipment suppliers look for innovative engineering solutions that provide maximum efficiency combined with low cost. Parker has designed and supplied specialized actuators optimized to stringent performance requirements. The highly efficient rack-and-pinion gearing at the heart of actuator systems provides high power at low rotational speeds. The actuator is capable of driving the maximum number of solar panels under high wind conditions at a slow speed, allowing precision tracking of the sun. The low maintenance, stand- alone system has an integrated fluid reservoir and offers variable drive speeds if multiple pumps are used Steel Industry This world of extremes presents many unique challenges for equipment used for automating critical processes. Parker hydraulic rotary actuators are a vital part of the steel making industry. Unlike a cylinder, the hydraulic rotary actuator is completely enclosed in a rugged steel housing that protects critical working elements from the harsh and contaminated environment of the mill. In addition to a broad, standard line of small actuators suitable for a variety of tasks, Parker’s large precision units supply millions of Boomslewer and in-lbs of controlling torque to tip Large Actuators and control the ladles of molten The world’s largest hydraulic a self-contained reservoir, hydraulic steel.

The actuator has import processes. Marine and Submerged Applications - Water Control Management The Pneumatic Division of Parker Hannifin has furnished specialty actuators for submerged and marine operations for 45 years. It supplies the US Military with actuators to automate valves, deploy antennas, open and close torpedo doors and hatches, and to perform other tasks. Most of these actuators are custom- made to meet specific requirements. Our largest Tork-Mor vane-type actuator operates the pool gates for the Shamu Seaworld attraction. Our HTR and M Series units are used in gantry and boom actuation functions on ships. Our actuators also are built into steering systems on surface ships and into vane control on High Tech Applications submersibles.
