Parker Hydraulic Rotary Actuators

The HUB_rotary_actuator_zm Parker  HUB-Hydraulic Unibody Rotary Actuator Series is designed to perform in the harshest environments with hard coat anodized and hardened alloy steel components. Built with a hard-coat anodized housing and hardened, high-strength alloy steel pinion and racks, this product is ideal for applications where weather can be a factor. The HUB-Hydraulic Unibody Rotry Actuator series is designed with several add-on valve modules for lower overall integration costs, as well as an increase in product performance. Multiple feedback and visual indication options are also available.Add-on valve modules, feedback, & visual indication are available for lower integration costs & increased product performance.

Rack and pinion design provides excellent efficiency characteristics (90-95%) and minimizes HPU Size
Direct mounting design to numerous process valves allows for minimal integration cost
Integrated valve modules options are available for increased performance and reduced plumbing cost
• Cross over vent module – allows for flow between both cylinder ports
• Counter-balance valve module with cross over vent – designed for load holding in both directions
and preventing a run-awayload situation from occurring. Also allows for flow between both cylinder ports.
• D03 Solenoid ready module – manifold block directly mounted to actuator for reduced plumbing and
increase in performance
Numerous linear and positional feedback and visual indication options available
Environmentally rugged for reliable performance in harsh conditions
