Designed for both onshore and offshore fracking applications, the Hydraulic Unibody (HUB) Series rotary actuator operates in injection equipment used in in the harshest environmental conditions. Built with a hard-coat anodized housing and hardened alloy steel pinion and racks, the HUB actuator’s rack-and-pinion gear design provides greater durability and life than comparable splined gear designs. Efficiency characteristics span 90% to 95%. Additionally, the overall design allows for mounting directly on numerous process valves, reducing the amount of bracketry required and minimizing overall package size. Add-on valve modules include a crossover vent module that allows for flow between both cylinder ports, permitting free rotation of the process valve for greater ease of maintenance. A counter-balance valve module with crossover vent is designed for load holding in both directions, preventing run-away loads and allowing for flow between both cylinder ports. The D03 Solenoid ready module provides a manifold block directly mounted to the actuator for reduced plumbing and enhanced performance. Multiple linear and positional feedback and visual indication options are also available. Specifications for the HUB Series Actuators include:
• Output torques @ 3000 psi (207 Bar): 1800 in-lb to 10,000 in-lb
