Hydraulic rotary actuator series for onshore, offshore fracking applications
Parker Hannifin's Hydraulic Unibody (HUB) series rotary actuator is designed for onshore and offshore fracking applications in the oil and gas industry as well as other applications where rotation is desired in an actuator.
Parker Hannifin’s (NYSE: PH) Hydraulic Unibody (HUB) series rotary actuator is designed for onshore and offshore fracking applications in the oil and gas industry. It is designed for injection equipment used in harsh environmental conditions and has an operating temperature range from -40 to 82 C (-40 to 180 F). Additional applications include automation, mining, water management, forklift handling and storage. The HUB series is built with a hard-coat anodized housing and hardened, high-strength alloy steel pinion and racks. The rack-and-pinion gear design provides greater durability and life than comparable splined gear designs, provides excellent efficiency characteristics (90-95 percent), and minimizes hydraulic power unit (HPU) size. Its one-piece housing is designed to eliminate leak paths and external connections as well as reduce the number of plumbing hoses and fittings. The design allows for mounting directly on numerous process valves, which makes the HUB useful areas with limited space available.
Several add-on valve modules are included such as the crossover vent module, which allows for flow between both cylinder ports. The 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.
