Eaton Hydraulic Remote Control HRC-30

HRCs (hydraulic remote controls) are available in hand, foot and mechanically operated versions, designed for pilot pressure actuation and control of remotely located directional valves. They are intended for mobile and industrial applications in which hydraulic pilot operation of system components is to be controlled from one operator station. On vehicles, the HRCs are typically
installed in seat armrests or a console.

The 30 design HRCs operate on input flows up to 16 L/min (4.2 USgpm) and pressures up to 110 bar (1600 psi) or 150 bar (2175 psi), dependent on the model and the type of response required for the application. HRCs require input pressures equal to the maximum required output pressures, and preferably a minimum of 10 bar (145 psi) higher to assure fast response. From the input pressure an HRC creates reduced output pressures that vary proportionally with lever or pedal stroke, applying the pressures to main directional valves controlling speed and direction of hydraulic actuators.
