REXA Xpac actuators feature a self-contained Electraulic™ power module utilizing the patented Flow Match System. This technology allows precise positioning independent of load variation and locks the cylinder in place when no movement is required. Hydraulic flow is generated by an internal positive displacement gear pump driven by a continuous duty motor without limitations on start, stop, or reverse cycles.

REXA Xpac series actuators and drives provide customers with exceptional reliability and solid construction. Electraulic™ Technology combines the simplicity of electric operation, hydraulic power, the dependability of solid-state electronics, and the flexibility of user configured controls. Our proven electro-hydraulic design includes self-contained actuator mounted hydraulics, requiring lower maintenance, and minimal power consumption.

  • Controllability—low deadband, immediate response, high stiffness, 100% modulating duty cycle. It can respond to control signal changes as low as 0.1% (optional to 0.05%).
  • Hydraulic Stability
  • Total Electric Operation— self-contained, discrete movement, consistency of operation. Low power consumption.
  • Low Maintenance— Few moving parts and sealed construction eliminate the need for routine maintenance.
  • Electronic Calibration— Set-up is quick and simple via keypad.
  • Custom Mounting— Rexa’s linear, rotary and drive actuator configurations can be applied to virtually any installation.
  • Failure Position — A known position upon loss of electrical power can be provided by either a mechanical spring or hydraulic actuator.


The microprocessor converts the incoming control signal into a target position and compares it to the current position measured by the feedback sensor.  If the target position and current position deviation exceeds the user-programmed deadband, the microprocessor will initiate motion to adjust actuator position.  A bi-directional gear pump, driven by an electric motor, generates the hydraulic output necessary to move the actuator.  System oil travels from the pump through a series of pilot operated check valves, known as the Flow Matching Valves (FMV’s).  The FMV’s manage oil transfer out of one side of the cylinder and into the other.  This drives the actuator to the target position.  Once the target position is reached the motor and pump stop, and the FMV’s close, hydraulically locking the cylinder in place.  The motor will only turn on again if the signal deviation exceeds the deadband and a position change is required.


Together, We Create Extraordinary Flow Control Solutions To Make The World Better For Everyone.
