What Rexa does

REXA, Inc. is a privately held US industrial manufacturer founded in 1981 and headquartered in West Bridgewater, Massachusetts. The company designs and builds Electraulic™ actuators — a proprietary electro-hydraulic technology that combines electric operation, hydraulic power, solid-state electronics, and user-configured control. The flagship product is the XPAC Series 3, offered in Linear (2,000–275,000 lbf thrust, 2–120 inch stroke), Rotary (2,500–1,500,000 in-lbs torque), and Damper Drive configurations, all featuring a self-contained, sealed, closed-loop hydraulic design with no routine fluid maintenance and 7–10 year maintenance intervals.

The core technical differentiator is REXA's patented Flow Matching Valve (FMV) system, which manages hydraulic oil transfer in a double-acting cylinder using a bi-directional gear pump coupled to a DC stepper or AC servo motor. This architecture enables 0.05% dead-band accuracy, sub-0.1% resolution, 50–70 ms deadtime, and 100% duty cycle operation, while eliminating the external hydraulic power units, filters, and oil maintenance that traditional hydraulic systems require. The company is ISO 9001 certified and holds at least one granted US patent on its FMV technology.

REXA sells custom-engineered actuator solutions through a direct enterprise field-sales motion, targeting critical process control applications in oil & gas (upstream, midstream, downstream), metals & mining, water & wastewater, renewable energy (hydroelectric, geothermal), fossil-fuel power, and pulp & paper. Revenue is generated from one-time actuator product sales supplemented by aftermarket support, technical training, a Quick Ship subassembly program, and Total Integrated Solutions that bundle on-site TAR supervision, installation, calibration, and training. The company maintains a global footprint with documented installations across North America, South America, Europe, Africa, Oceania, and Asia, and is currently expanding capacity through a new 110,000 sq ft manufacturing facility in Middleborough, Massachusetts.
