REXA is a custom-designed actuator that offers reliable control of any valve or gate service. It employs Electraulic technology, operating like an electric actuator that employs a hydraulic transmission without the use of an actively pressurized reservoir system. This technology eliminates the maintenance burdens, liability concerns and high costs of ownership common to other hydraulic systems. The result is a hydraulically driven actuator designed to modulate accurately and reliably over long periods of time without attention, reducing cost of ownership. 508-584-1199; www.rexa.com; Booth 6823.
