It does not matter how fast and accurate a control system is if the final element is not up to the same high level of performance. Often due to poor actuation of process final elements and control valves, control system engineers tend to de-tune the system or, even worse, increase control system safety margin. This automatically translates to production loses, poor process stability, and could even lead to process upsets and unexpected shutdowns.
Rexa Electraulic Actution technology combines the power, speed, accuracy, and stiffness of hydraulics into a self-contained Electro-Hydraulic linear and rotary actuators. Rexa’s Electraulic actuator is 100% duty cycle system that does not require any separate hydraulic oil pumps in comparison to conventional hydraulic systems. However, all components are integrated into a single self-contained system that is able to provide the best control response in terms of speed, accuracy, and dead-time with practically no maintenance activities required on the actuator over the 25-years lifetime of the actuator.
