Self-contained electro-hydraulic actuator for ATEX Zone 1
Self-contained electro-hydraulic actuator for ATEX Zone 1
(OP)
I'm looking for a self-contained electro-hydraulic actuator for an ATEX Zone 1 application. I've found one possibility from Rexa, but I'm looking for anyone else with a similar product. Approx stroke 8", approx force 100kN, transit time approx 10 seconds.
Any ideas? I've tried Google and the usual suspects like Moog and Rexroth on the net but haven't found anything.

The application is a gas turbine IGV positioner, so it is fairly arduous duty. Reliability is paramount. We have a possibility of tying a regular hydraulic servo in to the turbine's existing hydraulic system, but the costs look pretty high to pursue this. The OEM-fitted actuator is a pneumatic positioner, and it has neither the operating speed nor the accuracy that we would like. I'm shying away from pure electric types using screw type mechanisms from a reliability point of view, but based on gut feel and out-of-date experience. How do current all-electric types fair in high temperature, continuous modulating service? My experience has been that they are inferior to hydraulic, but I'm aware that it is an improving technology.
