Dynamic Testing

Electro-hydraulic servo valves are generally used in systems which require accurate, highly dynamic response. With the servo valve being the "heart" of these systems, its response characteristics are critical to overall system performance.

Unless otherwise requested by customer, SL-T will provide engineering upgrades and new OEM parts will be used during the process.
