Modern hydraulic systems rely heavily on proportional and servo technology for precision, speed, and reliability—but when problems arise, troubleshooting can be complex and time-consuming. This 1-hour technical webinar provides a practical, systematic approach to diagnosing and resolving common issues with proportional, servo-proportional, and servo valves and their associated electronic amplifiers.

Participants will learn how to distinguish between hydraulic, mechanical, and electrical faults, interpret valve and amplifier signals, and identify root causes of performance problems such as instability, drift, slow response, overheating, noise, and erratic motion. The session will also cover proper setup checks, feedback devices, wiring considerations, contamination effects, and amplifier adjustments.

Through real-world examples and troubleshooting scenarios, this webinar bridges the gap between theory and field practice, giving attendees actionable techniques they can apply immediately to reduce downtime and improve system performance.
