Common Questions

Frequently Asked Questions

What is your typical repair turnaround time?
Standard repair turnaround is typically 7-10 business days. Expedited service may be available depending on workload for urgent production downtime situations.
Do you repair discontinued or legacy models?
Yes. We specialize in repairing discontinued servo valves and drives that are 10-30 years old where OEM support is no longer available.
What is included in your 1-year warranty?
All repairs include a 1-year warranty covering parts and workmanship. Standard exclusions apply for contamination, improper installation, line-side faults, and out-of-spec operation.
Can you repair valves/drives for equipment not listed?
Yes. If your equipment or brand isn't listed, contact us with model details. We repair servo valves and drives across a wide range of industries and manufacturers — send model details to confirm coverage.
Do you offer field service or only bench repair?
Bench repair is our standard service where you ship the unit to us. Bench repair only — ship the unit in. We don't run a field-service team.
How much does servo valve repair cost vs. replacement?
Repair is often substantially less than new OEM replacement, especially on discontinued models. Request a quote for your specific part. Exact cost depends on model, failure type, and parts availability. Request a quote for specific pricing.
