I have been dealing with these guys for Servos (both new and repaired) for years with no issues.
★★★★★
Great experience with NC Servo. I asked for the impossible on a 1 day turnaround and somehow they did it. Friendly and fast. Great experience with all members of the staff that I interacted with.
★★★★★
I've been in industrial hydraulic field service for 30 years. I recently stopped in to drop off an emergency test/repair. The owner took me through the entire operation, introduced me to his techs and spent over an hour with me. I wish I had met him a long time ago... This is an American gem!
★★★★★
Great communication and quick delivery! Item as described, packed well, and arrived on time.

-
Advanced In-House Testing
We operate 13 dedicated test stands, including a Hagenbuch Proportional Test Stand, and use industry-standard fluids like Mobil DTE Lite, MIL-5606, and Skydrol.
-
Transparent & Detailed Results
Every valve undergoes rigorous testing. Optional performance graphs and detailed failure analyses are available for every unit we inspect.
-
Legacy & Obsolete Part Expertise
We support discontinued and hard-to-find models most shops can't handle. Standard, expedited, and 24-hour rush services are available.
Advanced Digital Protocol Servicing
Modern systems rely on complex digital communication. We specialize in servicing valves with integrated electronics that use protocols like CANbus, PROFIBUS, and EtherCAT. Our process is designed to protect your unique operational parameters, ensuring a seamless return to service.
Before any work begins, we carefully extract and save your valve's specific program. After the repair, we test the hardware against factory defaults to guarantee its mechanical and electronic integrity. Finally, we reload your original program, ensuring the valve is returned ready for immediate, plug-and-play integration into your system—no reprogramming required.
