Questions

Rexroth Valve Repair FAQs

What if you dont have my specific Rexroth valve in stock?

While we maintain an inventory of over 19,000 hydraulic valves, if we dont have your specific Rexroth model in stock, we can act as a broker to source it for you. Our industry relationships allow us to locate hard-to-find and discontinued Rexroth valves from verified suppliers worldwide.

Do you offer exchange programs for Rexroth valves?

We maintain a large inventory of rebuilt Rexroth valves. After evaluation, if your unit is not economical to repair or if you need faster turnaround, we can discuss purchasing a rebuilt unit from stock. Core credit may be available based on your unit's condition and parts value.

Can you repair Rexroth 4WE series valves?

Yes. We repair the complete Rexroth 4WE series including 4WE6, 4WE10, and other NG6 through NG32 proportional directional control valves. Our technicians rebuild spool assemblies, replace coils, and calibrate control electronics.

How long does a Rexroth valve repair take?

Turnaround depends on part availability, severity of damage, and whether we have replacement components in stock. As an independent service provider, we typically offer faster turnaround than manufacturer service. Contact us for a timeframe estimate on your specific valve. Rush service is available for time-sensitive situations.

What warranty do you provide on Rexroth valve repairs?

All Rexroth valve repairs include a 1-year warranty covering parts and workmanship. This warranty ensures confidence in the quality and reliability of our repair services.

Can you repair discontinued Rexroth valve models?

Yes. NC Servo maintains parts inventory and technical knowledge for many discontinued Rexroth valve models that the manufacturer no longer supports. We can often repair or rebuild valves that OEMs consider obsolete.

What is the difference between Bosch, Rexroth, and Bosch Rexroth?

Rexroth was acquired by Bosch and now operates as Bosch Rexroth. Current products are branded "Bosch Rexroth" while older equipment may be labeled "Rexroth" or "Mannesmann Rexroth." We service all Rexroth-branded hydraulic valves regardless of branding generation. For Bosch-branded valves, see our Bosch valve page. For combined Bosch Rexroth systems, visit our Bosch Rexroth page.

Do you service Indramat servo drives?

Yes, we repair Indramat servo drives. Indramat was acquired by Rexroth and is now part of Bosch Rexroth's drive systems division. For Indramat drive repair services, visit our dedicated Indramat servo drive repair page.
