Questions

Bosch Servo Valve Repair FAQs

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

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

Do you offer exchange programs for Bosch valves?

We maintain a large inventory of rebuilt Bosch units. 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 Bosch 0811 404 series valves?

Yes. We repair the complete Bosch 0811 404 series including 0811 404 605, 0811 404 670, 0811 404 184, and other 0811 series proportional directional control valves. Our technicians rebuild spool assemblies, replace coils, and calibrate control electronics.

How long does a Bosch servo valve repair take?

Turnaround depends on part availability, severity of damage, and whether we have replacement components in stock. Contact us for a timeframe estimate on your specific unit. Rush service is available for time-sensitive situations.

What warranty do you provide on Bosch valve repairs?

All Bosch valve repairs include a 1-year warranty covering parts and labor. The warranty applies when the valve is operated within manufacturer specifications. Contact us for warranty terms and conditions.

Can you repair discontinued Bosch valve models?

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

Do you provide test documentation with repairs?

All valves are tested on our hydraulic test stands before shipment. Standard repairs include confirmation that the valve meets specifications. Test graphs and performance curves are available for purchase upon request.

What is the difference between Bosch and Bosch Rexroth valves?

Bosch and Bosch Rexroth are related but distinct product lines. Bosch manufactures proportional valves and directional control valves for mobile and industrial applications. Rexroth (now owned by Bosch as Bosch Rexroth) produces a broader range of hydraulic systems including pumps, motors, and valves. We service both Bosch-branded and Rexroth-branded valves. See our Rexroth valve repair page for Rexroth-specific services.
