How We Rebuild This Valve

Our team disassembles each valve to assess internal wear. After ultrasonic cleaning, we install replacements and reassemble and verify operation.

  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
  • Final Performance Verification: After reassembly, each valve is bench-tested against published performance specifications.
  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.

Leak and Performance Testing

NC Servo Technology operates over a dozen dedicated flow test stands, including setups for proportional and servo valves. Every valve goes through performance and leak testing using a range of hydraulic fluids like Skydrol and MIL-5606. Our performance testing verifies consistent performance.

Technical Specifications

Every BOSCH 0811-404-258 we service is tested under real-world conditions. Our diagnostics verify performance against published specifications. Technical diagrams and Specification sheets are available for purchase upon request.

Stock Availability
