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.

  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance specs.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
  • Teardown: Every valve is disassembled for internal inspection.

Testing and Bench Verification

With our 13-stand test facility and a Hagenbush proportional valve system, we verify flow curves, hysteresis, frequency response, and more. Performance reports and graphs are available for purchase on request. Our pre-shipment testing verifies consistent performance.

Maintenance Tips

  • Perform fluid analysis to detect contamination early and prevent system damage.
  • Replace inline filters according to maintenance schedules to maintain proper flow rates.
  • Store spare MOOG 52-512B valves in a clean, dry environment to prevent corrosion and contamination.
