How We Rebuild This Valve

Every MOOG 78-101? gets a controlled teardown on our bench. We document condition, replace what’s needed, and reassemble to proper operating condition.

  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • Teardown: Every valve is disassembled for internal inspection.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance specs.

Leak and Performance Testing

With thirteen in-house test stands 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 operational testing verifies proper functionality.

Technical Specifications

Every MOOG 78-101? we service is tested under operating environments. Our diagnostics verify performance against published specifications. Specification sheets and Technical diagrams are available for purchase upon request.

Stock Availability

With an extensive stock of 17,000+ valves, we can often provide faster turnaround by sourcing parts in-house rather than waiting on OEM lead times.
