Rebuild Steps

We rebuild every valve from the inside out: cleaning, inspection, parts replacement, reassembly, and bench testing.

  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
  • Complete Disassembly: The unit is disassembled and all parts are laid out for individual 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.

Testing and Bench Verification

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 performance testing verifies spec-level operation.
