Disassembly and Rebuild Procedure

We disassemble every valve, inspect it inside and out, and clean all moving parts. Components that fail inspection are swapped out before the valve is rebuilt and tested.

  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • Complete Disassembly: The unit is disassembled and all parts are laid out for individual inspection.
  • Final Performance Verification: After reassembly, each valve is bench-tested against published performance specifications.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.

Hydraulic Testing Process

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 performance testing verifies spec-level operation.
