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.

  • 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.
  • 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.

Diagnostic Testing

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 proper functionality.
