Rebuild Steps

The process begins with disassembly and visual evaluation. We then clean, replace worn pieces, and reassemble the valve to restore its function.

  • 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.
  • Final Performance Verification: After reassembly, each valve is bench-tested against published performance specifications.
  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.

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.
