Repair Process

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

  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
  • 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.

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 operational testing verifies proper functionality.
