Repair Process

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.

  • Teardown: Every valve is disassembled for internal inspection.
  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.

Hydraulic Testing Process

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.
