We can often prioritize urgent jobs. Note it on your request form and we’ll let you know what’s possible.

We recommend sending pictures, especially if the model number is unclear or there is visible damage.

Send the unit in whatever condition it’s in. We clean everything during teardown before inspection begins.

If the main housing or board is intact, repair is usually the better option. We can restore most units to working condition with tested parts.

We confirm next steps with you if a unit can’t be rebuilt. No work proceeds without your approval.

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.

  • Complete Disassembly: The unit is disassembled and all parts are laid out for individual inspection.
  • 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.
  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.

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 functional testing verifies proper functionality.
