Frequently Asked Questions

Yes. Every unit goes through diagnostic testing and we provide an assessment before moving forward.

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

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

Even if the tag is worn off, we can often match the unit based on shape, size, and internal configuration.

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

Rebuild Steps

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.

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

Leak and Performance Testing

We carry out full diagnostics on every valve, including flow gain, leakage, pressure shift, and frequency testing. Our test facility supports performance logging and report generation. Our operational testing verifies consistent performance.
