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.

  • Final Performance Verification: After reassembly, each valve is bench-tested against published performance specifications.
  • 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.
  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
