Disassembly and Rebuild Procedure

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.

  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
  • Teardown: Every valve is disassembled for internal inspection.
  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance specs.
