Rebuild Steps

Once a valve arrives, we tear it down fully, examine key surfaces, and replace worn or damaged parts using components we stock in-house, cutting out OEM lead times.

  • Final Performance Verification: After reassembly, each valve is bench-tested against published performance specifications.
  • Teardown: Every valve is disassembled for internal inspection.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
