Frequently Asked Questions

Restoration Workflow

Once a valve arrives, we tear it down fully, examine key surfaces, and replace worn or damaged parts using components we already have on hand, avoiding the long delays you’d get from OEM suppliers.

  • Rigorous Testing: The reassembled unit undergoes rigorous leak and pressure testing to verify it performs to specification.
  • Comprehensive Teardown: Every valve is fully disassembled for a thorough internal inspection.
  • Final Performance Verification: After reassembly, each valve undergoes bench-testing to ensure it meets or exceeds OEM performance specifications.
  • Meticulous Cleaning: All parts undergo an ultrasonic cleaning process to remove contaminants before inspection.
