Frequently Asked Questions

Valve Refurbishment Steps

We disassemble every valve systematically, inspect it inside and out, and clean all moving parts meticulously. Components that fail inspection are replaced before the valve is rebuilt and tested.

  • Meticulous Cleaning: All parts undergo an ultrasonic cleaning process to remove contaminants before inspection.
  • In-House Parts Sourcing: Many repairs use reliable components sourced from our extensive inventory of existing units.
  • 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.

Quality Check Procedures

We carry out complete diagnostics, including flow gain, leakage, pressure shift, and frequency testing, on every valve. Our test facility supports detailed performance logging and comprehensive report generation for quality assurance. Our pre-shipment testing ensures guaranteed reliability.

Maintenance Tips

  • Replace inline filters per maintenance schedules.
  • Conduct thorough visual inspections for wear or leaks during routine maintenance.
