Frequently Asked Questions

Valve Refurbishment Steps

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 to ensure it meets or exceeds original performance specifications.
  • 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.
  • Rigorous Testing: The reassembled unit undergoes rigorous leak and pressure testing to verify it performs to specification.
