Frequently Asked Questions

Service Procedure

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.
  • Final Performance Verification: After reassembly, each valve is bench-tested to ensure it meets or exceeds original performance specifications.
  • In-House Parts Sourcing: Many repairs use reliable components sourced from our extensive inventory of existing units.
  • Meticulous Cleaning: All parts undergo an ultrasonic cleaning process to remove contaminants before inspection.

Diagnostic Evaluation

With over a dozen dedicated flow test stands and a Hagenbush proportional valve system, we verify flow curves, hysteresis, frequency response, and additional critical parameters. On request, comprehensive performance reports and detailed graphs are available for purchase. Our functional testing ensures guaranteed reliability.
