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.

• In-House Parts Sourcing: Many repairs use reliable components sourced from our extensive inventory of existing units.
• Final Performance Verification: After reassembly, each valve undergoes bench-testing to ensure it meets or exceeds OEM performance specifications.
• Thorough Decontamination: Every component is put through a deep cleaning process to remove grime and buildup.
• Meticulous Cleaning: All parts undergo an ultrasonic cleaning process to remove contaminants before inspection.

Testing & Diagnostics

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.
