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.

• Complete Disassembly: The unit is fully disassembled, and all parts are laid out for individual inspection.
• 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.
• Thorough Decontamination: Every component is put through a deep cleaning process to remove grime and buildup.

How We Test This Valve

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 pre-shipment testing ensures guaranteed reliability.

Maintenance Tips

• Check valve alignment carefully to prevent undue stress on internal components.
• Replace inline filters according to maintenance schedules to maintain proper flow rates.
• Conduct visual inspections for wear or leaks.
