Frequently Asked Questions

Valve Refurbishment Steps

Our experienced team completely disassembles each valve to assess internal wear conditions. After ultrasonic cleaning, we install high-grade replacement components and reassemble to exacting standards.

• Meticulous Cleaning: All parts undergo an ultrasonic cleaning process to remove contaminants before inspection.
• Rigorous Testing: The reassembled unit undergoes rigorous leak and pressure testing to verify it performs to specification.
• Thorough Decontamination: Every component is put through a deep cleaning process to remove grime and buildup.
• Final Performance Verification: After reassembly, each valve undergoes bench-testing to ensure it meets or exceeds OEM performance specifications.

Troubleshooting & Verification

With our 13-stand test facility 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.

Maintenance Tips

• Replace inline filters according to maintenance schedules to maintain proper flow rates.
• Check valve alignment carefully to prevent undue stress on internal components.
