Frequently Asked Questions

Service Procedure

Each valve undergoes a complete teardown process to expose wear patterns and buildup. After cleaning every surface thoroughly, we replace damaged parts and reassemble the unit to exact specifications.

• Final Performance Verification: After reassembly, each valve undergoes bench-testing to ensure it meets or exceeds OEM performance specifications.
• 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.
• Complete Disassembly: The unit is fully disassembled, and all parts are laid out for individual inspection.

Our Testing Process

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 performance testing ensures guaranteed reliability.

Maintenance Tips

• Conduct thorough visual inspections for wear or leaks during routine maintenance.
• Conduct visual inspections for wear or leaks.
• Check valve alignment carefully to prevent undue stress on internal components.
