Experimental study on contamination-induced clamping and visualization of particle ingress and accumulation in threaded cartridge directional valves

Key Points

• Particle ingress and accumulation were successfully visualized under contamination-induced clamping conditions, showing significant findings.
• The study found accelerated particle accumulation rates that reached a threshold of 25% in certain valve designs under specific conditions.
• Observational analysis using controlled clamping techniques enabled in-depth visualization of particle behavior in threaded cartridge valves.
• These results highlight the importance of designing valves to minimize contamination risks, indicating potential performance issues.
