Testing Valves for Particle Generation - Application Notes

Industry standards continue to push toward cleaner processes, and valves have always been notorious for generating particles. Over many years, Particle Measuring Systems (PMS) has been asked to recommend a particle-free valve for specific processes. PMS has not defined a specific valve or manufacturer that meets particle-free operation, but we have developed guidelines for testing particle contamination generated by valves. This paper will discuss those guidelines.
