502 Straight Purge Flow Control

The 502 Series purges are designed for use with high purity gases to ensure system integrity during breakdown of components or during gas source changes. Purges provide safety by preventing the release of toxic or corrosive gases into the workplace when changing cylinders, corrosion resistance by preventing corrosive or halogen gases from coming into contact with atmospheric moisture, and purity by preventing air from infiltrating high purity systems at the time of cylinder change.
