502 Tee Purges Flow Control

The 502 Series purges are designed for use with high purity gases to ensure system integrity upon 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. Tee purges are available in two configurations. An inboard purge allows inert gas to enter the system for displacement or cycle purging. An outboard purge permits a process or inert purge gas to safely exit the system. The two tee purge types can be used together in a “block and bleed” configuration to effectively purge any system
