Application: Dual ARV Modules

Parker Gen II R-max ™ Stream Switching System

Application: Dual ARV Modules

The Parker Gen II R-max ™ stream selection system can be configured for delivering process stream to multiple Gas Chromatograph inject valves while maintaining the atmospheric reference essential for consistent sample injection. The use of dual ARV (Atmospheric Reference Vent) modules allows the process analyzer engineer to measure a single stream on separate column trains (i.e. parallel chromatography) or use different GC detectors for analyzing specific compound functional groups (i.e. sulfur, halogens, etc.). The use of dual GC modules demonstrates Parker Gen II R-max ™ valve flexibility and broad application scope for multiple stream selections.

Dual ARV Modules Example 1

All valves are in the “off” position. The system is “open” to atmospheric vent.

Dual ARV Modules Example 2

Stream 1 and ARV Module A are in the “on” position. Sample Inject Valve A is receiving the sample from Stream 1 and is returned to the Low Pressure header through ARV Module A.
