Multiple Sample Streams to One Analyzer

Swagelok’s SSVseries stream selector valve module system delivers a representative samplefrom multiple sample streams to a single analyzer. The modularassemblies are ANSI/ISA 76.00.02 compatible and accommodate multipleprocess streams in a limited amount of space. Each stream is controlledby a double-block and bleed (DBB) module to eliminate cross-contamination and maintain sample integrity. As system requirements change, modules can be addedor removed. The system’s stream selector feature enables an integrated flow loop to streamlinesampling and purging and provide consistent outlet flow. Regardless ofwhich stream is selected, the flowrates of all streams remainconsistent.A vented air gap helps prevent mixing of pneumatic actuatorsupply and system fluid under pressure.Visual and tactile actuation indicators provide confirmation of thesystem’s operation. Color-coded caps are available for easy identification of the process stream. Inlet and outlet connections are 1/8″ female NPT or SwagelokMPC compatible (ANSI/ISA 76.00.02). A  built-in pneumatic actuator provides repetitive shutoff with fewerpotential leak points than conventional systems.
