Parker Hannifin Gen II R-max stream switching system for gas and liquid analytical applications

A multifunctional stream switching system for process analytical instrumentation that is capable of integrating stream selection and filtering functions into one compact, modular assembly is available from the Instrumentation Products Division of Parker Hannifin.

The Gen II R-max system for gas and liquid analytical applications is based on the technology of its R-max stream switching system and incorporates numerous enhancements to further improve application flexibility, process integrity and serviceability. Backward compatibility allows the features of the Gen II R-max to be installed on existing R-max units very easily and quickly.

The system offers the flexibility of delivering multiple sample streams to an analytical system with a single, small footprint assembly. Other advantages include the system’s modular design, which simplifies configuration and maintenance, and the availability of normally closed, normally open and single 3-way configurations.

Enhancements include a captured vent that prevents cross contamination, an improved position indicator for quick recognition of valve actuation, easier removal of cartridges for maintenance, and an atmospheric reference vent module.

Designed to control both gases and liquids in analytical systems ranging from vacuum to 500 psig (34 bar), the system only requires 65 psig (5 bar) actuating air pressure.

The system uses surface mount technology to reduce leak paths, internal volume and dead volume. With surface mounting, system components can be easily removed and replaced without breaking process connections. In addition, the system features an internal self-purging outlet header that eliminates the need for an additional outlet loop.
