Stream switching system

simplifies gas and liquid control

Parker’s Gen II R-max system for gas and liquid analytical applications is based on the proven technology of its popular 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.

Designed to control both gases and liquids in analytical systems ranging from vacuum to 34 bar, the Gen II R-max only requires 65 PSIG (5 bar) actuating air pressure. The new system was engineered with a focus on improved product reliability and reduced cost-of-ownership. It is designed for use in the analytical, oil and gas, petrochemical, and chemical industries.

The Gen II R-max utilises state-of-the-art 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 Gen II R-max system features an internal self-purging outlet header that eliminates the need for an additional outlet loop.

Features of Parker's Gen II R-max stream switching system include a captured vent that provides a low pressure header to separate the sample stream from the actuation air, thus preventing cross contamination of the sample stream. An enhanced position indicator also displays a yellow band against a black background, to provide easier recognition of valve actuation.

The Gen II R-max stream switching system retains all the advantages of its R-max predecessor, such as the use of surface mount technology that enables users to add additional streams or functions very easily, and the modular valve design that helps to simplify field maintenance and reduce system downtime. Overall system efficiency is maximised by the system’s low internal volume and low dead volume, which reduces purge time.

The Gen II R-max, like the R-max, is also available on the Parker IntraFlow ISA/ANSI–SP-76 compliant (NeSSI) modular surface mount system. IntraFlow substrate fittings have been developed specifically for analytical, laboratory and other complex general-purpose instrumentation flow control systems. IntraFlow fittings provide maximum flexibility with minimum space requirements. All flow paths, regardless of direction, are maintained on a single plane within the system, as no lower level manifold blocks are required. Every feature of the Gen II R-max system is available within the IntraFlow product line.
