Description
The TitanEX platform has been specifically designed from the ground up for low-pressure (<125 psi) medical, analytical, biotechnology, and industrial applications. This innovative product line from Rheodyne is available as a:

• Six-Position, Seven-Port Stream Selector
• Two-Position, Six-Port Double Three-Way Switching Valve
• Two-Position, Six-Port Switching Valve
• Ten-Port, Eleven-Position Stream Selector

TitanEX implements advanced polymeric wear surfaces, an exclusive tubing connection system, and uses Rheodyne's absolute position feedback. These features provide a high-performance fluid management platform for OEM customers' ultra-high duty cycle applications in a low-cost, small footprint package.

Applications
Typical applications include:

• Process Control: Process stream sampling, FIA sample injection, reagent/calibrant selection
• Industrial: Manifold solenoid replacement, fluid switching/fluid selection
• Biotechnology: Fermentor sampling, HTP screening reagent addition, automated chemical dispensing
• Scientific Instrumentation: Ultra-high purity water sampling, TOC reagent selection, HPLC solvent selection, post-column fraction collection.

Long-Life Polymer Sealing Surfaces: Long life is a cornerstone of the TitanEX platform. During the past five years, component lifetime has become increasingly important as duty cycle regimes have increased. TitanEx's use of polymer wear surfaces was dictated by OEM's need for maximum longevity and maintenance-free operation. The result is a ceramic-based fluid platform qualified to millions of actuations.

TitanEX can be fitted with a range of long-life, biochemically and chemically inert polymer surfaces.

Tubing Connection System: Our customers told us that traditional low-pressure tubing connections were less than ideal. Whether tubing was flared or ferruled, poor quality connections resulted. We found a better approach. The TitanEX tubing connection system is unique and fittingless — all the parts are internal to the valve. The design reduces the tubing/valve interface to a simple finger-tight operation that requires no tools. Simply insert the tubing into ports, tighten the spanner nut, and you're done. The connection system will accommodate 1/8" and 1/16th tubing.

Random Access and Multiposition Capability: Manifold solenoids are frequent solutions to the problem of randomly accessing different streams/reagents/samples; however this solution becomes very expensive as the number of lines increase and the pressures rise to 100 psi and above. The TitanEX Selector was benchmarked to solve this problematic technical and cost challenge. Depending on the application, a single random-access TitanEX selector can replace a manifold and solenoids for less than half the cost. In addition, TitanEX's 1 mm ID and smaller geometry and shear-face design provides equipment manufacturers with a zero dead volume design.

Advanced Composites Mean No Maintenance: The valve body and internal wear components make extensive use of modern material science by employing advanced composite polymers throughout. These highly inert and wear-resistant materials allow the valve to be actuated over the full operating temperature range without maintenance during its lifetime.

Available with Integrated Driver Board: The optional driver board integrates with the TitanEX platform to provide the added functionality of motor drive and valve control without significantly affecting the small footprint of this multiposition valve. Customers need to provide only 24" VDC power and 4-line BCD signals for random access actuation with position feedback. The benefit to OEM customers is clear —elimination of internal board and firmware development means shorter product development cycles and reduced time-to-market.
