Valves eliminate need for tubing sets to connect individual valves

Boonton, NJ (July 27, 2012) – Bio-Chem Valve™ Flow Selection Valves reduce the number of connections and potential leak points in flow mixing and selection for highly aggressive and high purity fluid applications. Flow Selection Valves combine multiple valve actuators into a single compact unit around a central block, allowing mixing or selection of any combination of between two and eight individual source streams.

Bio-Chem Fluidics’ Flow Selection Valves for highly aggressive and high purity applications.

Flow Selection Valves use a flexible diaphragm that isolates the solenoid actuator from the fluid path. All wetted parts are constructed from highly inert, non-metallic materials such as PTFE or PEEK. Flow Selection Valves are available in a range of orifice sizes from 0.032” to 0.125”, and power ratings from two to eight watts.

Valves feature a radial manifold block, eliminating the differences in flow path length and timing found in linear manifolds. Each solenoid actuator is individually adjusted by the manufacturer to ensure equal flow rates at the same pressure.

Bio-Chem Fluidics’ valves offer lower pressure drop than conventional mixing valves

Boonton, NJ (July 11, 2011) – Delivering unobstructed, inert fluid paths with high flow rates and low dead volumes, Bio-Chem Fluidics offers the RV-Series of Electric Rotary Valves.  The series features three different models for easy integration into OEM systems.

Bio-Chem Fluidics’ electric rotary valves for OEM systems.

Designed for applications such as sample collection, loop injection or flow path selection, the series of valves provides a lower pressure drop than conventional solenoid mixing valves.  Each model’s ¼”- 28 UNF fluid port connections and flow configurations were designed to match the industry standard most commonly found in existing systems. All valves use a unique PTFE fluid path for maximum compatibility with aggressive solvents.

The RV-Series includes three different models to match customers’ needs.  The most basic model, the RV-E, includes only the valve head assembly for use with a system’s preexisting stepper motors.  The RV-SN includes its own two-phase, hybrid stepper motor, and the RV-SC features the same stepper motor with an intelligent motor controller and driver.
