IDEX Manual and Actuated Selection Valves

Selection valves enable discrete connections among multiple system liquids (mobile phase, reagents, buffers) by means of a common port (inlet or outlet) connected to a number of different reciprocal ports. In Diagnostic or Sequencing applications, the selection valve alternates between different reagents or sample streams. Selection valves also enable fractionation for multiple sample analyses.

Numerous configurations exist among selection valves (e.g., 6-position 7-port, or 10-position 11-port), but these valves always operate between more than two positions. The ports are usually spaced radially, or outward in some manner around the center port of the stator.

IDEX Manual Selection Valves

Our unique Six-Position Selector Valves enable discrete connections among multiple system liquids by means of a common central port (inlet or outlet) connected to a number of different reciprocal ports. In Chromatography, these valves can be used for column switching, fraction collection, or to select between six different mobile phases. In diagnostic or sequencing applications the selection valve alternates between different reagents or sample streams. Bulkhead Switching Valves utilize the mounting bracket M-615-1 found in Valve Accessories.

IDEX Actuated Selection Valves

MX Series II™ actuated valves are designed to be added to your existing instrument or to work optimally with stand-alone lab configurations. Our valves can be controlled remotely or operated manually using the push-button front panel with LED position indicator. They easily connect to your instrument or PC through contact closure, BCD, serial port, or USB. Commands can be sent to the MX valves using your chromatography software or the included proprietary software for timed-events programmability. These valves are manufactured to be utilized for a multitude of applications for ultra-high pressure, high pressure, and low pressure applications.
