Alltech SelectPRO ® Automated Switching Valves
• Increase productivity
• Save time with unattended operation
• Available in stainless steel or PEEK
Alltech’s SelectPRO ® valve systems are electronicallycontrolled
instruments. They increase productivity and
save time and money by eliminating repetitive, manual
switching. Now you can automate a wide variety of fluidprocessing
applications such as methods development,
solvent switching, sample preconcentration, and fraction
collection.
SelectPRO ® valve position is always indicated
by a digital display on the front panel. Operation
is easy with manual switching on the front panel
or automated switching with a built-in electronic
communication interface. Automated control through
the communication interface is accomplished by either
level logic (2-position) or four-line BCD (multi-position)
control. All line controls require contact closure or TTL
outputs.
SelectPRO ® Switching Valve Applications
2-Postition, 10-Port: On-line sample enrichment to
decrease total analysis time
2-Channel Selector with By-Pass: Reduce equilibration
time during solvent changeover between two columns
