LQX12 - 12 mm Miniature Diaphragm Isolation Valve

*PRODUCT IMAGE IS REPRESENTATIVE PROVIDED BY THE MANUFACTURER. DO NOT MAKE BUYING DECISIONS SOLEY BASED ON THE IMAGE. PLEASE VERIFY SPECIFICATIONS MEET YOUR REQUIREMENTS.

Parker’s LQX12 is a high-performance 2-way and 3-way universal isolated diaphragm valve. This highly flexible design is 12 mm wide and offers two different elastomer options. The LQX12 valve supports the pressure and flow requirements needed by today’s analytical, bio-analytical, and clinical diagnostic OEMs.

Markets:
• Clinical Diagnostics
• Analytical Chemistry

Features/Benefits:
• EPDM or FFKM elastomers for particulate tolerance and reliability in a wide range of liquid media
• 100% tested leak rate ensures a tight seal on every valve
• 12 mm width allows for reduced system sizes and efficient packaging
• Designed to be manifold mounted side-to-side on 12 mm centers
• Low internal unswept volume to minimize carryover and cross-contamination
• Secure electrical termination to female connectors with friction-locked latching electrical connection
• Optional ¼ - 28 ported sub-base for standalone operation or testing
• RoHS compliant

Applications:
• Clinical Diagnostics Instrumentation
• Hematology
• Automated Slide Stainers
• DNA/RNA Synthesis
• Environmental Analyzers
• VOC/TOC
