by | Jul 5, 2012

Parker's LQX 12 family of 12mm diaphragm isolation valves offer metal free wetted paths with EPDM and FFKM versions to meet the needs of your applications.

Product Information

LQX12 is a high-performance two-way normally closed and three-way universal isolated diaphragm valve. This highly flexible design is 12mm wide and offers two different elastomer options. LQX12 supports the pressure and flow requirements needed by today’s analytical, bio-analytical, and clinical diagnostic OEMs.
  • EPDM or FFKM elastomers for particulate tolerance and reliability in a wide range of liquid and gas media
  • 100% tested leakrate ensures a tight seal on every valve
  • Reduced system size with efficient packaging and 12 mm width
  • 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 t0 female connectors with friction locked (latching) electrical connection
  • Optional ¼-28 ported sub-base for standalone operation or testing
