Parker's series 1 family of Miniature PTFE isolation valves provide an inert wetted path ideal for biocompatibility and aggressive liquids.

Product Information

The inert 3 way Series 1 valve has been designed for systems where chemical compatibility is most important. The wetted path is isolated from the solenoid, and only PTFE and borosilicate glass are in contact with the media passing through the valve. Low internal volume and fast response time ensure repeatable, accurate volumes. Valves will operate without any pressure or vacuum. Life cycle rating of 25 million (worst case tested with no performance degradation)
  • Provides unsurpassed chemical compatibility for a wide range of media with wetted parts of only PTFE and borosilicate glass.
  • Low internal volume
  • 100% continuous duty rating in ambient temperatures up to 66C
  • Low power for reduced heat and power consumption
  • Fast response times for accurate, repeatable results
  • Direct acting does not require pressure or vacuum to operate
  • 100% tested tight leak rate provides assurance of a quality seal
  • Provides reliable operation for the life of your instrument

Typical Applications:

Solvent management for Liquid Chromatography
Highly aggressive media dispensing and control
