ASCO 282-S Series Isolation Valve

Brand: ASCO

The ASCO 282-S Series is a family of miniature diaphragm solenoid isolation valves designed to control acids, bases, and reagents in analytical and medical instruments.

Their low power consumption and larger orifice sizes make these valves ideal for high flow-rate applications such as in-vitro diagnostics, hematology, spectrometry, and water analyzers.
  • Good self-draining capability and low-volume internal cavity minimize cross-contamination
  • Removable and rotatable electrical coils allow for easy installation and worry-free maintenance
  • Adjustable flow restrictor in valve body allows for easy adjustment of media flow-rates from 10%; ? 100%;
  • Meets all relevant CE directives, and is RoHS compliant for lead-free applications
