ASCO™ Series 458 Rocker Isolation Valves
asco-series-458-peek
The ASCO’s patented Series 458 rocker isolation valves are designed for use with the neutral or highly aggressive liquids found in analytical instrumentation.
Hermetic separation of the control mechanism prevents particulate contamination caused by friction of moving parts, assuring maximum purity of liquid samples. A special rocker mechanism prevents heat transfer to the fluid, eliminates the sticking effect of the valve seat, and significantly reduces erratic liquid flow. Typical applications include in vitro diagnostics, DNA sequencing, hematology, and surgical fluid management.

Features

  • Designed for corrosive media that can attack valves designed for general service duty
  • Excellent self-draining capability and easy-to-flush low-volume internal cavity make these valves ideal in applications where cross-contamination must be minimized
  • Rocker design significantly reduces erratic flow caused by pumping action in poppet style valves
  • Standard built-in manual operator for testing or troubleshooting
  • Meets all relevant CE directives, and is RoHS-compliant for lead-free applications
