ASCO™ 068 Flapper Solenoid Valve
The ASCO Series 068 flapper isolation solenoid valve is designed for use with neutral or aggressive liquids and gases in analytical and medical systems.
Its excellent self-draining capability and easy-to-flush low-volume internal cavity make the valve ideal in applications where cross-contamination must be minimized. The valve's special flapper mechanism results in no pumping or sticking effect of the valve seat. Typical applications include hematology, chromatography, liquid sample preparation, in-vitro diagnostics, DNA sequencing, and surgical fluid management.

Standards / Regulations


  • Fast response time and exceptional volume control result in higher productivity and more precise measurements
  • Reduced heat transfer between control mechanism and fluid make them ideal for use with heat-sensitive reagents and biological samples
  • Hermetic separation of control mechanism prevents particulate contamination caused by friction of moving parts, assuring maximum purity of liquid samples
  • High-quality materials tested in excess of 10 million cycles
  • Large orifice sizes combined with the special flapper mechanism permit high-pressure operation (up to 116 psi)
  • Available in three mounting options and two electrical configurations to ensure system compatibility
