ASCO™ Series 202 Preciflow Proportional Valves
The ASCO Series 202 Preciflow solenoid valves are designed to precisely control the flow rates in medical equipment and analytical instrumentation.
They proportionally control the flow of air and inert gases by varying the electrical input signal to the coil. The compact, ultra-reliable valves are suitable for applications such as gas chromatography, mass flow controllers, dental equipment, and blood pressure monitoring instruments.

Features

  • Low hysteresis (< 5%), excellent repeatability (< 3%), and high sensitivity (< 2%) make the valves ideal for high-precision flow control
  • Minimum operating pressure is not required, and the valves are well-suited for vacuum operation
  • Compact frictionless architecture saves valuable space in analytical and medical instrumentation
  • Power consumption as low as 1 W fulfills the most stringent instrument power requirements
  • Meets all relevant CE directives, and is RoHS compliant for applications in lead-free environments
