Product catalog summary
Overview
ASCO Numatics offers a range of solenoid valves designed for fluid isolation in analytical and medical technology. The Series 068 flapper valves utilize advanced flapper technology to ensure high reliability and safety when handling aggressive fluids.

Fluid Isolation Technologies
ASCO Numatics provides six fluid isolation technologies: rocker, diaphragm, lever, pinch, bellows, and flapper mechanisms. The flapper mechanism is highlighted for its ability to achieve high pressure rates without the pump effect, making it suitable for sensitive applications.

Flapper Technology Features
  • Excludes particulate contamination from moving parts.
  • Minimizes heat transfer from the electromagnetic control system into the fluid.
  • Ensures high reliability with aggressive fluids.
  • Mechanical separation between fluid and control mechanism.

Benefits of Flapper Valves
  • Low power consumption (up to 1.5 watts with power-save connector).
  • Low heat transfer into the fluid.
  • High pressure range (up to 10 bar).
  • No pump effect.
  • Easy-to-flush internal cavity and good self-draining capability.
  • High-quality materials (PEEK and FFPM/FPM/EPDM).
  • Long service life and various electrical connection options.

Technical Specifications
  • Suitable for neutral or aggressive liquids and gases.
  • Pressure range: -0.9 to 10 bar.
  • Orifice size: 0.8 mm to 4 mm.
  • Power consumption: 4 Watts (1.5 W with power-save connector).

Applications
These valves are ideal for equipment requiring stringent sterility and process safety, such as analyzers, blood purification equipment, chromatographs, dosing systems, gas mixers, micro-reactors, and pipetting workstations.

ASCO Numatics Fluid isolation with flapper technology Mechanical separation between the fluid handled and the valve’s control mechanism is one of the most essential features required for the sensitive applications of analytical and medical technology. Flapper technology is among the most sophisticated and safest solutions for fluid isolation. Due to its specific characteristics, relatively high pressure rates are achieved - whilst the valve’s pump effect is eliminated. ASCO Numatics offers 6 different fluid isolation technologies. They are designed to: –– exclude particulate contamination caused...

Flapper valves-3

Series 068 flapper valves Series 068 fluid isolation solenoid valves with flapper mechanism are suitable for use with neutral or aggressive liquids and gases. Fluid contamination is prevented by the fluid isolation design and the use of high-quality materials (PEEK and FFPM/FPM/EPDM). The special flapper mechanism allows high pressures (up to 10 bar) to be achieved at large orifice sizes (0.8 mm to 4 mm). The use of a power-save connector lowers the holding power down to 2.5 Watts (or down to 1.5 Watts), thus minimising the heat transfer into the fluid. Your benefits –– Low power consumption...
