Analytical and Medical Technology

Fluid Isolation Valves have a mechanical separation between the valve internals and the fluid being controlled

There are several different technologies used to create the fluid isolation. The various options are listed below.  All relevant product series are shown at the bottom of the page

Diaphragm Isolation

Series 282 solenoid valves with a diaphragm isolation mechanism are characterised by their compact size, long service life and very low dead volume. They are ideal for controlling aggressive fluids.     

Rocker mechanism

Series 067 fluid isolation solenoid valves with rocker mechanism are characterised by their compact size and hermetic separation between the control mechanism and the fluid. The solenoid valves are ideal for controlling aggressive fluids or applications requiring high fluid purity.

Flapper mechanism

Series 068 fluid isolation solenoid valves 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.

Lever mechanism

Series 283 and 383 fluid isolation valves with lever mechanism can be used at high differential pressures and large flow volumes. Since the offset control mechanism provides for optimal heat dissipation in the electromagnetic component, the valves are suitable for use at high ambient temperatures.

Bellows seal

Series 296 and 396 fluid isolation solenoid valves with bellows seals are characterised by their high functional reliability under harsh conditions and their long service life.

Pinch mechanism

Series 284 and 384 fluid isolation pinch valves are characterised by their uninterrupted flow path (no dead volume) and the long service life of their tubes. The tube's long service life is achieved by the pinch mechanism which is designed to provide a smooth, constant pinch pressure on the tube.
