Valves

Valves

Micropumps form the tangible heart of our performance. A performance that is extended by necessary components, such as valves, to achieve full system functionality.

That is why we offer these in addition to our various micropumps. Like for example our own developed passive check valves. Additionally, we have three partners that offer you a variety of active valves:

  • BMT, manufactured by Takasago from Japan.
  • memetis valves by themselves or in combination with the evaluation set coming from memetis
  • Staiger is the newest addition to our portfolio

With these valves you can switch your microfluidic system at will, as well as quickly and easily set up. Add the advantage of active monitoring and make regulation possible. Thus, you can quickly and easily make your microfluidic system intelligent and miniaturized.

Memetis 2/2-way bistable valve

The ultracompact 2/2-way media isolated bistable (BV1101) from memetis enables complex fluidic systems with very low power consumption. It is perfectly suitable for fluidics in life science and other small but complex fluidic applications. We cooperate directly with memetis GmbH.

Additional evaluation kit is available.

Technical data:

  • 2/2-way, bistable
  • also available as normally closed
  • Actuator: shape memory alloy
  • dimension: 20 x 5 x 10.1 mm
  • material: PEEK Housing, Silicone Membrane,
  • power consumption: 0.17 J per switching operation
  • switching time: 0.04 s / 0.13 s @1 bar

Staiger 2/2-way Normally-Closed valve

Small, low-wear and ultra-fast

For precise dosing smallest amounts of gases and liquids. It is possible to achieve ultra-fast switching operations and high dosing accuracy.
In addition, the spider valves by Staiger stand out by being small in size and low in weight.
All of them are 100% calibrated which leads to a high repeatability and long-term stability.

Technical data:

  • available as 2/2-way normally-closed (nc)  and 3/2 way
  • Actuator: magnet
  • size: 7 mm
  • operating temperature range: 5 – 50°C
  • Input voltage: 5 V
  • Sealing material: FKM, other material possible
  • switching time: < 1 ms
  • Media: air and water

mp-cv

The passive check valve prevents the medium from flowing back when the pump is switched off.

Technical data:

  • Dimensions: 21 mm x 5.5 mm (length x wrench size)
  • Material: Silicone, Stainless Steel
  • Fluidic connections: Hose olive, length: 5.6 mm for hose with internal diameter: 1.3 mm
  • Cracking pressure typically < 35 mbar Max. Back pressure 500 mbar
  • Leakage rate <20 µl/h for DI water (at 500 mbar)
This component part the mp-cv was produced by Bartels Mikrotechnik for the application in the field of microfluidics together with the mp6 micropump in microtechnology
