The bistable micro valve

Perfect for mobile applications where power consumption needs to be kept to a minimum

The bistable micro valve

The bistable micro valve from memetis is a 2/2-way valve and media separated. The special feature of this valve is the fact that power is only needed to switch between the open and closed state and this switching energy is very low. The miniature valve remains open or closed without requiring additional energy. This makes mobile applications with valves possible and even battery operation is feasible. The valve can be used in a wide variety of applications, for example in the life sciences sector. All components in contact with the liquid are made of biocompatible material and the switching of the valve is silent, so that the valve can also be used close to the patient and the switching of the valve is not perceived as disturbing.

The ultra-compact size enables innovative fluidic solutions. A width of only 5 mm simplifies the integration of many valves in the smallest installation space. In addition, the valve has a very small internal volume of less than 4 ┬Ál. The inlet and outlet of the valve are located on the bottom side and are equipped with O-rings for sealing.

The advantages of the bistable valve at a glance:

  • requires only 75 mJ of energy for switching
  • ultra compact
  • powerful with switching pressures up to 1 bar
  • media separated
  • low internal volume
  • easy electrical and mechanical integration
  • biocompatible materials
  • for gases and liquids
  • up to 10 million switching cycles
  • noiseless operation
  • customizable thanks to patented layer structure

Functionality

Innovative shape memory actuator technology is built into memetis valves. Two actuators made of a shape memory alloy can move a switching element between two magnetic stops.

  1. If the upper actuator (red) is energized and thus heated, it presses the switching element down against the second magnet.
  2. The magnet holds the switching element in place so that no further current is required to maintain the closed state. As a result, the switching element presses a ball onto the valve opening and the valve is closed.

Between the ball and the valve opening is an elastic membrane that prevents fluids from entering the actuator portion of the valve. The patented layered structure enables customer-specific adaptability - so specific material requirements can be met.
