Description

2/2-way shape memory alloy diaphragm isolation valve with fluid separation.

By using a Shape Memory Alloy instead of a magnet, the switching process is almost silent and requires only a very low power of 0.3 W. This technology makes the switching process significantly slower compared to solenoid valves, which means that the valves are especially suitable for applications that need to react sensitively to fast flow movements.

The compact design of only 4.0 x 19.0 x 18.4 mm and the flange connection enable extremely compact integration in microfluidic systems.

We can offer this valve as a low-cost valve.

Power supply precautions

  1. Constant power supply recommended.
  2. Operation with 12 VDC power supply or batteries is possible. It is important to insert a resistor between the valve and the power source. (See diagram on the right.)
  3. Failures in operation so may result in damage to the Shape Memory Alloy.
