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.
- If the upper actuator (red) is energized and thus heated, it presses the switching element down against the second magnet.
- 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.
