We currently have a product that, at it's heart, uses a piezo actuator or piezo translator to quickly open & close a valve aperture to emit pulses of gas. The actuator supplier has advised us that their product has been discontinued & I am struggling to find an alternative. All the ones I can see on the market have around 30µm axial movement but we need 200µm movement.
The current actuator is a disc, 50mm diameter, 5mm thick & with a 10mm centre hole. Can anyone suggest any potential suppliers for a replacement part?
