Pneumatic Valve Presentation
The R&D we performed over the past two years culminated in this superior design of pneumatic valve construction.
Manufacturing and operational flaws detected in patents US 6,705,347, US 6,799,745, and others, were addressed and
solved in this design. The graph depicts the results of actual tests conducted on a Manufacturer’s Proof of Concept valve,
using a piezo-bimorph element and + VDC in-line with polarity and lower + VDC against the polarity of the bimorph.
The driver is depicts in < Driver> and is being offered for licensing separately. It will be appreciated that the levels of
voltages and the specifications of the bimorph will be determined by the application requirements.
