Directional-control valves are common in pneumatic systems. They control compressed-air flow to cylinders, rotary actuators, grippers, and other mechanisms in packaging, handling, assembly, and ...

The valves, which can move from fully-open to fully-closed in as little as 30 msec, reportedly can fit in a fraction of the package space ordinarily needed for comparably-rated valves using a linear ...

Piezo elements are electromechanical transducers that convert mechanical forces (pressure, tensile stress or acceleration) into voltages. The inverse piezoelectric effect, precisely the opposite, ...
