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 ...

Getting a valve out of a vehicle isn’t too hard – it’s putting the new one in that requires more care. A typical commercial vehicle air braking system requires, at minimum, around a dozen core ...

Fittings such as these, for connecting a compressed air line to the spark plug hole for valve support, are available at most auto parts stores. Occasionally it is necessary or desirable to inspect or ...

A single power plant uses hundreds of valves to control almost every aspect of its operation. Valves, in conjunction with a controlling actuator, are used for pollution control, feed water, cooling ...

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