Directional-control valves are vital in any pneumatic circuit, directing or blocking airflow to control the speed or sequence of operations. One method of classifying directional-control valves is by ...

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 ...

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 ...

Like so many of the core technologies integral to automated industrial operations—such as motors, drives, and I/O—valves don’t always receive the attention they deserve in the automation arena.

The mass-flow-rate characteristics of high-pressure pneumatic servo valves (HPSVs) have an important effect on the dynamic performance of high-pressure servo systems. However, these characteristics ...

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