A typical commercial vehicle air braking system requires, at minimum, around a dozen core pneumatic valves to meet baseline regulatory standards. And these days, there’s no “typical” air brake system ...

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.

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, ...

The article will then look at valve types very briefly before focusing on digital positioners. It will examine the expectations that the user should have with regards to digital positioners, for ...
