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 ...

Compressible fluid flow through control valves will inevitably cause some form of flow-induced vibration in the fluid system. Identifying the type and cause of the vibration requires detective work.

Learning the basics can ease loop tuning frustration and ensure stability. During plant operations, it seems that tuning control loops is an ongoing task, which can be a continual frustration to ...

Filters, regulators, and lubricators (FRLs) are the unsung heroes of pneumatics. Although not as glamorous as the valves, manifolds, cylinders, and actuators that control machine motion, the FRLs play ...

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