They work in harsh environments, and they get little or no recognition. But their impact on power plant efficiency can be significant. Valves and actuators are critical in almost every aspect of power ...

When an electric utility with a power plant in the southwestern U.S. prepared for a planned, major outage on its two Siemens 501D turbines, the plant’s manager requested a repair quote for two ...

At a time of surging demand for electric energy, the power industry has to ensure reliable and stable supply with the flexibility needed to handle intermittent wind and solar generation. Through ...

Electric rod-actuators are replacing fluid power actuators for many high-force applications throughout industry. Tasks once limited to hydraulic and pneumatic cylinders such as pressing, holding, ...

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

However, not all innovations are equal, and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

Linear actuators are a great help when you’re moving something along a single axis, but with so many options, how do you decide? [Jeremy Fielding] walks us through some of the high level tradeoffs of ...

Actuators with built-in encoders and precision guidance enable position, speed and force adjustments on-the-fly without mechanical reconfiguration or production delays. Integrated diagnostics monitor ...
