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 ...

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 ...

Tips process engineers can leverage to minimize the time spent selecting actuators for different applications while still maximizing the reliability and durability of valves and automation mechanisms.

Process automation is a necessity in different industries. The utilization of valves implies that process engineers must select the most suitable actuation devices. The actuator should facilitate ...

This file type includes high resolution graphics and schematics when applicable. Today’s manufacturers routinely demand exacting precision and split-second timing from their high-speed production ...

Plant engineers at Eskom’s Majuba Power Station in South Africa have been continuously looking for ways to improve efficiency and reliability. The six-unit, 4,000-MW, supercritical coal-fired plant ...

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 ...

Continuing last month’s fundamentals-based theme, I’d like to address the devices that make closed-loop control work. As discussed, control loop algorithms are implemented by software within a BAS ...

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 ...
