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 ...

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 ...

Valves and actuators are critical in almost every aspect of power plant operations. They are used in a wide range of applications, including pollution control, feed water, cooling water, chemical ...

If you suddenly have the need for a two-way, flow control valve — from a valve-selection standpoint — what kind of questions do you ask yourself? Many, perhaps, don’t ask any questions and may make ...

The new generation of 435 Series actuators will replace the prior AME 15QM Series of actuator for the AB-QM pressure-independent control valve (PICV). The AME 435QM and AMV 435 are the first of a new ...

This standard provides basic requirements for pneumatic valve actuators of the double-acting and single-acting types, used for on-off and modulating valve duties. It includes guidelines, ...

Rotork recently installed and commissioned CVL linear control valve actuators at Didcot B Power Station, which supplies electricity to the National Grid. Rotork’s CVL1500 and CVL5000 actuators now ...

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 ...
