Valves and actuators device review

Although the basic technology for most valves and actuators has remained unchanged, innovative applications and design modifications for problem solving have led to notable improvements in actuator technology. These improvements can reduce costs by supporting the control valve's ability to throttle accurately, thereby providing better performance for high-pressure steam bypass, turbine bypass and other critical power plant operations. Actuators regulate mass and energy flows by adjusting valves, flaps and cocks.

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 single board computer. They are used in a wide range of applications, including pollution control, feed water, cooling water, chemical treatment, bottom ash and steam turbine control embedded systems.
