Refrigeration control valves for industrial refrigeration systems have been an important system component since the 1920s. When a control valve fails, the result can be as significant as a more costly ...

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 ...

Feedwater control valves play a critical role in boiler operation. One important parameter of their design is the pressure drop at the rated condition as well as off-design conditions. However, ...

Maintaining valves throughout a plant’s lifetime helps to preserve optimal performance, minimize supply disruptions and ...

Understanding which valve to use in which application is essential to operate a steam power plant as efficiently and cost-effectively as possible. For example, a critical step in steam power ...

A worksheet that calculates control valve installed gain can be part of any control valve selection process. For many years, the author has used, and promoted the use of, control valve installed flow ...

studying control valve user requirements for dynamic performance of control valves defining of terms, performance categories, test methods and instrumentation, performance parameters, specification ...

Cleaning the idle air control valve (IACV) on your vehicle periodically helps keep carbon and other particles from building up on the valve, which can negatively affect the operation of the car.

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