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 ...

Proper valve sizing and selection saves facilities money by improving plant uptime and decreasing maintenance costs. One way to improve the selection of valves for a particular application is to take ...

The complete Nelprof™ valve sizing and selection software for all intelligent automated process valves by Neles is now available as a free web-based tool. With its advanced control-valve selection ...

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 ...

Bio-Chem Valve™ Flow Selection Valves reduce the number of connections and potential leak points in flow mixing and selection for highly aggressive and high purity fluid applications. Flow Selection ...

3D printing techniques enable quieter, higher performing designs for final control elements. Control valve noise is a problem in many plant environments. The sound is created by very high pressure ...

Directional-control valves are vital in any pneumatic circuit, directing or blocking airflow to control the speed or sequence of operations. One method of classifying directional-control valves is by ...

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, ...

In current designs, the electronics controlling the valve are separate from the valve itself. The correct term to describe the valves is therefore electronically controlled electric valves. Since ...
