Learning the basics can ease loop tuning frustration and ensure stability. During plant operations, it seems that tuning control loops is an ongoing task, which can be a continual frustration to ...

Flow is controlled by either throttling or diverting it. Flow is controlled by either throttling or diverting it. Throttling involves reducing orifice size until all of the flow cannot pass through ...

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 ...

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, ...

Directional valves such as Parker Hannifin's B3G-Series threeway (left) and four-way valves are often used to control pneumatic operations. Directional-control valves are vital in any pneumatic ...

Abstract: In this study, we have fabricated and evaluated a flow control valve for oil-hydraulic soft actuators. To install oil-hydraulic actuators on a robot to realize actuation with high-power, ...

Please note: This year, I want to help us laugh and learn by making one of my humorous books available to download for free over each of the next six columns. The ...

Pneumatic control systems are used in various applications, including: A single acting cylinder (SAC) is a type of pneumatic actuator that produces force and movement in one direction only. It has a ...
