Figure 1. High-pressure district or campus steam is reduced to lower pressure for building use. The controller receives the low-pressure steam reading from the transmitter and regulates low-flow ...

Equipment designers find that proportional control technology is ideal where precise performance is required in variable pressure or flow applications. Often perceived as more complicated than other ...

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 ...

On/off valves are basically on/off switches for hydraulic systems. They are typically installed in applications where precise position or speed control is not required. Proportional valves adjust flow ...

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 ...

Due to historical engineering decisions made many decades ago, a great many irrigation systems rely on solenoid valves that ...

Among the various types of valves on the market, ball valves are critical in high-pressure systems, enabling precise fluid control in industries like power generation, chemical processing, and oil and ...
