Batch manufacturing success depends on accuracy, and that starts with precise, repeatable flow measurement. Even with a fluid ...

What Is the Best VFD Design and Installation Plan? Variable frequency drives (VFDs) are widely used in industrial fan, pump ...

Air can enter water pipelines in several ways, often from dissolved air coming out of solution due to pressure fluctuations, ...

GF Piping Systems developed the Butterfly 565 Lug-Style, which can be used as an end valve, allowing piping systems to be ...

A deep dive into the technological progress of today’s smart valves, bearings, brakes, gearboxes and actuators, and what’s next. Integrating smart technologies, such as wireless sensors and ...

A computer assisting test (CAT) platform of flow characteristics of electronic expansion valves (EEV) is taken as the studying object in this paper, then the mathematical model of experimental system ...

Opposite of tip two above, an over-sized control valve or damper will typically require lower gain and integral PID settings. For example, a drum level control system where the feedwater valve is ...

This paper presents a detailed mathematical model developed for the purpose of predicting the hysteresis characteristics exhibited by miniature high-flow proportional valves. The model is constructed ...
