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 ...

Lee Company’s new High Pressure 500 Pilot Operated Chek is the latest addition to Lee’s line of miniature check valves. This valve acts like a normal check valve until pressure is applied to the pilot ...

The Anderson Greenwood Series 5100 pilot-operated pressure-relief valve is designed for over-pressure protection of economizers in fossil-fired power plants. The Anderson Greenwood Series 5100 ...

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, ...

Compressible fluid flow through control valves will inevitably cause some form of flow-induced vibration in the fluid system. Identifying the type and cause of the vibration requires detective work.

[Editor's note: This is the second installment of a two-part series on head pressure control.] In part 1 of this article, on the fundamentals of head pressure control ("Fundamentals of Head Pressure ...

Microfluidic technology has developed greatly in recent years, enabling multiple analysis systems to be placed on a microfluidic chip. However, microfluidic large-scale integration of control elements ...
