Pressure-compensated flow control valves are designed to provide a constant volume flow rate independent of the pressure drop across the valve. By contrast, non-pressure-compensated valves have a ...

Pressure Control If the distillate is in the liquid phase and the amount of inerts is negligible, the column pressure can be controlled by modulating the cooling water flow through the condenser ...

There are several methods of maintaining head pressure. It is important to understand the principles of how each one operates so they can be set correctly. On systems that utilize more than one method ...

Note that the difference between the boiler feed pump head-flow curve and the system resistance curve (Figure 1) provides the basis for the pressure drop available for the drum level control valve.

The 106-PFC/206-PFC pressure modulation valve is a pressure-reducing valve with a special patented pilot that increases downstream pressure as flow increases. The PFC valve alters and controls ...

But there’s a controversy: Should compressed air pressure/flow control be used, or should modern compressor controls, especially VSD-controlled compressors, be used as an alternative to providing ...

Field proven technology The MFCS™ is a pressure-driven flow controller designed to control independently up to 4 channels of your microfluidic system. This feature means that you can apply the ...

Two case studies present dome-loaded regulator applications in steel mill cooling water and reverse osmosis membrane fouling research.

Have you wondered how your GC system sets and controls gas pressures, flows, and carrier gas velocities electronically? Here, we describe the requirements for and the operation of electronic gas ...

If you’re in the business of oxyfuel cutting, heating, or welding, gas control devices are essential to your operation. Understanding the following about regulators, flowmeters, and adjacent products ...

Have you wondered how your gas chromatography (GC) system sets and controls gas pressures, flows, and carrier gas velocities electronically? Here, we describe requirements for and the operation of ...
