Fluid-Control Systems: Business Overview

A fluid-control system is the technology for managing and regulating the flow of liquids and gases. Its primary purpose is to govern flow rate, direction and pressure so that the fluid reaches its intended point in the required manner. This technology is integral to everyday life—turn on a faucet and a miniature fluid-control system instantly adjusts water speed and volume.

1. Hydraulic Control  

   Hydraulic systems use oil as the working medium.  

   • High power density—large force in a compact package  

   • Fast response—rapid start, stop and reversal  

   • Infinitely variable speed and inherent lubrication  

   Drawbacks: risk of leakage, oil contamination and flammability.

2. Pneumatic Control  

   Pneumatic systems use compressed air.  

   • Rapid actuation—ideal for high-speed cycles  

   • Low cost—components and medium are inexpensive, making retrofits attractive  

   Limitations: less smooth motion, higher noise level, larger control-element footprint.

3. Applications  

   Fluid control is embedded throughout industry—hydraulic presses, pneumatic tools, automated assembly lines and more. Properly engineered systems raise equipment automation and overall productivity.
