1. Precision Control for Liquid Extraction Applications

   ... valves per line—fluid isolation valves, vacuum valves, and air piloted valves. ............................................. ...

2. Isolation Valves - An Overview of Different Types

   ... Pinch valves may be operated by electricity, air pressure, or manual operation. The operation power of electrically-actuated ... tubing. Another advantage is size—since pneumatically piloted units are able to provide more force, the size can be scaled down to ...

3. Digital vs. Analog Control in Proportional Applications

   ... high-resolution control without a bleed orifice. Compressed air is costly enough to produce, but introduce oxygen or helium into a process, ... higher flow than the maximum orifice size available. Air piloted mechanical regulators increase flow potential for electronic ...
