Control valves are power-operated devices used to automatically modify fluid flow or rate pressure in a process system. The terms 'control valve' and 'throttling valve' are often used interchangeably ...

"Pneumatic Control Valves" provides an overview of different common pneumatic valves, including regulating, directional control, relief, flow control, and sequence valves. A pneumatic system uses ...

Pinch valves, the simplest valve design, include any valve with a flexible elastomer body that can be pinched close to cut off flow, using a mechanism or fluid pressure. They are linear motion valves ...

Piezo elements are electromechanical transducers that convert mechanical forces (pressure, tensile stress or acceleration) into voltages. The inverse piezoelectric effect, precisely the opposite, ...
