• Reliable use for valves subjected even to the greatest mechanical forces • One single control for up to eight proportional valves • Valves of every make and type can easily be configured online and ...

A proportional solenoid valve is an electromagnetic valve designed to respond to a variable power input to regulate the flow of liquid and/or gas proportionately. It is used to control the flow rate ...

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

Figure la shows the basic operating principle of the mechanical lever. The ratio of the lengths of the lever on each side of the fulcrum determines the multiplication. Principle of the hydraulic lever ...
