After switching a solenoid valve by applying the specified voltage, the valve can also maintain this position at a much lower voltage (holding voltage). For example, if a valve is switched with 24 VDC, the voltage can be reduced to 10 VDC under normal conditions to maintain this position.
This circuit provides various advantages, such as a significantly lower power consumption and significantly lower heating of the solenoid, optimisation of the reaction time, increased working pressure, minimisation of sizes, etc.
Valves with integrated electronics for holding voltage
The diaphragm-separated solenoid valves, the pinch valves and the special solutions of the Analytical- & medical technology are available with integrated electronics for holding voltage. The electronic is optionally available for the individual valve series. It is integrated in the valve cable and will be delivered together with the valve.
