SOLENOID-VALVE CONTROL SYSTEM

DRIVE May 10, 2017
Source
Described herein is a system for controlling a solenoid valve, which comprises a driving circuit (10) for driving the solenoid of the solenoid valve and a control unit (20) for controlling the driving circuit. The control unit is configured for generating in the solenoid, during operation of the solenoid valve: - a first current signal (T) for moving the open/close element from a first position to a second position, which is generated by the external supply network, to which the solenoid is connected; and - a second current signal (T'), which is generated exclusively as a result of the residual magnetism in the magnetic element of the solenoid valve and is activated when the open/close element is still in the aforesaid second position.
