Solenoid valves with flow limiter

This is a control system that allows the passage of the liquid for filling from a main reservoir to a daily tank through an Oil Pressure Unit (system which lifts the oil) and a level switch (system which open/close the solenoid valve at low / high level). When liquid drops at the daily tank till the low level point, th level switch sends a signal to keep open the solenoid valve until the switch sends high-level close signal. In addition, the flow limiter, which is adjusted to allow passage of a constant flow, but keeping the pressure at the pipe generated by the Pressure Unit, avoiding the safety low pressure blockage. The filter is responsible for preventing dirtiness to be placed in the membrane of the solenoid and protecting the installation.
