4.2 Filtration
During normal operation, the medium coming from the system enters in the strainer body through the motorised ball valve V1. The medium is forced
to pass through the filtration discs, then it is conveyed into the central part until it comes out of the device through the clapet check valve.
4.3 Filtering elements cleaning
It can be activated manually, by time or automatically by controlling the medium pressure drop between internal pressure and pressure detected after
the filtering elements. The choice of the type of operation is carried out by the regulator. During the first cleaning phase (emptying) the inlet ball valve V1
closes while the clapet check valve prevents the system backflow. Once the inlet valve V1 is completely closed, the drain valve V3 is opened, located
in the lower part of the device. When the vacuum breaker valve, present in the upper part of the strainer body, is opened it allows the progressive
draining of the tank, causing part of the dirt to come out.
