Operation
Figure 1: Condensate drain, standby mode and discharge mode
The drain is connected to the point where the elimination of the condensate is required (tank, filter,
dryer, etc.), by means of the connection supplied (1).
The accumulation tank (2) collects the condensation and the diaphragm (3) keeps the drainage
hole closed thanks to the pressure exerted on its surface.
As the liquid level rises the float (4) rises and, as soon as it has reached the maximum filling level,
the solenoid (5) is triggered by means of the logic control circuit, to open the pilot valve (6).
As compensation is lacking, the diaphragm is lifted allowing the discharge of water to bring the level
in the tank back to a minimum (3), to then close the passage of the discharge without letting air
escape.
The product is also equipped with two components that are very useful for ensuring functionality
and reliability.
An integrated filter cup (7) and a flow regulator (8) inserted into the hose holder (9). The first is used
to retain the impurities contained in the condensate, to ensure a perfect operation of the valve even
in the most critical applications. The second, instead, is used to control the discharge flow, slowing
the purging to avoid an additional oil emulsion that, in most cases, is present in the condensate
water.
By pressing the test button it is also possible to manually actuate the discharge in order to control
the functionality; it can be also useful for unblocking in the event of faulty operation.
