The automatic drain can be connected by its inlet wherever condensate needs to be drained (compressor, filter, dryer). The internal tank collects the liquid and the diaphragm keeps the drain hole closed thanks to the pressure exerted on its surface. When the liquid level increases, the float moves up and when it reaches the maximum level, it activates the solenoid valve due to the magnetic contact, that leads to the opening of the pilot valve. A lack of pressure on the diaphragm allows the liquid to be drained. When the liquid reaches the minimum level, the pilot valve moves down, and draining holes are closed again without losing air pressure. An integrated filter is used to hold the impurities contained in water condensation to guarantee the correct operation of the valve even in the most critical applications. By pressing the test button it’s possible to open the drain valve manually and check the correct functioning of the drain.
