we strive to be perfect in every detail.
When there’s no pressure in cup, the floater declines because of gravity, the press cakeclose the inner port and the piston was pressed by spring so that the condensate watercome out from the outfall.
When the pressure is higher than 0.1Mpa, the piston presses upward against the springforce so that the drainage way closes.
When water is condensed to some extent, the floater comes up because of buoyancy sothat the inner port is open and the pressure comes inside, the piston is pressed by springand pressure, then water is drained out.
Note : NPT thread can be customized.
