Membrane valve has channel in wall between upper air chamber and lower air inlet opening, and upper membrane seals full-faced so that with opening and closing of solenoid valve upper and lower membranes can react simultaneously
Membrane valve has channel in wall between upper air chamber and lower air inlet opening, and upper membrane seals full-faced so that with opening and closing of solenoid valve upper and lower membranes can react simultaneously
The membrane valve comprises at least two air chambers (21,22) each with a connector (31,32) and air inlet opening (41,42), with a membrane (51,52) in between. A channel (6) is provided in the wall between the upper air chamber and lower air inlet opening, and the upper membrane (51) seals full-faced, so that with opening and closing of a solenoid valve on the upper air chamber the upper and lower membranes can react simultaneously without the delays which characterize current designs.
