Solenoid Valve

Solenoid Valve

The pulse of compressed air is controlled by series of pulse solenoid valves that are placed on air reservoir. These in turn are connected to compartment manifold pipe, which open above the venturi of each bag in that row. The diaphragm of the pulse valve is closed as the compressed air is trapped between diaphragm and solenoid valve orifice. When the solenoid valve is energized through an input signal from the sequential controller, the trapped air flows from the top of the diaphragm through the orifice of the solenoid valve.

The inflowing compressed air lifts up the diaphragm and flows through the outlet of the pulse valve. Again, when the solenoid valve is de-energized, the air gets trapped, closing the diaphragm as a result of pressure equalization. The next solenoid valve gets energized and the entire process is repeated sequentially in cycle.
