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.

ORIENT PCL        Cleaning the air for the better Returns Regular Hopper Entry: The pulse jet bag filter in its most rudimentary form basically consists of the filtration elements housed in a casing. Below this casing is a hopper with a discharge valve, to continuously remove the dust that is collected on the bags. The entire unit is supported from the ground on structural legs. A caged ladder provides access to the top of the unit for maintenance. The dust laden air enters through the hopper by suction (normally) or (positive pressure). The heavier dust particles fall off at the entry itself, while the lighter dusts get carried upward to the bags.                                                  ...
