SCG353A051 2 1/2'' ASCO Replacement Pulse Valve DC24V
The 353 Series in aluminum is a range of diaphragm valves suitable
for dust collector applications, in particular for reverse
pulse-jet filter cleaning of filter bags, cartridges, envelope
filters, ceramic filters and sintered metal fibre filters.
Diaphragm pulse valves are for controlling air pulses in dust
collectors. Valves are offered in both integrated and remote coil
configurations. These valves are part of the mechanism that
operates the reverse pulse of air that cleans the filters.

Working principle of 353 series dust collector valves:
The two chambers of the dust collector valves are connected
together through an air passage (smaller in diameter than the pilot
valve orifice when so equipped). When the orifice is opened, the
air in the upper chamber is exhausted, at a much faster rate than
the speed of which air enters through the air passage, therfore the
air pressure in the upper chamber drops significantly. As this
occurs, the higher air pressure in the lower chamber pushes the
diaphragm up allowing a large volume of air through to the bottom
chamber and its outlet connected to the dust collector bags. This
sudden burst of air inflates the filter bags or "pops" the filter
bags so as to shake loose accumulated material on the outside of
each filter bag. When the orifice closes, the pressure in the upper
and lower chambers equalize and the diaphragm returns to its
original position, aided by the force of a return spring. The dust
collector valves are important components to keep dust collector
systems operating efficiently and effectively.
