Dust Collector Pulse-Jet Valve Operating Sequence:
1. Differential pressure (DP) builds across the filter bags/cartridges as dust
load increases in the collector.
2. Once DP reaches a pre-set point, the pulse-jet cleaning system is
activated to go through a cleaning sequence/cycle, as programmed in the
timer board or other controller.
3. The timer board (or other controller) then sends an electrical signal to
the pilot solenoid valve(s), causing the coil to energize, thus pulling the
valve plunger into the open position allowing the compressed air in the
pneumatic line to bleed to atmosphere. (NOTE: The pilot solenoid valve
can be direct-mounted (mounted directly on top of the diaphragm valve,
or it can be remote-mounted (mounted in a solenoid enclosure separate
from the diaphragm and connected with pneumatic tubing, as shown
4. Bleeding the compressed air line to atmosphere causes an imbalance in
air pressure within the diaphragm valve. In other words, the air pressure
suddenly drops on the top-side of the diaphragm valve as the pneumatic
line is bled to atmosphere.
5. The change in pressure difference within the diaphragm valve causes
the compressed air manifold (compressed air tank) to force the diaphragm
up from its seat, thus allowing compressed air to bypass the diaphragm
and be expelled into the blow-tube. The “pulse” of compressed air then
blows the dust off of the filter bags/cartridges.
