BFEC Type Right Angle 2-1/2'' Aluminum Alloy Pneumatic Pulse Valve
For Dust Collector DMF-Z-62S
This valve below is DMF-Z-62S right angle type solenoid pulse jet
valve with die-casting aluminum alloy body. It simplifies the
connection between gas bag and blowing tube of a dust collector. It
can provide stronger airflow and meet dust removing requirements.
The high-pressure gas enters from the air inlet , enters the lower
air chamber.
1. When the pulse valve is not energized, the gas enters the
decompression chamber through the impulse valve and the orifice in
the constant pressure pipeline on the upper and lower shells. The
valve core blocks the pressure relief hole under the action of the
spring. The gas will not be discharged, so that the pressure in the
decompression chamber and the lower air chamber are consistent.
Under the action of the spring, the diaphragm will block the
injection port, and the gas will not burst out.
2. When the pulse valve is energized, the valve core is lifted
upward by the electromagnetic force, the pressure relief hole is
opened, and the gas is ejected. Due to the role of the orifice of
the constant pressure pipe, the outflow speed of the pressure
relief hole is greater than that of the decompression chamber. The
inflow speed of the pressure pipe gas makes the pressure in the
decompression chamber lower than the pressure in the lower chamber.
The gas in the lower chamber lifts up the diaphragm, opens the
injection port, and performs gas injection.

FAQ:
1.During installation and commissioning
1). The valve cannot be opened, but the pilot is operating. → Check
if the airbag pressure is too low → Exclude air leaks.
2). Some valves are not working, others are normal.→Check the
valve's wiring link and solenoid coil. → Replacement of
accessories.
3). The valve cannot be closed and there is a leak, pressure cannot
be established. → The inlet of the valve is installed opposite the
injection port. → reassemble
4). The valve cannot be closed and there is a leak. → Impurities
are adsorbed on the diaphragm, and the iron core is stuck. →Clean
the diaphragm, check whether the diaphragm is complete, check the
iron core, and replace the parts in time.
2.During use
1). Valve closes slowly. → Diaphragm orifice blocked. →Dredge
orifice.
2). Some valves leak, the diaphragm does not close,normally opened.
→ Impurities are adsorbed on the diaphragm, the pilot is damaged,
and the iron core is stuck. → Clean the diaphragm, check whether
the diaphragm is complete, check the iron core, and replace the
parts in time.
3). The coil is hot and burned. → Power on for a long time. → Check
the working condition of the control system.
4). There is voltage but the valve is not working. → Damaged
diaphragm or blocked orifice. → Replace parts in time.
5). Low ambient temperature, the valve is leaking or cannot be
opened. → Ambient temperature is too low, there is icing in the
valve. → Note the valve operating temperature range.
