BFEC DMF-ZM-20 Dresser Nut Type 3/4'' Inch Diaphragm Dust Collector Valve
The DMF-Z solenoid/diaphragm valve is kind of vertical-angle valve, with an
included angle of 90° between inlet and outlet. 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 DMF-Y solenoid/diaphragm valve is kind of submerged valve (namely,
insert valve), which is installed directly on a secondary gas bag
and achieves better circulation quality. The valve has less
pressure loss, and is applicable to the operations with lower gas
pressure.
DMF-ZM The Solenoid/Diaphragm valve pulse jet valve is kind of
vertical-angle valve similar to the z-series valves, suitable for
connection between gas bag and blowing tube of a dust collector. It
has fixed nuts for installation purposes at the inlet and outlet
end, for easier installation and application.
The DMF-T solenoid/diaphragm valve is kind of through valve, with an
included angle of 180° between the inlet and outlet (central line
of both inlet and outlet are the same straight line). Also, the
inlet is connected to a gas storage tank, while its outlet is
connected to a blowing tube.

The factors that affect the diameter of the dust bag filter bag of
an industrial dust collector are:
1. The size of the bag diameter is related to the pulse energy of
the cleaning pulse and the arrangement of the pulse valve. The
diameter of the common pulse industrial dust collector is generally
between 120mm and 152mm.
2. The bag diameter is related to the size of the dust collector.
For example, on the ground of about 7.5m2, a filter bag with a
diameter of 152mm and a length of 3m is used, and the filter area
is about 163m2. If a filter bag with a diameter of 305mm is used,
it will take 4.3m to get the same on the same area of the ground.
Filter area.
3. The bag diameter is related to the width of the filter material.
Various filter materials have their own scale widths. In order to
maximize the utilization, the bag diameter will be determined by
the width of the filter material. For example, a fabric with a
width of about 990mm can be made into two filter bags with a
diameter of 152mm, leaving the necessary seams to overlap.
