The pulse valve diaphragm is a high-quality rubber diaphragm which
is provided with a rivet head for sealing the air outlet of the
compressed air duct or the plugging valve, a venting relief hole
and a bolt hole for fixing the support. It is the key control
component in the electromagnetic pulse valve.

Pulse jet valve
1. Used outside of bag-type duster sack-duster’s blowing and
cleaning ash.
2. Adopte this kind of structure that submerge in the air porket..
3. Compare to other structure, reduce resistance in interval
channel and pressure of blowing supplier.
4. So it adapt siuation of low pressure, reduce energy consumption
and prolong membrance patch using.
Produce Structure
Tract: Valve’s crust and close over is made of aluminum alloy
that’s formed by pressing die, good appearance, heavy intensity, no
gas leak. Structure of connection of two back pressing air of
interval channel of valve is reasonable. this design make
“ubmerged-type” true due to opening and closing face of valve
locate in air pocket. Air from pocket can come in blowing
cannulation straightly. It accord request with low air pressure and
big quantity of blowing.
Electromagnetically operated valve: Control pulse valve by
remoting. With trube base coil and DIN electrical outlet, conwiniet
inner setting or outer setting, waterproof and dustproof for
protect. Upto JB/t5916-91 standard.
Membrane patch: Adopt dish-type, and big moving. Valve can be
opened in 0.08-0.1 second. You can choice synthetic rubber membrane
patch made of import materials in frigid climate. Membrane patch
can be longest used when working temperature is from -40℃ to -55℃.
1, Technical Paremeter
1Acclimation:
1) Temperature: -10~+55℃;
2) Working Medium: clean air
2Humidity: less than 85%
3Blowing Supplier Pressure: it’s better 0.2~0.3Mpa,or0.3~0.6Mpa.
4Blowing Tolerance: when blowing supplier pressure is 0.25Mpa and
blowing time is 0.1 second.

The installment introduction:
1. First, Confirm the pulse valve in good condition and then
installed
2. Pulse valve will be installed directly the outer wall of flange
of gas manifold. The spray pipe across the gas manifold. According
to the drawing and manual, the pulse valve matching appropriate
spray pipe and installation. To avoid the valve install in the air
manifold bottom. If the pulse valve matched trachea and connector,
the connector will be used for sealing purpose only. It can not as
structural support components. It can not rely on the straight
connector fixed spray torch and package. The spray pipe and air
manifold must be fixed independent.
3. To tighten the hard nut, the maximum torque of 20 N*m.Tighten
the trachea, torsion of 20 N*m.
4. The connection control wire needs connect of every electric
control valve seat. Pay attention to the line adown to prevent rain
waterproof. Or through the joint and nylon pipe, it will connect
the pulse valve and electromagnetic assembly boxes of nylon pipe
connection.
5. To ensure that provide compressed air clean and dry. The air
manifold system provides moderate pressure and check for leaks
installation. ( it can brush on soap and water, check whether the
interface is bubble). Pressure was carried out on the air bag
inflated (pressure of the valve is around 0.03 ~ 0. 86 mpa),
recommend for air pressure 0.8 mpa maximum
6. Testing the pulse valve blowing, listening all the pilot valve
whether it is normal operation and whether the pulse blowing sound
is clear.
After-sale Service
We can provide a series of after-sale service, such as product
introduction, mounting, debugging, technical support and so on.
The exhaust chamber volume of improved DMF pulse valve is
increased. The permeability magnetic material of pulse valve is
increased, and also, the materials of structure of diaphragm and
pressure spring are improved, so that the exhaust volume of valve
is increased to raise the magnetic strength and sensitivity as well
as the element reliability and operation stability of pulse valve.
Its service life will be greatly prolonged.
