Mecair DB120 Diaphragm Repair Kits NBR , Viton , Nitrile Integral Or Remote Pulse Jet Valves

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.

Ordering Code: DB120

The diaphragm is fit for the Mecair pusle valves: VNP220 , VEM220 , VNP320 , VEM320, VNP420, VEM420, VNP620, VEM620, VNP620, VEM720


Metial: Nitrile or Common rubber

Use:For the Pulse Jet Valves

Structure and Performance:
Coating both sides of a single layer or multiple layers , and the fabric does not clip with rubber . Method according to their shape of the membrane pressure method . According to different requirements can be manufactured of plastic material, different fabric diaphragm. Performance of nitrile rubber diaphragm with a blend of rubber and polysulfide rubber material , sandwiched canvas disc diaphragm ( often called the diaphragm ) used some of the silicone rubber, fluoro rubber, epichlorohydrin rubber material properties and the recent development see description below the diaphragm performance .
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.
Diaphragm itself operating temperature range and pressure range depends on the types of plastic , fabric and structure. The diaphragm can be operated at -50 to 100 ° C , 0.4 ~ 0.8MPa conditions ; fluorine rubber and silicone rubber diaphragm 232 can work in -80 degrees Celsius . Epichlorohydrin rubber diaphragm can work under pressure 0.4 ~ 0.8MPa , air tightness, anti-aging , longevity and engine overhaul life equal.

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.
