PENTAIR MECAIR Diaphragm Repair Kits NBR , Viton Dust collector
Ordering Code: DB112
The diaphragm is fit for the Mecair pusle valves: VNP212 , VEM212 ,
VNP312 , VEM312
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 .
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
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
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
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.
