The valves are constructed in die-cast aluminium and have an anodised pretection treatment which protect them from corrosive and environmental agents, Bolts and screws are in stainless steel. The 200 series is available in the following versions:
VNP, with integrated pilot
VEM, with remote pneumatic connection

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.

Drawings size:

High purity Aluminum Alloy casting body, the top of NBR diaphragm, make the diaphragm has high tensile strength, ageing resistance and low wear, the electromagnetic pulse valve injection is longer than that of 1 million or three to five years with no damage.
All high-quality imported finished diaphragm, diaphragm assembly in the manufacturing process all checks, qualified and then into the assembly line. Each finished valve is tested by ventilation.

Electromagnetic pulse valve coil is higher than the national standard grade insulation injection in the protection class is IP65 full filling, full copper enameled wire, coil number higher than the national standard, ensure the electromagnetic pulse valve 6 million is energized is not damaged, the electromagnetic coil can rotate 360 DEG in the pulse valve, the junction box can rotate 90 degrees to 4 x can be installed to prevent exposure in the open when rain enters, greatly facilitate the installation of different angles.

Introduction

Electromagnetic pulse valve refers to the gas through the valve in instantaneous once a electrical signal received. Just like pulse phenomena, it has the change of the short fluctuation. Therefore it is calls the pulse valve. The Industry standard definition of electromagnetic pulse valve for electromagnetic pilot valve and pulse valve together, diaphragm valve controlled by electrical signals.

Working principle

Electrical pulse controller send input signals so that the electromagnetic armature attracts the moving bar. Unclose the balancing hole to release the pressure gas in the back cavity of diaphragm quickly; the pressure gas in the front cavity holds up the diaphragm to open the passage and the valve starts cleaning.

The pulse signal disappears and the spring of the armature works immediately to resume the moving bar so as to close the balancing hole. The pressure gas in the back cavity of the diaphragm and the spring work together to close the passage the valve stops cleaning.
The damping hole in the diaphragm functions to damp the airflow when the moving bar of armature holds up for balancing and to transit the air to the back cavity as soon as the balancing hole is shut to close the passage and stop cleaning.

Delivery
1. If the products we have in store, we will send it out ASAP after payment.
2. If the products which were customized, we will complete the production within a specified period of time, and send it out the first time, we can promise it.
3. Also we can send by your delivery acount if you want.
4. We have a variety of ways to send goods, usually DHL, Fedex, TNL will be normal ways. If you require use of a courier, we can do it.

Competitive Advantage

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.
