AC110V DC12V 3/4'' Inch DN20 DMF-ZM-20 Right Angle Aluminum Alloy Body Control Solenoid Valve
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.
Working Principles
The electromagnetic pulse valve is composed of electromagnetic pilot operator, diaphragm and valve body. Due to difference of pressure acting on two sides of the diaphragm, the diaphragm is pressed closely against the outlet of valve to keep the valve stays in “closed” position.
1)When energized by an electric signal from the controller, the electromagnetic armature will move to open the discharge opening of back cavity. The compressed air in back cavity bursts out to relief pressure and pressurized air in front cavity pushes up the diaphragm to open the main outlet of valve, then the electromagnetic pulse valve opens and starts to blow.
2)When the signal disappears and the spring works immediately to send the pilot operator back to its original position and close the discharging opening. The diaphragm will close the passage by the effect of the pressure in the front cavity and the spring. The pulse valve stops blowing.
3)The orifice in the diaphragm damps the airflow when the armature is lifting up for releasing the pressure. When the discharge hole closed, the pressure gas will fill into the front cavity to close the passage by the diaphragm. The pulse valve stops blowing.

Features Of DMF-ZM Series Pulse Jet Valve
1.We Can provide three specifications of valves from 20, 25, and 40S for the selection of pulse bag dust collectors.
2.The valve body and valve cover are densely die-cast, anti-corrosion performance.
3.The gasket on the diaphragm is made of metal and rubber, which has good rigidity and does not leak.
4.The electromagnetic pilot head has a large suction force and is sensitive and reliable.
5.The performance is stable and reliable, and the service life of the diaphragm reaches more than one million times or three years.
Note
A. The inlet and outlet ends of the nozzle and the injection pipe inserted into the electromagnetic pulse valve should be maintained at a certain depth. 20 valves is not less than 15 mm.
B. The ZM valve body cannot be used to support and fix the air distribution box (air bag) and the blowing pipe. Special measures shall be taken to support and fix it.
