Medium Pressure 2 1/2 Inch Pneumatic Pulse Valve Aluminum With NBR Diaphragm
DMF-Y series electromagnetic pulse valve is also called submerged pulse valve. It is suitable for medium or low air supply pressure. It adopts NBR diaphragm, which is more durable, and has a common general diameter and a wider spray area.There are a variety of voltages to choose.
If you need pulse valves of other caliber or other kinds, we can provide as long as you contact us.
Feature of DMF-Y-62S
1.Hot forging process, small size, fine appearance
2.The piston structure is novel and the service life is longer
3.Better fluency
4.Low resistance, good fluency, high injection volume

Performance test
1, open voltage test
In the air inlet of the electromagnetic pulse valve, connect the clean air with the nominal pressure of the air source. Input the electric signal of 85% of the nominal voltage and 0.03s of the width on the electromagnetic valve to check whether the electromagnetic pulse valve is open normally.
2, close the air pressure test
In the air inlet of the electromagnetic pulse valve, connect the clean air with a pressure of 0.1 MPa, input the electrical signal to close the valve, and check whether the electromagnetic pulse valve is reliably closed.
3, pressure resistance test
In the air inlet of the electromagnetic pulse valve, the clean air with a pressure of 0.8 MPa is connected for 60 minutes, and the leakage of the sealing parts on the electromagnetic pulse valve is checked.
4, insulation resistance test
(1) Measure the insulation resistance of the electromagnetic coil to the outer casing under the specified environmental conditions with a 500V meter range of 0MΩ~500MΩ and a precision class 1.
(2) Put the valve in the temperature regulation and humidity control box, and set the temperature to 35 degrees, and the relative humidity is 85%, apply a 50Hz, 250V sinusoidal AC voltage between the electromagnetic coil and the valve body for 1min. Check for breakdown.
5, anti-vibration test
The valve is fixed on the vibration test bench, and after the vibration frequency is 20 Hz, the full amplitude is 2 mm, and the vibration is 30 min, the fasteners of each part of the valve are checked for looseness and the work is normal.
6, diaphragm life test
The clean air of the nominal pressure is connected to the air inlet of the electromagnetic pulse valve, and the nominal voltage value of the width of 0.1 s and the interval of 3 s is input on the electromagnetic valve, and the number of consecutive or cumulative operations of the valve is recorded.
