4-inch submerged pulse valve, the valve seat is embedded in the air bag for installation, with small resistance, good fluidity, high injection volume, increased load with momentum, expanded the range of use of gas source pressure, suitable for use in occasions with wide gas source pressure. Technical requirements for 4-inch submerged pulse valve: 1. The working pressure of the product is 0.1mpa-0.7mpa, and the medium is the air treated by oil and water removal. 2. When the working voltage of the Solenoid Valve is 85% of the rated voltage under the nominal supply pressure of the product, the opening response time of the solenoid pulse valve shall be less than 0.03s. 3. When the working air source pressure is 0.1MPa, the pulse valve can be closed. 4. The product shall be able to withstand the air source pressure of 0.8MPa. 5. Under the specified environmental conditions, the insulation resistance of the electromagnetic coil to the shell shall be greater than 1m Ω. 6. When the room temperature is 5-35 degrees and the relative humidity is not more than 85%, the electromagnetic coil can withstand 50Hz and 250V voltage to the shell, and there is no breakdown phenomenon for 1min. 7. The electromagnetic pulse valve shall be able to work normally after bearing the vibration with frequency of 20Hz, full amplitude of 2mm and duration of 30min. 8. Under normal service conditions, the cumulative service life of the diaphragm shall be more than 800000 times. 9. There is no obvious coating peeling, scratch, burr and other damage on the surface of the valve.
