The DMF-Z-40S is a 1-1/2 inch (G1-1/2″) diaphragm pulse valve designed with threaded port connection for reverse pulse-jet cleaning systems. It uses an electromagnetic solenoid to rapidly open and close the diaphragm, releasing a high-pressure compressed air pulse into the blowpipe of a dust collector.

Working Principle of DMF-Z-40S
The operation process is:
- The dust collector controller sends an electrical pulse signal.
- The solenoid coil energizes and opens the pilot valve.
- Air pressure in the upper diaphragm chamber is released.
- The diaphragm opens quickly.
- Compressed air from the air tank is discharged through the valve outlet.
- The air shock wave cleans dust from the filter surface.
- The solenoid closes and the diaphragm returns to its original position.
This cycle usually lasts only a fraction of a second, allowing continuous dust removal without stopping the filtration process.
