This model DMF-Z-25 straight-through pulse jet valve (Accu-Pulse brand) is a key pneumatic control component for industrial dust removal systems, equipped with an explosion-proof electromagnetic coil.
Main Functions
It serves as an air injection switch for dust collectors. Receiving electrical pulse signals from the controller, it instantly opens and closes to release compressed air.
It generates high-pressure airflow shockwaves to blow off dust accumulated on filter bags / filter cartridges inside dust removal equipment.
The matched explosion-proof solenoid coil enables safe operation in flammable and explosive working environments.
Working Principle
When the solenoid coil gets a pulse signal, the internal pilot structure is activated. The pressure balance inside the valve breaks, the valve diaphragm opens rapidly, and compressed air surges into the filter chamber for dust cleaning. Once the signal disappears, the valve automatically closes to finish one ash-blowing cycle.
Main Purposes
Widely installed on pulse bag dust collectors, cartridge dust collectors and other industrial dust removal equipment.
Periodically cleans filter elements to prevent filter media blockage, maintain stable air permeability and continuous dust collection efficiency.
Explosion-proof design satisfies application requirements in industries including chemical processing, grain processing, metallurgy, coal dust treatment and other hazardous locations with combustible dust.
