ACCU-PULSE DMF-Z-20 pulse valve

DMF-Z-20 pulse valve is a right-angle electromagnetic pulse valve commonly used in pulse-jet bag dust collectors as a “switch” for compressed air. The detailed introduction is as follows:

Working Principle

The diaphragm divides the electromagnetic pulse valve into front and rear air chambers. When compressed air is connected, it enters the rear air chamber through the orifice, and the pressure in the rear air chamber presses the diaphragm assembly tightly against the valve’s outlet, keeping the electromagnetic pulse valve in the “closed” state. When the pulse injection control instrument sends an electrical signal, the armature of the electromagnetic pulse valve moves backward, opening the rear air chamber and rapidly releasing pressure. The diaphragm assembly moves backward, allowing compressed air to spray out through the valve outlet, and the pulse valve enters the “open” state. When the electrical signal from the pulse injection control instrument disappears, the armature of the electromagnetic pulse valve resets, the exhaust port of the rear air chamber closes, the pressure in the rear air chamber rises, and the diaphragm assembly moves close to the valve’s outlet, re-closing the pulse valve.

Technical Parameters

Connection Thread: G3/4″
Working Pressure: 0.2–0.7 MPa
Applicable Medium: Clean air

It is mainly used in the dust-cleaning injection system of bag-type dust collectors. By cooperating with a pulse injection control instrument, it performs row-by-row (chamber-by-chamber) injection cleaning on filter bags, maintaining the dust collector’s resistance within a set range to ensure dust removal capacity and efficiency.
