DMF-Z-2-20 pulse valve with nut 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:
DMF-Z-2-20 ACCU-PULSE 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.
DMF-Z-2-20 ACCU-PULSE Technical Parameters
- Connection Thread: G3/4″
- Working Pressure: 0.2–0.7 MPa
- Applicable Medium: Clean air
- Working Voltage: DC12V, DC24V, AC110V, AC220V, etc.
- Diaphragm Service Life: Over 1 million injections
Product Features
- Large Air Chamber Volume: The diaphragm lifts to a large height, delivering a high injection volume and providing sufficient dust-cleaning power for the dust collector.
- Flexible Installation: It allows for a larger installation distance, making it easy to operate with tools during installation and offering suitable installation methods. Meanwhile, the larger spacing between filter bags prevents bottom collisions and friction of long bags.
- Superior Diaphragm Performance: The diaphragm is thin, tough, and highly elastic, enabling a large injection distance for each pulse. Even 8-meter-long dust bags can be injected to the bottom.
DMF-Z-2-20 ACCU-PULSE Application Field
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.
