The ACCU-PULSE DMF-Z-25 pulse valve Working Principle
The DMF-Z-25 pulse valve is a pilot-type solenoid valve. When energized, the electromagnetic force drives the pilot valve to open, rapidly reducing the pressure in the upper cavity of the main valve. A pressure difference is formed between the upper and lower cavities of the main valve, and the medium pressure pushes the closing member of the main valve upward, opening the valve and allowing compressed air to spray out through the valve outlet. When power is cut off, the spring force closes the pilot valve, and the inlet medium pressure quickly enters the upper cavity of the main valve through the pilot hole, forming a pressure difference in the upper cavity to close the main valve and stop the pulse valve from exhausting air.The ACCU-PULSE DMF-Z-25 pulse valve Technical Parameters

Electromagnetic Pulse Valves: Opening a New Era of Intelligent Industrial Cleaning
With the advent of the intelligent industrial era, electromagnetic pulse valves are also actively integrating into the intelligent wave and becoming a key part of realizing intelligent industrial cleaning.
Intelligent electromagnetic pulse valves are equipped with advanced sensors and intelligent control systems. These sensors can real – time monitor key parameters such as the resistance of the filter bag, dust concentration, and the operating status of the equipment. Take the large – scale dust removal system in a chemical enterprise as an example. The sensors transmit the collected data to the intelligent control system in real – time. The system analyzes and processes these data to accurately judge the ash – cleaning requirements of the filter bag. When the resistance of the filter bag reaches the set threshold, the intelligent control system automatically issues an instruction to control the electromagnetic pulse valve for ash – cleaning operation. Moreover, the system can automatically adjust the injection time, injection interval, and injection pressure of the electromagnetic pulse valve according to the actual situation to ensure the ash – cleaning effect while minimizing energy consumption.The intelligence of electromagnetic pulse valves is also reflected in remote monitoring and fault diagnosis functions. With the help of the Internet of Things technology, enterprise managers can remotely monitor the operating status of electromagnetic pulse valves at any time through terminal devices such as mobile phones and computers. Once a fault occurs in the equipment, the intelligent system can quickly issue an alarm and accurately locate the fault point through data analysis. For example, in the dust removal equipment of the mining industry, if a fault such as valve core jamming occurs in the electromagnetic pulse valve, the intelligent system will immediately notify the maintenance personnel and provide detailed fault information, greatly shortening the equipment maintenance time and improving production efficiency.The intelligent transformation of electromagnetic pulse valves has brought higher efficiency, lower costs, and more reliable operation guarantees for industrial cleaning.

Electromagnetic Pulse Valves: Key Equipment for Promoting the Upgrading of the Environmental Protection Industry
The environmental protection industry occupies an increasingly important position in today’s social development. As a key component of environmental protection equipment, electromagnetic pulse valves are promoting the technological upgrading and efficient development of the environmental protection industry.
Picture (DMF-Z-40S Pulse Valve)
Electromagnetic pulse valves have the significant advantage of fast response speed. In some production environments with extremely strict requirements for dust emissions, such as electronic chip manufacturing workshops, electromagnetic pulse valves can respond in a very short time. Once it is detected that the dust accumulation on the surface of the filter bag reaches a certain level, the control system issues an instruction, and the electromagnetic pulse valve can quickly open and complete a pulse injection action within a few milliseconds, timely removing the dust on the filter bag and ensuring that the air quality in the workshop always meets strict standards, providing a clean environment for precision production.
The energy – saving characteristics of electromagnetic pulse valves are also remarkable. The ash – cleaning methods of traditional dust removal equipment often consume a large amount of energy. Modern electromagnetic pulse valves, through optimized design, can precisely control the injection volume and injection time of compressed air. For example, in the small – scale dust removal system used in a food processing factory, the electromagnetic pulse valve adopts intelligent control technology. It automatically adjusts the injection parameters according to the actual working conditions of the filter bag. In this way, while meeting the ash – cleaning requirements, it greatly reduces the waste of compressed air, reducing the energy consumption and operating costs of enterprises.On the path of the environmental protection industry’s continuous pursuit of green and efficient development, the importance of electromagnetic pulse valves has become more prominent. It not only improves the performance and reliability of environmental protection equipment but also provides strong support for enterprises to achieve energy conservation, emission reduction, and sustainable development. With the increasingly strict environmental protection standards, electromagnetic pulse valves will have a broader development space and continue to contribute to the upgrading of the environmental protection industry. -
Electromagnetic Pulse Valves: The Core Power of Industrial Dust Removal Systems
In modern industrial production, dust pollution not only poses a threat to the environment but also seriously endangers the normal operation of production equipment and the health of workers. As a key component of industrial dust removal systems, electromagnetic pulse valves play an irreplaceable role.
The working principle of electromagnetic pulse valves is based on the law of electromagnetic induction. When the electromagnetic coil of an electromagnetic pulse valve is energized, the generated electromagnetic force overcomes the spring force, lifts the valve core, opens the gas passage, and allows compressed air to spray out rapidly. When the electromagnetic coil is de-energized, the electromagnetic force disappears, and the spring force makes the valve core return to its original position, closing the gas passage and stopping the gas injection. This rapid opening and closing action can precisely control the injection time and frequency of compressed air.In the field of industrial dust removal, electromagnetic pulse valves are widely used. Take a cement plant as an example. A large amount of dust is generated during the production process. In a bag filter, the electromagnetic pulse valve emits a pulse jet at regular intervals. The compressed air is sprayed into the interior of the filter bag at high speed. The strong air flow impact causes the filter bag to expand and vibrate instantaneously, shaking off the dust attached to the surface of the filter bag, thus achieving the ash cleaning of the filter bag. In this way, not only can the air permeability of the filter bag be ensured, the high – efficiency operation of the dust collector be maintained, but also the service life of the filter bag can be extended, reducing the operating costs of enterprises.In other industrial fields such as steel plants and thermal power plants, electromagnetic pulse valves also play an important role. They ensure a clean production environment, reduce the erosion of dust on equipment, and improve the safety and stability of production. With the continuous progress of industrial technology, electromagnetic pulse valves are also constantly innovating and developing, moving towards higher performance, more energy – saving, and more intelligent directions to meet the needs of future industrial development. -
Core Principles and Key Role of Dust Removal Electromagnetic Pulse Valves
In modern industrial dust removal systems, electromagnetic pulse valves serve as the “heart components” of pulse bag filters. Their performance directly impacts equipment efficiency and service life. As intelligent switches for compressed air, these valves precisely control filter bag cleaning cycles through commands from pulse controllers, ensuring stable system resistance and optimal operation.
The working principle relies on differential pressure control: when energized, the electromagnetic force moves the spool to open the pressure relief port. This rapidly drops the pressure in the rear chamber, lifting the diaphragm via compressed air for instantaneous jetting. After power-off, the spring resets the spool to close the port, restoring rear chamber pressure and reclosing the diaphragm. This process demands precise diaphragm design and airflow engineering to achieve sub-100ms response times and stable jetting pressure.Typical technical specifications include aluminum alloy bodies for -10°C to 55°C environments, 0.4-0.7MPa operating pressure, and compatibility with AC220V/DC24V power supplies. The diaphragm must resist wear and corrosion, with high-quality models offering over 1 million jetting cycles.Selection criteria depend on dust collector size, air source conditions, and cleaning frequency. Right-angle valves (90° inlet/outlet) suit small-to-medium systems with vertical installations, while submerged valves (integrated into air tanks) provide lower resistance and higher efficiency for fluctuating air pressure scenarios. -
The DMF-Z type Right angle valve
1. Definition and Purpose
- The DMF-Z type Right angle valve is a specialized electromagnetic pulse valve designed for bag-type dust collectors.
- It serves as the compressed air switch in the pulse bag filter’s ash-cleaning system, controlled by a pulse injection controller. Its primary function is to periodically blow air through filter bags (row by row or chamber by chamber) to remove accumulated dust, maintaining the dust collector’s resistance within a set range and ensuring efficient dust removal and collection.
