Analysis of the Function of Diaphragms in Electromagnetic Pulse Valves
In the complex pneumatic systems of modern industry, although the diaphragms of electromagnetic pulse valves may seem insignificant, they play a crucial role. The quality of their performance directly affects the operational efficiency and stability of the entire system. A thorough exploration of the functions of diaphragms in electromagnetic pulse valves helps us better understand the operating mechanisms of industrial equipment.From the perspective of working principles, the diaphragm of an electromagnetic pulse valve is the core component for achieving precise control. When the electromagnetic coil of the electromagnetic pulse valve is energized, an electromagnetic force is generated, attracting the diaphragm to overcome the spring force and back pressure. The diaphragm deforms instantaneously, opening the valve port, allowing compressed air to rapidly pass through the pulse valve into the blowpipe and jet out at high speed in an extremely short time, performing a powerful cleaning of the filter bags in dust collectors. When the electromagnetic coil is de-energized, the electromagnetic force disappears, and the diaphragm quickly resets under the action of the spring force and back pressure, closing the valve port and cutting off the air flow. In this process, the diaphragm acts like an accurate “commander,” controlling the on-off of the air flow through its own deformation and resetting, achieving precise operation of the pulse injection.In dust collection systems, the role of the diaphragm in electromagnetic pulse valves is particularly critical. Take bag dust collectors as an example. As the dust collection work continues, dust will continuously adhere to the surface of the filter bags, increasing resistance and affecting dust collection efficiency. At this time, the pulse injection system controlled by the diaphragm of the electromagnetic pulse valve comes into play. Through an instantaneous high-pressure injection, it removes the dust on the surface of the filter bags, restoring the air permeability of the filter bags and ensuring the long-term stable operation of the dust collector. The rapid response and reliable sealing performance of the diaphragm ensure that each injection is accurate and efficient, extending the service life of the filter bags and reducing maintenance costs. Statistics show that in dust collection systems using electromagnetic pulse valve diaphragms with good performance, the replacement cycle of filter bags can be extended by 30% – 50%.In addition to the dust collection field, diaphragms of electromagnetic pulse valves are also widely used in other industrial scenarios. In industries with extremely high hygiene requirements, such as food and pharmaceuticals, pneumatic conveying systems often use electromagnetic pulse valves to control the conveying of materials. The good sealing and corrosion resistance of the diaphragm can effectively prevent material leakage and contamination, ensuring product quality and safety. In automated production lines of industries such as automotive manufacturing and mechanical processing, diaphragms of electromagnetic pulse valves are used to control the actions of cylinders, enabling precise grasping, handling, and assembly of components. Their fast switching actions and stable performance improve the degree of automation and production efficiency of the production lines.With its unique function of controlling air flow, the diaphragm of the electromagnetic pulse valve plays an indispensable role in the industrial field. With the continuous development of industrial technology, the performance requirements for diaphragms of electromagnetic pulse valves are also increasing day by day. In the future, they will develop towards a more efficient, reliable, and intelligent direction, continuing to escort industrial production. -

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.

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. -

- Energy Savings: Their rapid actuation reduces jetting time, achieving 15%+ compressed air savings through optimized diaphragm design.
- Installation Flexibility: Right-angle valves support threaded/flanged connections for versatile layouts, while submerged valves require custom air tank interfaces ideal for new installations or large-scale retrofits.
Selection Recommendations- Unstable Pressure Environments: Prioritize submerged valves with their 0.3-0.8MPa pressure tolerance.
- Space Constraints: Right-angle valves’ compact design suits small systems or renovation projects.
- Long-Term 经济性: Submerged valves’ energy efficiency and extended diaphragm life (2+ million cycles) make them ideal for continuous industrial operations.

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.
