Product Description:
BFEC electromagnetic pulse valves represent the flagship products of Shanghai Bag Filtration Equipment Co., Ltd., currently known as Shanghai Bag Filter Technology Co., Ltd. The company has its roots in the environmental protection department of Shanghai Carbon Factory and began supplying pulse valves and dust removal solutions back in 1978. In 1997, it established a joint venture with U.S.-based Gore. Today, the company is a standing council member of the China Association of Environmental Protection Industry. It has played a leading role in the creation of one national standard, five industry standards, and five group standards. Moreover, the company holds over 70 intellectual property rights and is certified by CE and PCEC.
A pulse valve functions as the "switch" for compressed air within a pulse-jet baghouse dust collector. It operates under electrical signals sent from the pulse controller and opens or closes instantaneously. This action releases high-pressure air from the air manifold in short bursts which enter the filter bags. The sudden surge of air causes the bags to rapidly expand and vibrate, effectively dislodging the accumulated dust.
The main product series offered by the company include:
- DMF-Z Right-Angle Type: Designed with a 90-degree angle between the inlet and outlet, this type features a threaded connection. Its compact size makes it easy to maintain, making it an excellent choice for small and medium-sized collectors.
- ZF Right-Angle Flanged Type: Equipped with flanged inlet and outlet connections, this model simplifies installation further.
- DMF-Y Submerged (Embedded) Type: This valve is mounted directly onto the air manifold. It offers superior flow characteristics and lower pressure loss, making it ideal for applications using low-pressure air sources.
- DMF-T In-Line Type: Featuring 180-degree straight-through ports, this type ensures smooth airflow through the valve.
- Large-Diameter Valves (8″–16″): These valves are designed for use in large-scale dedusting systems requiring higher capacity.
Features:
Technical Specifications: The device operates within a working pressure range of 0.1 to 0.86 MPa, with a recommended pressure between 0.3 and 0.6 MPa. It uses clean, dry compressed air as the working medium. Power supply options include DC 24V, AC 36V, AC 110V, and AC 220V. The unit is designed with an IP65 protection rating, making it dust-tight and protected against water jets. It is suitable for environments with relative humidity levels up to 85%.
Optional Features: For use in hazardous environments, an explosion-proof coil is available. Additionally, a square rubber gasket can be included to enhance sealing performance, providing more versatility depending on the application requirements.
Advanced Manufacturing Techniques: The product’s threads are extruded to be three to four times stronger than standard threads, which prevents stripping even after repeated maintenance. The surfaces undergo vibration polishing and anti-corrosion treatment to ensure durability. Precision is maintained through automatic lathe machining, guaranteeing consistent quality across units.

Applications:
Dust control is a crucial aspect in various industries such as steel and metallurgy, thermal power generation, cement production, chemical processing, construction, and waste incineration. Effective dust management ensures a cleaner environment and enhances operational safety across these sectors.
One of the key methods used for maintaining filter cleanliness is pulse cleaning. This technique is applied to a variety of filters including bag filters — consisting of filter bags and cages — cartridge filters, ceramic filters, and sintered metal fiber filters. Pulse cleaning helps in removing accumulated dust, thereby improving filter efficiency and prolonging their service life.
In large-scale applications, such as long-bag off-line collectors, fly-ash collection systems in power plants, and heavy dust environments typically found in metallurgy, specialized equipment is necessary. Submerged large-diameter valves are highly recommended in these scenarios because they offer a powerful jetting force while maintaining stable operation even with a low-pressure air supply, making them ideal for rigorous dust control demands.
