Product Description:
BFEC electromagnetic pulse valves are flagship products of Shanghai Bag Filtration Equipment Co., Ltd., which is presently known as Shanghai Bag Filter Technology Co., Ltd. The origins of the company trace back to the environmental protection division of Shanghai Carbon Factory. Since 1978, it has been supplying pulse valves and dedusting solutions. In 1997, the company formed a joint venture with U.S. Gore, further enhancing its technological capabilities.
The company holds a significant position in the environmental sector, serving as a standing council member of the China Association of Environmental Protection Industry. It leads the development of one national standard, five industry standards, and five group standards. Additionally, Shanghai Bag Filter Technology owns over 70 intellectual property rights and has earned certifications including CE and PCEC.
A pulse valve functions as the essential "switch" controlling compressed air within a pulse-jet baghouse dust collector. The valve operates by receiving electrical signals from a pulse controller, triggering it to open and close rapidly. This action releases bursts of high-pressure air from the air manifold into the filter bags. The sudden expansion and vibration of the bags help to effectively shake off accumulated dust.
The main valve series offered include several specialized types:
-
DMF-Z Right-Angle Type:
Features a 90° angle between inlet and outlet with a threaded connection. Its compact design allows for easy maintenance, making it well-suited for small to medium dust collectors.
-
ZF Right-Angle Flanged Type:
Equipped with flanged inlet and outlet connections, this type simplifies the installation process even further.
-
DMF-Y Submerged (Embedded) Type:
Installed directly on the air manifold, this valve offers superior flow performance and reduced pressure loss, ideal for systems with low-pressure air sources.
-
DMF-T In-Line Type:
Designed with 180° straight-through ports to facilitate smooth airflow.
-
Large-Diameter Valves (8″–16″):
Engineered for large-scale dedusting applications requiring higher capacity valves.
Features:
Technical Specifications:
The device operates effectively within a working pressure range of 0.1 to 0.86 MPa, with a recommended pressure between 0.3 and 0.6 MPa. It is designed to use clean and dry compressed air as the medium. Available voltage options include DC 24V, AC 36V, AC 110V, and AC 220V. The product features an IP65 protection rating and can function reliably in environments with relative humidity up to 85%.
Optional Configurations:
For applications in hazardous environments, an explosion-proof coil option is available. Additionally, a square rubber gasket can be selected for enhanced sealing performance, catering to specific installation requirements.
Advanced Processing Techniques:
The threads are extruded to be three to four times stronger than ordinary threads, ensuring durability and resistance to stripping even after repeated maintenance. Surfaces undergo vibration polishing and anti-corrosion treatments to improve longevity. Furthermore, automatic lathe machining is employed to guarantee consistent and high-quality manufacturing standards.

Applications:
Dust control plays a crucial role in various industrial sectors such as steel and metallurgy, thermal power generation, cement production, chemical processing, construction, and waste incineration. Effective dust management ensures safer working environments and compliance with environmental regulations.
One of the primary methods employed for dust removal is pulse cleaning technology. This technique is widely used for cleaning different types of filters, including bag filters (both filter bags and cages), cartridge filters, ceramic filters, as well as sintered metal fiber filters. The pulse cleaning mechanism helps maintain filter efficiency and prolongs their operational lifespan.
In addition, large off-line long-bag collectors are extensively utilized in industrial settings. These collectors are especially effective in fly-ash collection at power plants and in handling heavy dust loads typically found in metallurgy applications. For these purposes, submerged large-diameter valves are highly recommended due to their ability to provide strong jetting force and ensure stable performance even when operating under low-pressure air supply conditions.
