Product Description:
BFEC electromagnetic pulse valves represent the core offerings 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 providing pulse valves and dedusting solutions in 1978. In 1997, it formed a joint venture with U.S. Gore, marking a significant milestone in its development.
As a key player in the environmental protection industry, the company serves as a standing council member of the China Association of Environmental Protection Industry. It has taken a leading role in the formulation of one national standard, five industry standards, and five group standards. Furthermore, it holds over 70 intellectual property rights and has obtained both CE and PCEC certifications, underscoring its commitment to quality and innovation.
The pulse valve functions as the essential “switch” for compressed air within a pulse-jet baghouse dust collector. It operates through electrical signals from the pulse controller, which cause it to open and close instantaneously. When activated, the valve releases bursts of high-pressure air from the air manifold into the filter bags. This rapid air pulse causes the bags to expand and vibrate, effectively dislodging the accumulated dust.
BFEC offers several main series of pulse valves to meet different application needs:
- DMF-Z Right-Angle Type: Features a 90° angle between the inlet and outlet, with a threaded connection that is compact and easy to maintain, making it well-suited for small and medium-sized dust collectors.
- ZF Right-Angle Flanged Type: Equipped with flanged inlets and outlets, this type enables even easier installation.
- DMF-Y Submerged (Embedded) Type: Installed directly on the air manifold, this valve boasts superior flow characteristics and lower pressure loss, ideal for systems using low-pressure air sources.
- DMF-T In-Line Type: Offers 180° straight-through ports to ensure smooth airflow.
- Large-Diameter Valves (8″–16″): Designed for large-scale dedusting systems, these valves accommodate higher capacity requirements.
Features:
Technical Specifications: The working pressure ranges from 0.1 to 0.86 MPa, with a recommended operational range of 0.3 to 0.6 MPa. The device uses clean, dry compressed air as the medium for operation. It offers multiple voltage options including DC 24V, AC 36V, AC 110V, and AC 220V. The product is rated with an IP65 protection level, suitable for various environments, and functions reliably in relative humidity conditions up to 85%.
Optional Configurations: For enhanced safety in hazardous areas, an explosion-proof coil can be selected. Additionally, a square rubber gasket is available as an optional accessory to improve sealing and durability.
Advanced Processing Techniques: The threads are extruded to be three to four times stronger than standard threads, providing resistance to stripping even after multiple maintenance cycles. The surfaces undergo vibration polishing and anti-corrosion treatment to enhance longevity. Furthermore, automatic lathe machining is employed to maintain consistent quality across all units.

Applications:
Dust control is a critical aspect in various industries such as steel and metallurgy, thermal power generation, cement manufacturing, chemical processing, construction, and waste incineration. Effective dust management ensures cleaner working environments and compliance with environmental regulations.
One common method employed is the pulse cleaning technique, which is used for different types of filters including bag filters with filter bags and cages, cartridge filters, ceramic filters, as well as sintered metal fiber filters. This method helps maintain filter efficiency by periodically removing accumulated dust particles.
In large-scale applications, such as long-bag off-line collectors and fly-ash collection systems in power plants, as well as heavy-dust environments found in metallurgical processes, specialized equipment is necessary. Submerged large-diameter valves are highly recommended for these settings due to their ability to deliver strong jetting force and ensure stable operation even when supplied with low-pressure air.
