Product Description:
BFEC electromagnetic pulse valves are flagship products manufactured by Shanghai Bag Filtration Equipment Co., Ltd., which is 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 since 1978. In 1997, it entered into a joint venture partnership with U.S. Gore to enhance its product offerings. As a standing council member of the China Association of Environmental Protection Industry, the company plays a key role in developing industry regulations, having led the formulation of one national standard, five industry standards, and five group standards. Moreover, it holds more than 70 intellectual property rights and has obtained CE and PCEC certifications.
The pulse valve functions as a critical component in pulse-jet baghouse dust collectors, essentially serving as the "switch" for compressed air. It operates by responding to electrical signals from the pulse controller, quickly opening and closing to release bursts of high-pressure air from the air manifold. These pulses enter the filter bags, causing them to rapidly expand and vibrate, which effectively dislodges the accumulated dust particles. BFEC offers several main valve series designed to meet various application needs:
- DMF-Z Right-Angle Type: Features a 90-degree angle between the inlet and outlet with a threaded connection, making it compact and easy to maintain. This model is particularly suited for small to medium-sized dust collectors.
- ZF Right-Angle Flanged Type: Equipped with flanged inlet and outlet connections, this valve offers even simpler installation compared to threaded types.
- DMF-Y Submerged (Embedded) Type: This valve is designed to be installed directly onto the air manifold, providing excellent flow characteristics and reduced pressure loss. It is ideal for systems utilizing low-pressure air sources.
- DMF-T In-Line Type: Featuring 180-degree straight-through ports, this valve ensures smooth airflow and optimal performance.
- Large-Diameter Valves (8″–16″): These valves are manufactured for use in large-scale dedusting systems requiring high capacity airflow.
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 is designed to work using clean and dry compressed air as the medium. Multiple power options are available, including DC 24V, AC 36V, AC 110V, and AC 220V. Additionally, the product features an IP65 protection rating and can operate effectively in environments where the relative humidity does not exceed 85%.
Optional Configurations
For applications in hazardous areas, an explosion-proof coil is available as an optional upgrade. Furthermore, a square rubber gasket can be added to enhance sealing and durability according to specific requirements.
Advanced Processing
The product is manufactured with extruded threads that are three to four times stronger than standard threads, which significantly improves resistance to stripping even after multiple maintenance cycles. The surfaces undergo vibration polishing combined with anti-corrosion treatments to ensure longevity and reliability. Consistent quality is maintained through the use of automatic lathe machining processes.

Applications:
Dust control is a critical process in several industries such as steel and metallurgy, thermal power generation, cement production, chemical manufacturing, construction, and waste incineration. Effective dust management ensures cleaner environments and compliance with environmental regulations.
One of the widely used methods for maintaining filter efficiency is pulse cleaning. This technique is applied to various types of filters, including bag filters (which consist of filter bags and cages), cartridge filters, ceramic filters, and sintered metal fiber filters. Pulse cleaning helps to dislodge accumulated dust and maintain optimal filtration performance.
In large-scale applications, such as long-bag off-line collectors and fly-ash collection systems in power plants, as well as in heavy-dust conditions typical of metallurgy, specialized equipment is required. Submerged large-diameter valves are highly recommended in these scenarios due to their powerful jetting force and ability to operate steadily under low-pressure air supply, providing reliable and efficient cleaning performance.
