Product Description:
BFEC electromagnetic pulse valves represent the flagship products of Shanghai Bag Filtration Equipment Co., Ltd., which is currently known as Shanghai Bag Filter Technology Co., Ltd. The company traces its origins back to the environmental protection department of Shanghai Carbon Factory. Since 1978, it has been providing pulse valves and dedusting products. In 1997, it established a joint venture with the U.S.-based company Gore. As a standing council member of the China Association of Environmental Protection Industry, the company has played a pivotal role in the development of industry standards, having led the formulation of one national standard, five industry standards, and five group standards. It holds more than 70 intellectual property rights and has secured CE and PCEC certifications.
The pulse valve functions as the essential "switch" for compressed air within pulse-jet baghouse dust collectors. It operates through electrical signals sent from the pulse controller, enabling the valve to open and close instantaneously. This action releases high-pressure air pulses from the air manifold into the filter bags, which causes rapid expansion and vibration of the bags to effectively dislodge accumulated dust particles.
The main product series offered include:
-
DMF-Z Right-Angle Type:
Featuring a 90-degree angle between the inlet and outlet, this valve has a threaded connection that is compact and easy to maintain, making it well-suited for small and medium-sized collectors.
-
ZF Right-Angle Flanged Type:
Equipped with flanged inlet and outlet connections, this type provides even easier installation.
-
DMF-Y Submerged (Embedded) Type:
This valve is mounted directly onto the air manifold, offering superior flow characteristics and lower pressure loss, which is ideal for systems operating with low-pressure air sources.
-
DMF-T In-Line Type:
Designed with 180-degree straight-through ports, this valve ensures smooth airflow.
-
Large-Diameter Valves (8″–16″):
These valves are specifically designed for large-scale dedusting systems requiring higher capacity.
Features:
Technical Specifications:
The device operates under a working pressure range of 0.1 to 0.86 MPa, with a recommended pressure between 0.3 and 0.6 MPa. It functions using clean, dry compressed air as the medium. Multiple voltage options are available, including DC 24V, AC 36V, AC 110V, and AC 220V. The unit is rated with an IP65 protection class, making it suitable for various environments. Additionally, it performs reliably in conditions where the relative humidity does not exceed 85%.
Optional Configurations:
For enhanced safety in hazardous environments, an explosion-proof coil is available. Moreover, a square rubber gasket can be added to improve sealing and robustness, providing further customization to meet specific operational requirements.
Advanced Processing:
The threads are extruded to be three to four times stronger than typical threads, significantly improving durability and resistance to stripping, even after repeated maintenance. Surfaces undergo vibration polishing and anti-corrosion treatment to extend lifespan and maintain appearance. Consistent high quality is ensured through automatic lathe machining processes.

Applications:
Dust control plays a vital role across various industries including steel and metallurgy, thermal power generation, cement manufacturing, chemical processing, construction, and waste incineration. Effective management of dust emissions ensures cleaner environments and compliance with regulatory standards in these sectors.
One of the commonly used methods for maintaining filter efficiency is pulse cleaning. This technique is applied to different types of filters such as bag filters—which include filter bags and cages—cartridge filters, ceramic filters, and sintered metal fiber filters. Pulse cleaning helps to remove accumulated dust and maintain optimal airflow through the filtration system.
In applications involving large-scale filtration, such as long-bag offline collectors and fly-ash collection systems in power plants, specialized equipment is essential. Particularly in heavy-dust environments found in metallurgy, the use of submerged large-diameter valves is recommended. These valves offer a powerful jetting force and ensure stable operation even when supplied with low-pressure air, making them highly effective for demanding filtration tasks.
