Product Description:
BFEC electromagnetic pulse valves are flagship products manufactured by Shanghai Bag Filtration Equipment Co., Ltd., now known as Shanghai Bag Filter Technology Co., Ltd. The company traces its roots back to the environmental protection division of Shanghai Carbon Factory and started providing pulse valves and dedusting solutions in 1978. Later, in 1997, it formed a joint venture with the U.S.-based company Gore. The enterprise holds a prominent position as a standing council member of the China Association of Environmental Protection Industry. It has played a leading role in developing numerous standards, including one national standard, five industry standards, and five group standards. Additionally, the company boasts over 70 intellectual property rights and possesses both CE and PCEC certifications.
A pulse valve functions as the essential "switch" for compressed air in pulse-jet baghouse dust collectors. Controlled by electrical signals from the pulse controller, the valve rapidly opens and closes, releasing bursts of high-pressure air from the air manifold into the filter bags. This sudden pulse causes the bags to expand and vibrate, effectively dislodging accumulated dust particles and ensuring efficient filtration.
The main series of BFEC pulse valves includes several types, each designed for specific applications:
- DMF-Z Right-Angle Type: Featuring a 90° angle between the inlet and outlet with threaded connections, this model offers a compact design that simplifies maintenance. It is particularly suitable for small to medium-sized collectors.
- ZF Right-Angle Flanged Type: Equipped with flanged inlet and outlet connections, this valve type allows for even easier installation processes.
- DMF-Y Submerged (Embedded) Type: This valve is mounted directly on the air manifold, providing superior flow characteristics and reduced pressure loss, making it ideal for systems with low-pressure air sources.
- DMF-T In-Line Type: Designed with 180° straight-through ports, this valve ensures smooth airflow through the system.
- Large-Diameter Valves (8″–16″): These valves are intended for large-scale dedusting systems that require handling higher volumes of airflow.
Features:
Technical Specifications: The device operates efficiently 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 with clean, dry compressed air as the medium. Various voltage options are available, including DC 24V, AC 36V, AC 110V, and AC 220V. The unit is protected to an IP65 rating, making it dust-tight and resistant to water jets. It can function reliably in environments with relative humidity up to 85%.
Optional Configurations: For use in hazardous environments, an explosion-proof coil is available. Additionally, the product can be equipped with a square rubber gasket to enhance sealing and durability under specific conditions.
Advanced Processing: The product features extruded threads that are three to four times stronger than standard threads, significantly reducing the risk of stripping even after multiple maintenance cycles. Surfaces undergo vibration polishing and anti-corrosion treatment to ensure longevity and aesthetic quality. Moreover, the use of automatic lathe machining guarantees consistent precision and reliability across all units.

Applications:
Dust control is essential in various industries such as steel and metallurgy, thermal power generation, cement production, chemical manufacturing, construction, and waste incineration. Effective dust management helps maintain air quality and ensures compliance with environmental regulations.
One common method for maintaining filtration systems is pulse cleaning. This technique is widely used for different types of filters, including bag filters (both filter bags and cages), cartridge filters, ceramic filters, and sintered metal fiber filters. Pulse cleaning helps to remove dust buildup and maintain the efficiency of these filtration devices.
For large-scale dust collection, especially in applications like long-bag off-line collectors and fly-ash collection in power plants, specialized equipment is required. Heavy-dust environments in metallurgy also demand robust solutions. In these cases, submerged large-diameter valves are highly recommended due to their ability to provide strong jetting force and stable operation, even under conditions of low-pressure air supply.
Support and Services:
Our Pulse Jet Valves are designed to provide reliable and efficient performance in dust collector and pneumatic conveying systems. For optimal operation, ensure that the valves are installed according to the manufacturer's guidelines, with proper alignment and secure connections.
Regular maintenance is essential to extend the lifespan of the Pulse Jet Valves. Inspect the valves periodically for any signs of wear, damage, or leakage. Clean the valve components to prevent the buildup of dust and debris, which can impair functionality.
If you experience any issues with the Pulse Jet Valves, such as air leakage, delayed response, or failure to operate, check the solenoid coil and diaphragm for proper function and replace any faulty parts as necessary. Ensure that the supply air pressure meets the specified requirements and that the control system signals are correctly configured.
For detailed troubleshooting, maintenance schedules, and replacement parts information, please refer to the product manual provided with your Pulse Jet Valves. Proper adherence to the guidelines will help maintain the performance and reliability of your system.
