Product Description:
The Shanghai Bag Fittings SBFEC DMF Series represents a range of high-performance pulse jet diaphragm valves, specifically designed for reverse pulse filter cleaning in industrial dust collectors and baghouse systems. These valves act as the compressed air switch within pulse bag dust collector setups, controlled by output signals from a pulse injection controller. Their function is to produce instantaneous, high-energy air pulses that ensure effective cleaning of the filter elements.
To accommodate diverse installation needs, the DMF Series comes in several configurations:
- DMF-Z Series (Right Angle Valves): These feature a 90° angle between the inlet and outlet ports, making them suitable for installation between the air manifold and the blow pipe. They are available in sizes ranging from 3/4″ to 3″ (models DMF-Z-20 through DMF-Z-76S).
- DMF-Y Series (Submerged Valves): Also known as embedded valves, these are directly mounted into the air manifold (air tank). They offer superior flow characteristics and reduced pressure loss, making them ideal for low air pressure environments. Sizes offered range from 1″ to 5″ (models DMF-Y-25 through DMF-Y-120S).
- DMF-ZM Series (Right Angle with Nut): Maintaining the right-angle configuration of the Z series, this variant features fixing nuts on both the inlet and outlet ports to simplify installation and enhance ease of use.
- DMF-T Series (Straight-Through Valves): With inlet and outlet aligned on the same centerline, these valves promote smooth airflow and are well-suited for air tank pulse dust collectors.
- DMF-FS Series (Flanged Valves): Designed with flanged connections, these valves provide secure and leak-proof mounting for applications demanding robust attachment.
The valve bodies are manufactured from die-cast aluminium alloy, coated for durability. Diaphragm materials come in various options including NBR (standard), FKM (fluororubber), and specialized materials for high-temperature environments. These valves function effectively within a working pressure range of 0.1 to 0.8 MPa (1 to 8 bar) and support multiple voltage inputs such as DC24V, AC110V, and AC220V. The diaphragm’s service life surpasses 1 million pulse cycles or lasts up to 5 years under normal conditions.
Trusted by industries worldwide, the Shanghai Bag Fittings SBFEC DMF Series valves provide reliable, high-flow pulse jets that contribute to efficient dust removal and prolonged filter bag lifespan. Backed by 18 patents related to baghouse dust collection technologies, Shanghai Bag Fittings is recognized as one of China’s most comprehensive manufacturers of dust collector accessories.
Features:
There are multiple configuration options available for this product, including right-angle (DMF-Z), submerged (DMF-Y), right-angle with nut (DMF-ZM), straight-through (DMF-T), and flanged (DMF-FS) designs. These variations allow for flexible installation to meet different requirements and applications.
The right-angle design models (DMF-Z and DMF-ZM) feature a 90° inlet-outlet configuration. This compact layout is ideal for installations between the air manifold and blow pipe, saving space without compromising performance.
The submerged design (DMF-Y) integrates the valve seat directly into the air manifold. This approach reduces pressure loss and improves flow characteristics, making it especially suitable for low-pressure applications.
The straight-through design (DMF-T) aligns the inlet and outlet on the same centerline. This configuration ensures a smooth and unrestricted airflow, enhancing overall efficiency.
For fast and hassle-free setup, the nut-type connection (DMF-ZM) includes fixing nuts on both ports. This design enables tool-free installation and simplifies maintenance procedures.
Built for durability, the valve body is made of die-cast aluminium alloy with a wear-resistant coating. This construction guarantees a long service life even in demanding environments.
Multiple diaphragm materials are offered to meet different operational needs. The standard option uses NBR, while a fluororubber (FKM) variant is available for applications requiring high temperature and chemical resistance.
The valve operates effectively within a wide pressure range, from 0.1 to 0.8 MPa (1 to 8 bar), accommodating various system requirements.
Voltage options are versatile as well, supporting DC24V, AC110V, and AC220V at 50/60Hz frequency to suit different power supply setups.
With a diaphragm life exceeding one million pulse cycles or up to five years, this product offers exceptional longevity and reliability.
It supports a broad temperature range, with a standard operating window from -25°C to +80°C and a high-temperature version that can withstand up to +230°C.
The valve’s IP65 protection rating ensures it is dust-tight and shielded against water jets, providing dependable performance in harsh conditions.
Additionally, its low power consumption contributes to energy efficiency, helping to reduce overall operating costs.
