Product Description:
The Shanghai Bag Fittings SBFEC DMF Series represents a line of high-performance pulse jet diaphragm valves specially designed for reverse pulse filter cleaning in industrial dust collectors and baghouse systems. These valves act as the compressed air switches in pulse bag dust collector setups, being precisely controlled by output signals from a pulse injection controller. This allows them to deliver powerful, instantaneous air pulses that effectively clean the filters.
The DMF Series offers multiple configurations tailored to meet diverse installation needs:
- DMF-Z Series (Right Angle Valves) – These valves feature a 90° angle between the inlet and outlet, making them ideal for installation between the air manifold and blow pipe. They come 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 installed directly into the air manifold (air tank). They provide superior flow characteristics and lower pressure loss, which is particularly advantageous for applications with low air pressure. Available sizes range from 1″ to 5″ (models DMF-Y-25 through DMF-Y-120S).
- DMF-ZM Series (Right Angle with Nut) – This series retains the right-angle design of the Z series but includes fixing nuts on both inlet and outlet ports, facilitating easier installation and more convenient handling.
- DMF-T Series (Straight-Through Valves) – Featuring inlet and outlet ports aligned on the same centerline, these valves ensure smooth airflow and are well-suited to air tank pulse dust collectors.
- DMF-FS Series (Flanged Valves) – Designed with flanged connections, these valves are ideal for applications requiring secure, leak-proof mounting.
Constructed from die-cast aluminum alloy with a robust coating, the valve bodies combine durability with lightweight properties. The diaphragms come in various materials, including standard NBR, FKM (fluororubber), and other specialized options designed for high-temperature environments. These valves operate efficiently within a working pressure range of 0.1 to 0.8 MPa (1 to 8 bar), supporting multiple voltage inputs such as DC24V, AC110V, and AC220V. Impressively, the diaphragm's service life exceeds one million pulse cycles or up to five years of operation.
Globally trusted across various industries, the Shanghai Bag Fittings SBFEC DMF Series valves deliver dependable, high-volume pulse jets that enhance dust removal efficiency and extend the lifespan of filter bags. Backed by 18 patents related to baghouse dust collection technology, Shanghai Bag Fittings stands as one of China’s most comprehensive manufacturers of dust collector accessories.
Features:
Multiple Configuration Options
The product offers various design configurations to suit different installation needs. These include the right-angle (DMF-Z), submerged (DMF-Y), right-angle with nut (DMF-ZM), straight-through (DMF-T), and flanged (DMF-FS) designs. Each configuration is tailored to optimize performance in specific applications.
Right-Angle Design (DMF-Z/ZM)
Featuring a 90° inlet-outlet setup, the right-angle design allows compact installation between the air manifold and blow pipe. The nut-type variant (DMF-ZM) includes fixing nuts on both ports, enabling quick, tool-free installation and simplifying maintenance procedures.
Submerged Design (DMF-Y)
In the submerged design, the valve seat is embedded directly into the air manifold. This arrangement reduces pressure loss and enhances flow characteristics, making it particularly suitable for low-pressure applications.
Straight-Through Design (DMF-T)
The straight-through design aligns the inlet and outlet along the same centre line, providing smooth and unrestricted airflow. This configuration is ideal for applications requiring minimal flow disruption.
Durable Construction and Material Options
The valve features a durable aluminium alloy body that is die-cast and coated with a wear-resistant finish to ensure a long service life. Multiple diaphragm materials are available, including NBR as the standard option and FKM (fluororubber) for applications demanding high temperature and chemical resistance.
Operational Specifications
This valve operates efficiently over a wide pressure range from 0.1 to 0.8 MPa (1 to 8 bar). It supports multiple voltage options such as DC24V, AC110V, and AC220V (50/60Hz), allowing flexibility in power supply requirements.
Designed for longevity, the diaphragm life exceeds one million pulse cycles or up to five years of service. The valve can operate within a wide temperature range, from -25°C to +80°C as standard, with high-temperature versions available up to +230°C.
Additionally, it boasts an IP65 protection rating, ensuring that it is dust-tight and protected against water jets. The valve also features low power consumption, making it energy-efficient and cost-effective to operate.
