Product Description:
The Shanghai Bag Fittings SBFEC DMF Series represents a range of high-performance pulse jet diaphragm valves, specifically engineered for reverse pulse filter cleaning in industrial dust collectors and baghouse systems. These valves function as the compressed air switch within pulse bag dust collector systems, controlled by output signals from a pulse injection controller. This enables them to deliver instantaneous, high-energy air pulses, ensuring effective and efficient filter cleaning.
The DMF Series is available in multiple configurations, tailored to meet diverse installation needs:
- DMF-Z Series (Right Angle Valves): Featuring a 90° angle between the inlet and outlet, these valves are suitable for installation between the air manifold and the blow pipe. They are offered in sizes ranging from 3/4″ to 3″ (models DMF-Z-20 through DMF-Z-76S).
- DMF-Y Series (Submerged Valves): Also referred to as embedded valves, these are mounted directly into the air manifold (air tank). Their design delivers superior flow characteristics and minimizes pressure loss, making them ideal for low air pressure applications. Sizes available range from 1″ to 5″ (models DMF-Y-25 through DMF-Y-120S).
- DMF-ZM Series (Right Angle with Nut): This series shares the right-angle design of the Z series but includes fixing nuts on both the inlet and outlet ports, allowing for easier installation and increased convenience during use.
- DMF-T Series (Straight-Through Valves): Designed with the inlet and outlet aligned on the same center line, this configuration promotes smooth airflow and is well-suited for air tank pulse dust collectors.
- DMF-FS Series (Flanged Valves): Featuring a flanged connection design, these valves are intended for applications that require secure and leak-proof mounting.
The valve bodies are manufactured from die-cast aluminium alloy, coated for enhanced durability. Regarding diaphragm materials, options include NBR (standard), FKM (fluororubber), as well as other specialized materials for high-temperature environments. These valves operate efficiently within a pressure range of 0.1 to 0.8 MPa (1 to 8 bar), and they support various voltage options such as DC24V, AC110V, and AC220V. Notably, the diaphragm service life exceeds one million pulse cycles or up to five years under typical operating conditions.
Trusted by industries across the globe, the Shanghai Bag Fittings SBFEC DMF Series valves provide reliable, high-flow pulse jets that contribute to effective dust removal and prolonged filter bag lifespan. The company holds 18 patents related to baghouse dust collection products and is recognized as one of China’s most comprehensive manufacturers of dust collector accessories.
Features:
Multiple Configuration Options
The product is available in various configurations to suit different installation needs. These include right-angle (DMF-Z), submerged (DMF-Y), right-angle with nut (DMF-ZM), straight-through (DMF-T), and flanged (DMF-FS) designs.
Right-Angle Design (DMF-Z/ZM)
The right-angle configuration offers a 90° inlet-outlet setup, making it ideal for compact installations between the air manifold and blow pipe. This design helps save space without compromising performance.
Submerged Design (DMF-Y)
Featuring a valve seat embedded directly into the air manifold, the submerged design reduces pressure loss and enhances flow characteristics. It is particularly suitable for low-pressure applications due to its efficient layout.
Straight-Through Design (DMF-T)
In this design, the inlet and outlet are aligned along the same centerline, allowing for smooth and unrestricted airflow. This is beneficial in applications where maintaining consistent flow is critical.
Nut-Type Connection (DMF-ZM)
The nut-type connection includes fixing nuts on both ports, enabling quick, tool-free installation and simplifying maintenance procedures. This feature reduces downtime and improves usability.
