DMF-T-25 DMF-T-40S DMF-T-50S Shanghai Bag Fitting 1/1.5/2 Inch Straight Type

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.
