Shanghai Bag Fitting DMF-Y Series Full Size 1"-4.5" Submerged Pulse Valve DMF-Y25/40S/50S/62S/76S/102SA/120S Solenoid Valves Industrial Baghouse Dust Cleaning

Product Description:

The Shanghai Bag Fittings SBFEC DMF Series represents a line of high-performance pulse jet diaphragm valves specifically designed 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 setups, being operated by output signals from a pulse injection controller to provide rapid, high-energy air pulses that ensure effective cleaning of filtration elements.

The DMF Series is available in multiple configurations tailored to accommodate a variety of installation demands:

• DMF-Z Series (Right Angle Valves): These valves feature a 90° angle between the inlet and outlet, making them suitable for placement between the air manifold and the blow pipe. They come in sizes ranging from 3/4″ to 3″, covering models DMF-Z-20 through DMF-Z-76S.
• DMF-Y Series (Submerged Valves): Also known as embedded valves, this series is installed directly into the air manifold (air tank). This design promotes superior airflow characteristics with minimized pressure loss, ideal for applications involving low air pressure. Available sizes range from 1″ to 5″, encompassing DMF-Y-25 through DMF-Y-120S models.
• DMF-ZM Series (Right Angle with Nut): Sharing the right-angle design of the Z series, these valves include fixing nuts on both inlet and outlet ports. This addition facilitates easier and more convenient installation.
• DMF-T Series (Straight-Through Valves): These valves have the inlet and outlet ports aligned along the same centerline, enabling smooth airflow. They are especially suitable for air tank pulse dust collector systems.
• DMF-FS Series (Flanged Valves): Designed with a flanged connection, these valves provide secure and leak-proof mounting for applications demanding reliable sealing.

Constructed from die-cast aluminium alloy and coated for durability, the valve bodies offer robust performance under demanding conditions. The diaphragms are made from various materials to suit different operating environments, with NBR (standard), FKM (fluororubber), and additional options available for high-temperature scenarios. These valves operate efficiently within a working pressure range of 0.1 to 0.8 MPa (1 to 8 bar) and support a variety of voltage inputs, including DC24V, AC110V, and AC220V. The diaphragm’s service life impressively exceeds one million pulse cycles or can last up to five years under normal use.

Globally trusted by numerous industries, the Shanghai Bag Fittings SBFEC DMF Series valves reliably deliver high-flow pulse jets that enhance dust removal efficiency and prolong the life of filter bags. The company has secured 18 patents related to baghouse dust collection technologies and is recognized as one of China’s most comprehensive manufacturers of dust collector accessories.

Features:

The product offers a variety of 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.

Featuring a 90° inlet-outlet configuration, the right-angle design allows for compact installation between the air manifold and the blow pipe, optimizing space utilization.

In this design, the valve seat is embedded directly into the air manifold. This setup reduces pressure loss, enhances flow characteristics, and is particularly suitable for low-pressure applications.

With both inlet and outlet aligned on the same centerline, the straight-through design ensures smooth and unrestricted airflow, ideal for applications requiring efficient air passage.

This design incorporates fixing nuts on both ports, allowing for quick installation without the need for tools and facilitating easy maintenance.

The valve body is made from durable die-cast aluminium alloy, coated with a wear-resistant layer to ensure long service life even under demanding conditions.

Various diaphragm materials are available, including standard NBR and FKM fluororubber options, the latter providing enhanced resistance to high temperatures and chemicals.

The valve operates effectively within a wide pressure range from 0.1 to 0.8 MPa (1 to 8 bar), accommodating diverse applications. It supports multiple voltage inputs such as DC24V, AC110V, and AC220V (50/60Hz), offering flexibility for different power environments.

Designed for longevity, the diaphragm endures over 1 million pulse cycles or up to 5 years of service. Temperature tolerance spans from -25°C to +80°C under standard conditions, and can reach as high as +230°C for high-temperature variants.

The product meets the IP65 protection class, ensuring it is dust-tight and shielded against water jets. Its low power consumption contributes to energy-efficient operation, thereby reducing overall operating costs.
