DMF-Z-40S DMF-Z-50S DMF-Z-62S DMF-Z-76S Shanghai Bag Fitting 2″ & 1.5" Inch Diaphragm Pulse Solenoid Valve For Dust Collector System

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. Acting as the compressed air switch in pulse bag dust collector systems, these valves are precisely controlled by output signals from a pulse injection controller. This control allows them to deliver instantaneous and powerful air pulses, ensuring effective cleaning of the filters.

This series offers multiple configurations tailored to meet diverse installation needs. The DMF-Z Series , also known as Right Angle Valves, feature a 90-degree angle between the inlet and outlet ports. They are well-suited for mounting between the air manifold and the blow pipe and come in sizes ranging from 3/4″ to 3″ (models DMF-Z-20 through DMF-Z-76S). On the other hand, the DMF-Y Series , or Submerged Valves, are embedded directly into the air manifold or air tank. These valves provide enhanced flow characteristics with reduced pressure drop, making them ideal for applications with low air pressure. Size options span from 1″ to 5″ (models DMF-Y-25 to DMF-Y-120S).

Additionally, the DMF-ZM Series incorporates the right-angle design of the Z series but includes fixing nuts on both inlet and outlet ports. This feature facilitates easier installation and greater convenience during use. For systems requiring a straightforward airflow path, the DMF-T Series offers straight-through valves with inlet and outlet aligned on the same centerline, suitable especially for air tank pulse dust collectors. Lastly, the DMF-FS Series features valves with flanged connections to ensure secure and leak-proof mounting in demanding applications.

Constructed from die-cast aluminum alloy and finished with a durable coating, these valves are built for longevity and robust performance. The diaphragm materials are selectable, with standard options including NBR and fluororubber (FKM), as well as specialized variants designed for high-temperature conditions. Operating within a pressure range of 0.1 to 0.8 MPa (1 to 8 bar), the valves support various voltage inputs such as DC 24V, AC 110V, and AC 220V. Their diaphragms boast a service life exceeding one million pulse cycles, or up to five years of usage.

Recognized and trusted by industries around the world, the Shanghai Bag Fittings SBFEC DMF Series valves provide reliable, high-flow pulse jets that promote efficient dust removal and extend the lifespan of filter bags. The company holds 18 patents related to baghouse dust collection products and stands as one of China’s most comprehensive manufacturers in the dust collector accessory sector.

Features:

This valve series offers multiple configuration options to suit various installation needs. The designs include right-angle (DMF-Z), submerged (DMF-Y), right-angle with nut (DMF-ZM), straight-through (DMF-T), and flanged (DMF-FS) models.

The right-angle design features a 90° inlet-outlet arrangement, enabling a compact installation between the air manifold and the blow pipe. The DMF-ZM variant incorporates fixing nuts on both ports, facilitating quick, tool-free installation and simplifying maintenance tasks.

In the submerged design, the valve seat is embedded directly into the air manifold. This setup minimizes pressure loss and enhances flow characteristics, making it especially suitable for low-pressure applications.

Featuring inlet and outlet ports aligned on the same centerline, the straight-through design allows smooth and unrestricted airflow, improving operational efficiency.

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

Multiple diaphragm materials are available, including standard NBR and FKM (fluororubber), to support applications requiring high-temperature resistance and chemical durability.

Designed to operate within a wide pressure range of 0.1 to 0.8 MPa (1 to 8 bar), this valve series accommodates various system requirements.

Electrical options include DC24V, AC110V, and AC220V (50/60Hz), providing compatibility with different power supplies.

The diaphragm boasts an exceptionally long service life, exceeding 1 million pulse cycles or up to 5 years of operation.

Temperature tolerance ranges from -25°C to +80°C for standard applications, with a high-temperature option available up to +230°C.

Furthermore, the valve is rated with an IP65 protection class, making it dust-tight and resistant to water jets.

Its low power consumption design contributes to energy-efficient operation and reduced operating costs.
