The DMF-Z-DD series is a normally closed (NC), right-angle, pilot-operated pulse solenoid valve designed for industrial dust collection systems. It adopts a 90° airflow channel and an aerospace-grade cast-aluminum body that is compact, corrosion-resistant, and wear-resistant. This valve's patented snap-ring design allows fast coil replacement without tools and easy maintenance. A precision internal diaphragm mechanism ensures stable operation for up to one million pulse cycles, significantly improving system reliability and cleaning efficiency.
- 90° right-angle structure simplifies pipeline layout and saves installation space
- Aerospace-grade cast-aluminum body offers superior corrosion and wear resistance for harsh industrial conditions
- Customizable sealing materials and diaphragms to support a wide range of temperature operating conditions (e.g., cement-kiln exhaust or low-temperature food-processing)
- NPT standard thread and flange mounting options with a special nut design for easy installation.
- Optional explosion-proof (ATEX-certified) models and anti-vibration mounting components for high-noise or explosion-prone environments
This valve supports high- and low-temperature dust collection systems across industries with heavy dust concentration and high humidity. It is suitable for handling wood dust, abrasive powders, and other fine particulates, especially in:
- Flour milling – low-temperature food processing environments
- Furniture manufacturing – sawdust and fiber extraction systems
- Cement manufacturing – high-temperature cement kiln dust
