Product Description:
The Mecair DB Series diaphragm repair kits are precisely engineered replacement membranes specifically designed for Mecair VNP/VEM 200 series pulse jet solenoid valves. These valves are extensively utilized in industrial dust collector and baghouse systems. Acting as crucial sealing and actuating components within pulse valves, the diaphragms regulate the valve’s opening and closing, enabling the delivery of compressed air pulses necessary for efficient filter cleaning.
This comprehensive product range accommodates port sizes from ¾ inch up to 3 inches. Each repair kit typically contains the diaphragm or diaphragms, along with the necessary springs, providing everything required for a complete field replacement. This ensures convenient maintenance and optimal performance of the pulse jet valves.
Available in two different material options—NBR (nitrile) and FKM (fluororubber/Viton)—these diaphragms offer outstanding resistance to thermal aging and exhibit broad chemical compatibility. NBR diaphragms are ideal for general-purpose use and can operate effectively within a temperature range of -20°C to +80°C. Meanwhile, FKM versions provide superior chemical resistance and are suitable for high-temperature applications up to +120°C.
The product lineup includes single diaphragm kits such as DB16, DB18, DB112, DB114, DB116, DB120, and DB124. Additionally, combination kits like DB114+DB16, DB116+DB16, and DB120+DB16 are available; these include both main and smaller diaphragms along with springs, designed for multi-diaphragm valves. The DB18M and DB18MV models come packaged either with a plastic seal or in an M-bag.
Each repair kit is meticulously engineered to fit specific Mecair VNP and VEM valve models, including VNP206, VNP208, VNP212, VNP214, VNP216, VNP220, and their equivalents in the VEM series. Recognized worldwide for their reliability, Mecair DB Series diaphragms ensure consistent, high-flow pulse jet cleaning performance while requiring minimal maintenance, making them a trusted choice in the industrial dust collection sector.

Applications:
Dust Collection and Filtration Systems
Pulse jet baghouse dust collectors utilize a reverse pulse cleaning technique to maintain the efficiency of fabric filter bags. This method helps in removing accumulated dust from the bags, ensuring continuous operation and prolonged filter life.
Cartridge filter systems are designed with pleated cartridge filters that require periodic cleaning to sustain optimal performance. These filters effectively capture dust particles and are cleaned regularly to prevent clogging and maintain airflow.
In the cement industry, dust control is critical in various processes including kilns, mills, and material handling operations. Efficient dust collection systems help in reducing emissions and ensuring a safer working environment.
The steel and metallurgy sector faces challenges such as furnace fume extraction and blast furnace dust control. Implementing advanced filtration solutions helps in capturing harmful dust and fumes, thereby improving air quality and complying with environmental regulations.
Power generation plants often deal with fly ash and boiler dust. Effective dust control systems are essential for collecting fly ash and controlling boiler emissions, which are crucial for plant efficiency and environmental compliance.
Chemical processing industries require specialized dust collection for powder handling and process dust. Tailored filtration systems help in managing hazardous dust and maintaining safe production processes.
Mining and quarrying operations generate significant dust during crushing and material handling. Robust dust control systems are necessary to minimize dust emissions and protect workers' health.
Food and grain processing facilities utilize dust extraction systems to maintain cleanliness and hygiene. These systems ensure that dust generated during processing is efficiently removed to comply with health standards.
General industrial filtration involves the maintenance of pulse jet cleaning valves across various sectors. Proper upkeep of these components is vital for the reliable operation of dust collection equipment and overall filtration effectiveness.
