Product Description:
The Mecair DB Series diaphragm repair kits are meticulously engineered replacement membranes specifically designed for Mecair VNP and VEM 200 series pulse jet solenoid valves. These valves are extensively used in industrial dust collector and baghouse systems to maintain efficient operation. As essential components, the diaphragms serve as the primary sealing and actuating elements within the pulse valves, managing the opening and closing mechanisms that release compressed air pulses necessary for effective filter cleaning.
Covering a wide range of port sizes from 3/4" to 3", each repair kit generally includes the diaphragm or diaphragms along with springs, enabling complete field replacements. This ensures that maintenance and repairs can be performed quickly and effectively, minimizing system downtime.
These diaphragms are available in two different materials: NBR (nitrile) and FKM (fluororubber/Viton). Both materials are selected for their excellent resistance to thermal aging and broad compatibility with various chemicals. NBR versions are ideal for general-purpose applications, with operational temperature tolerances ranging from -20°C to +80°C. On the other hand, FKM diaphragms are designed to withstand higher temperatures up to +120°C and offer superior chemical resistance, making them suited for more demanding industrial environments.
The product lineup includes single diaphragm kits such as DB16, DB18, DB112, DB114, DB116, DB120, and DB124. In addition, combination kits like DB114+DB16, DB116+DB16, and DB120+DB16 provide both main and smaller diaphragms paired with springs, tailored for multi-diaphragm valve configurations. Specific models like DB18M and DB18MV are available in either plastic-sealed or M-bag packaging options.
Each repair kit is precisely engineered to fit particular Mecair valve models, including but not limited to VNP206, VNP208, VNP212, VNP214, VNP216, VNP220, and their respective VEM equivalents. Widely trusted in industrial dust collection systems worldwide, the Mecair DB Series diaphragms ensure reliable and high-flow pulse jet cleaning while requiring minimal maintenance efforts.
Features:
Our product range offers comprehensive part number coverage, including DB16, DB18, DB18M, DB112, DB114, DB116, DB120, and DB124 models. This extensive selection ensures compatibility with a wide variety of Mecair pulse valves, catering to diverse application needs.
Customers can choose from multiple material options to suit different operating environments. The standard NBR material performs reliably within a temperature range of -20°C to +80°C, while the FKM/Viton variant is designed for high-temperature applications, supporting operation up to +120°C. These materials provide broad compatibility with various media.
We provide complete repair kits that include all necessary components such as diaphragms and springs, enabling full field replacements with ease. For more complex multi-diaphragm valves, combination kits are also available, including options like DB114+DB16, DB116+DB16, and DB120+DB16, each featuring two springs to ensure optimal performance.
The diaphragms are constructed using a fabric-reinforced design, specifically nylon-reinforced NBR, which delivers excellent resistance to thermal aging. This enhancement helps maintain durability and longevity even under harsh operating conditions.
Our precision-engineered sealing technology guarantees reliable valve operation with minimal air leakage, ensuring efficient system performance. The valves are designed to withstand over one million pulse cycles, making them suitable for demanding dust collector environments where durability is critical.
Covering a broad size range, these valves are available for port sizes including 3/4", 1", 1-1/2", 2", 2-1/2", and 3", providing flexibility to meet various installation requirements. Additionally, the DB18M and DB18MV models come in plastic-sealed or M-bag packaging options to maintain product integrity.
Maintenance is straightforward with a simple replacement procedure that helps minimize downtime and keep systems running smoothly. Manufactured to exact Mecair specifications, our products deliver OEM quality, ensuring a reliable fit and consistent performance across all applications.

Applications:
Dust Collection and Filtration Systems
Pulse jet baghouse dust collectors utilize reverse pulse cleaning technology to maintain the efficiency of fabric filter bags. This method ensures continuous cleaning by intermittently reversing airflow to remove accumulated dust particles from the filters.
Cartridge filter systems are designed to clean pleated cartridge filters effectively. These systems play a crucial role in trapping and removing dust particles from the air, thereby improving air quality and protecting equipment.
In the cement industry, dust control is essential in various stages such as kilns, mills, and material handling areas. Effective dust management helps to maintain environmental standards and ensures the safety of workers.
The steel and metallurgy sectors rely on dust extraction techniques to control furnace fumes and manage dust generated from blast furnaces. Proper dust control contributes to cleaner operations and reduced environmental impact.
Power generation facilities employ systems to collect fly ash and control boiler dust. These measures are critical to maintaining operational efficiency and complying with environmental regulations.
Chemical processing plants handle powders and process dust through specialized collection systems. This helps to prevent contamination and ensures safe working conditions.
Mining and quarrying industries implement dust control methods during crushing and material handling processes. Effective dust suppression enhances visibility, safety, and equipment longevity.
Food and grain processing operations utilize dust extraction systems to maintain hygiene and product quality. These systems help to control airborne particles that can affect the processing environment.
General industrial filtration involves the upkeep of pulse jet cleaning valves used across various industries. Regular maintenance ensures the reliability and longevity of dust collection systems.
