Product Description:
The Mecair DB Series diaphragm repair kits are expertly crafted replacement membranes specifically designed for the Mecair VNP and VEM 200 series pulse jet solenoid valves. These valves are commonly employed in industrial dust collector and baghouse systems to ensure efficient operation. Acting as vital sealing and actuating components, the diaphragms regulate the opening and closing mechanisms of the valve, enabling the delivery of compressed air pulses essential for effective filter cleaning.
This extensive product range accommodates port sizes ranging from 3/4" to 3". Typically, each kit includes one or more diaphragms along with the necessary springs, providing a complete solution for field replacement and maintenance. This ensures that the valves can be serviced promptly and maintain optimal performance in demanding industrial environments.
Mecair offers these diaphragms in two material options: NBR (nitrile) and FKM (fluororubber, also known as Viton). Both materials exhibit impressive resistance to thermal aging and possess wide-ranging chemical compatibility. NBR diaphragms are ideal for general-purpose applications, with operating temperatures spanning from -20°C up to +80°C. In contrast, the FKM versions are tailored for more challenging conditions, offering superior chemical resistance and handling temperatures 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 contain both main and smaller diaphragms along with springs, designed for multi-diaphragm valve setups. Specific models like DB18M and DB18MV are available with plastic-sealed or M-bag packaging to suit different preferences.
Each repair kit is precisely engineered to match particular Mecair VNP and VEM valve models, including VNP206, VNP208, VNP212, VNP214, VNP216, VNP220, and their VEM counterparts. Renowned for their reliability and performance, Mecair DB series diaphragms are trusted worldwide in industrial dust collection systems, providing consistent, high-flow pulse jet cleaning with minimal maintenance requirements.
Features:
Our product range offers comprehensive coverage of part numbers including DB16, DB18, DB18M, DB112, DB114, DB116, DB120, and DB124, catering to a wide variety of Mecair pulse valves. This extensive selection ensures compatibility across numerous applications.
We provide multiple material options to suit different working environments. Standard diaphragms are made from NBR, suited for temperatures ranging from -20°C to +80°C, while high-temperature applications can benefit from FKM/Viton materials, which tolerate temperatures up to +120°C. These options guarantee broad media compatibility.
Our complete repair kits include all necessary components such as diaphragms and springs, enabling full field replacements with ease. Additionally, combination kits like DB114+DB16, DB116+DB16, and DB120+DB16 come equipped with two springs, designed specifically for multi-diaphragm valves.
The diaphragms feature fabric-reinforced construction, utilizing nylon-reinforced NBR that delivers excellent resistance to thermal aging. Precision engineering of the sealing components ensures reliable valve operation while minimizing air leakage.
Built for durability, these components are designed to withstand over one million pulse cycles, making them ideal for demanding dust collector environments. The size range covers port sizes from 3/4", 1", 1-1/2", 2", 2-1/2" to 3", accommodating a wide variety of installations.
For added convenience, models such as DB18M and DB18MV are available with plastic-sealed packaging or M-bag packaging options. The simple replacement procedures facilitate easy maintenance, reducing downtime significantly.
Adhering to strict OEM quality standards, all products are manufactured precisely according to Mecair specifications, ensuring a reliable fit and optimal performance in all applications.

Applications:
Industrial Dust Collection and Filtration Solutions
Pulse Jet Baghouse Dust Collectors
These systems utilize reverse pulse cleaning technology to maintain the efficiency of fabric filter bags. By periodically reversing the airflow, the dust accumulated on the bags is dislodged, ensuring consistent filtration performance.
Cartridge Filter Systems
Cartridge filters rely on pleated elements that offer a large surface area for dust collection. Cleaning is achieved through specialized methods designed to preserve filter integrity while removing dust accumulations effectively.
Applications in the Cement Industry
The cement sector benefits from robust dust control strategies implemented in various operational points such as kilns, mills, and material handling processes. These measures help in minimizing dust emissions and maintaining regulatory compliance.
Steel and Metallurgy
In steel manufacturing and metallurgical processes, controlling emissions from furnace fumes and blast furnaces is critical. Effective dust extraction systems ensure a safer work environment and reduce environmental impact.
Power Generation
Dust control in power plants involves the collection of fly ash and managing boiler emissions. Reliable filtration systems contribute to improved air quality and efficient plant operation.
Chemical Processing
Within chemical processing industries, handling powders and managing process-generated dust are key challenges. Dust collection systems are designed to handle these materials safely and maintain operational efficiency.
Mining and Quarrying
Mining operations and quarrying activities require comprehensive dust control solutions to manage dust generated during crushing and material handling, protecting both workers and equipment.
