Product Description:
The Mecair DB Series diaphragm repair kits are meticulously crafted replacement membranes specially designed for Mecair VNP/VEM 200 series pulse jet solenoid valves. These valves are commonly employed in industrial dust collector and baghouse systems. Serving as crucial sealing and actuating components, the diaphragms regulate the opening and closing of the valves, enabling the delivery of compressed air pulses that effectively clean filters.
This extensive product range accommodates port sizes from 3/4" up to 3", with each repair kit generally containing the necessary diaphragm(s) and spring(s) to facilitate full field replacement.
Available in NBR (nitrile) and FKM (fluororubber/Viton) materials, these diaphragms provide excellent resistance to thermal aging and a wide spectrum of chemicals. NBR diaphragms are ideal for general-purpose uses, operating efficiently within temperatures ranging from -20°C to +80°C. In contrast, FKM variants offer superior chemical resistance and are suited for high-temperature conditions, operating up to +120°C.
The product line 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, incorporating both main and auxiliary diaphragms along with springs designed for multi-diaphragm valves. Notably, the DB18M and DB18MV models are offered in either plastic-sealed packaging or M-bag packaging options.
Each repair kit is specifically engineered to fit Mecair VNP/VEM valve models including VNP206, VNP208, VNP212, VNP214, VNP216, and VNP220, along with their corresponding VEM versions. Renowned worldwide in industrial dust collection applications, the Mecair DB series diaphragms ensure dependable, high-flow pulse jet cleaning performance while requiring minimal maintenance.

We provide multiple material options to suit different operational environments. Standard NBR materials perform efficiently within a temperature range of -20°C to +80°C, while high-temperature resistant FKM/Viton materials are available for use up to +120°C. This variety guarantees broad media compatibility for diverse industrial needs.
Our complete repair kits come fully equipped with diaphragms and springs required for comprehensive field replacements. These kits simplify maintenance tasks, allowing for quick and effective valve servicing without the need for additional parts.
For applications requiring multi-diaphragm valves, we offer combination kits such as DB114+DB16, DB116+DB16, and DB120+DB16, each including two springs. These kits provide a convenient solution for complex valve assemblies and ensure optimal performance.
The diaphragms feature a fabric-reinforced design, utilizing nylon-reinforced NBR, which offers excellent resistance to thermal aging. This construction enhances durability and extends the service life of the valve components.
Precision-engineered sealing technology is incorporated to guarantee reliable valve operation and minimize air leakage. This attention to detail helps maintain system efficiency and reduces operational costs.
Designed to withstand demanding operating conditions, these valves boast a high cycle life exceeding 1 million pulse cycles, making them ideal for use in rigorous dust collector environments.
The product range covers a variety of port sizes including 3/4", 1", 1-1/2", 2", 2-1/2", and 3", enabling wide application flexibility across different piping and system configurations.
For added convenience, the DB18M and DB18MV models are available in plastic-sealed packaging or M-bag packaging, ensuring product protection and ease of handling.
Maintenance is straightforward with a simple replacement procedure designed to minimize downtime and keep your operations running smoothly.
Manufactured according to strict Mecair OEM specifications, these products guarantee reliable fit and consistent performance, ensuring the quality and dependability you expect.
