Introduction and features of Burkert sanitary diaphragm valves: A sanitary diaphragm valve is a special type of shut-off valve that appeared in the 1920s.

Its opening and closing element is a diaphragm made of soft material, which separates the valve body cavity from the valve cover cavity and the drive components, hence the general name diaphragm valve.

Because it is widely used in sanitary applications and food manufacturing, it is also known as: Burkert sanitary diaphragm valve; Features of Burkert sanitary diaphragm valves: The biggest feature of the most sanitary diaphragm valve is that the diaphragm separates the lower valve body cavity from the upper valve cover.

cavity, so that the valve stem, valve disc, and other parts located above the diaphragm are not corroded by the medium, eliminating the need for a packing seal structure and preventing medium leakage.

Detailed breakdown is as follows:

• The diaphragm is made of soft sealing materials such as rubber or plastic, providing good sealing performance.
• Because the diaphragm is a vulnerable part, it should be replaced periodically depending on the characteristics of the medium.
• Due to the limitations of the diaphragm material, diaphragm valves are suitable for low-pressure and relatively low-temperature applications. Aerosol sampling valves come in various types and can be classified in different ways.
• According to the structural form, they can be divided into six types: roof type, direct flow type, stop type, straight-through type, gate type, and right-angle type;
• the connection form is usually flange connection;
• according to the driving method, they can be divided into three types: manual, electric, and pneumatic, among which pneumatic drive is further divided into normally open, normally closed, and reciprocating types.
• Sanitary diaphragm valves are generally not suitable for use in pipelines with temperatures above 60 degrees Celsius or for conveying organic solvents and strong oxidizing media, nor are they suitable for use in pipelines with high pressure. In line with the needs of social development, sanitary diaphragm valves have been widely used in major food manufacturing industries and are believed to continue to be recognized by the market;
• Burkert diaphragm valve structural principle:
• The aseptic diaphragm valve's sealing structure eliminates sanitary dead corners, which is conducive to automatic media evacuation and more conducive to CIP/SIP processes.
• Due to its structural characteristics, the aseptic diaphragm valve's sealing structure eliminates sanitary dead corners, which is conducive to automatic media evacuation and more conducive to CIP/SIP processes. is recommended to be installed at a 15-30 degree angle (depending on the specific specifications). This facilitates drainage after valve cleaning and prevents liquid stagnation inside the valve.
• The valve body is precision-machined using CNC, ensuring a perfect match between the valve cavity's sealing surface and the diaphragm's curvature, reducing diaphragm friction and extending its service life. The valve cavity surface can be mechanically or electrolytically polished according to customer requirements, achieving a polishing degree of 0.25µm.
• The diaphragm, made of soft, elastic material, will not react sensitively to working media contaminated by fiber clumps, solid particles, catalysts, etc., and generally will not affect the valve's operation or sealing. Different materials can be selected based on the working or sterilization temperature and the chemical properties of the working medium.
• Since different types of valves and materials will be used under different operating conditions, the application of a product must be analyzed before selecting the valve body and diaphragm, especially for applications in the chemical and pharmaceutical fields and chemical reactions caused by high temperatures. The suitability of the materials should be tested through effective chemical data or expert certification to ensure the product's safety and long-term effectiveness.
• The typical method for securing a diaphragm is screw fixing. In contrast to hole fixing, this method distributes the stress across the entire bolt surface, preventing damage to the diaphragm's mechanical connection under vacuum conditions. Burkert Diaphragm Valve Upgrade Notice for the Pharmaceutical Industry! We recently received a notification from Burkert Germany that all Burkert diaphragm valves using Burkert diaphragm pads have been upgraded. The parameters and dimensions are to the previous Burkert diaphragms. Burkert states that they are simply upgraded versions of the original models, with only identical minor differences in the EPDM mixture; Please be aware that ordering Burkert diaphragm pad parts directly from Burkert in Germany has a fast lead time: 1-2 weeks from Germany, and 3-4 weeks by air freight to China after customs clearance. The Burkert manual/pneumatic diaphragm valve series mainly includes models 2030, 2031, 3232, and 3233. Mingbaode Burkert diaphragm valves use imported reinforced silicone rubber diaphragms, and the The valve body undergoes high-speed precision machining and polishing, achieving a surface finish of Ra0.2um. They are sterile, pore-free, and widely used in systems with high sterility requirements, such as those in the biological, pharmaceutical, and electronics industries. Widely used in the beer, beverage, and biopharmaceutical industries, German Burkert diaphragm valves are renowned for their long service life, low maintenance costs, and customizable options to meet specific customer application requirements. This includes Burkert pneumatic diaphragm valves, Burkert manual diaphragm valves, and Burkert electric diaphragm valves, all of which are of superior quality. Their quality and lifespan are significantly better than those of GEMU diaphragm valves from Germany. A high-quality Burkert diaphragm valve can typically last five to six years without failure, requiring only the replacement of the sealing component, the Burkert diaphragm sheet, every few years. Examples of upgraded Burkert diaphragm sheet models: Burkert DN20 Diaphragm DN20 EPDM packed ID Number: 677665 (Discontinued, upgraded model: 00688423);
