A diaphragm valve is a type of compression device where a flexible diaphragm or a combined diaphragm is installed inside the valve body and bonnet, with the closing element connected to the diaphragm. The valve seat can be either weir-shaped or the wall of a straight-through flow channel. The advantage of a diaphragm valve is that its operating mechanism is separated from the medium passage, ensuring the purity of the working medium and preventing the possibility of the medium in the pipeline impacting the operating components. Additionally, no separate sealing is required at the valve stem unless used as a safety measure when controlling hazardous media. In diaphragm valves, since only the diaphragm and the valve body come into contact with the working medium, both can be made from a variety of materials, making this valve ideal for controlling various working media, especially those with chemical corrosiveness or suspended particles. The working temperature of diaphragm valves is generally limited by the materials used for the diaphragm and the valve body lining, with a typical operating temperature range of approximately -50°C to 175°C. Diaphragm valves have a simple structure, consisting of only three main components: the valve body, the diaphragm, and the valve head assembly. The valve is easy to disassemble and maintain quickly, and diaphragm replacement can be completed on-site in a short time.
