The most prominent feature of the sanitary diaphragm valve is that the diaphragm separates the inner cavity of the lower valve body from the inner cavity of the upper valve cover, so that the valve shaft, valve plate and other parts above the diaphragm are not corroded by the medium, which eliminates the need for a packing and sealing structure and prevents leakage.

What is the working area of the sanitary diaphragm valve?
1. Hygiene diaphragm valve is a diaphragm made of soft seals such as rubber or plastic, which has good sealing performance. Since the membrane is a wearing part, it should be replaced regularly according to the properties of the medium.
2. The sanitary diaphragm valve is limited by the diaphragm material, and the diaphragm valve is suitable for low pressure and relatively low temperature occasions.
3. Sanitary diaphragm valves can be divided into six types according to the structure: house type, DC type, shut-off type, through type, gate type and right angle type; the connection form is usually a flange connection; Depending on the drive method, it can be divided into manual, electric and reciprocating drives.
4. Sanitary diaphragm valves are generally not suitable for use in pipelines with temperatures above 60°C and for conveying organic solvents and highly oxidizing media as well as in pipelines with higher pressures.
The sanitary diaphragm valve is controlled remotely by a drive device or manually operated by a handle. There are three standard drive units: openers, closers and gas-air. It has the advantages of simple structure, beautiful appearance, fast disassembly and assembly, flexible operation, low liquid resistance, safe and reliable use and so on. It is suitable for controlling water, gas, oil and corrosive media in chemical, petroleum, metallurgy, water heating, food, medical and other industries.
The operating temperature of sanitary diaphragm valves is usually limited by the materials used in the diaphragm and valve body lining, and their operating temperature range is approximately -50 to 175 °C. The diaphragm valve has a simple structure and consists of only three main parts: the valve body, the diaphragm and the valve cover assembly. The valve is easy to disassemble and quick to repair, and the replacement of the diaphragm can be carried out on site and in a short time. By separating the actuator mechanism and medium passage, the sanitary diaphragm valve is suitable not only for production in the food and medical and health industries, but also for some difficult and dangerous media. The use of a wider variety of synthetic rubber and engineering plastics as well as a wider range of valve body lining materials make diaphragm valves a widely used application in various areas of modern industry.
