Sanitary Diaphragm Valve is an aseptic valve that can be set to pneumatic head control in addition to handwheel control. It can easily handle the task of opening and closing pipelines. After the reform and opening up, the quality requirements of the pharmaceutical and food industries have been increasingly strengthened, no matter how high the requirements are. This type of valve can also be used in factories such as wineries and beverage factories that require use in a sterile environment.

Sanitary diaphragm valves are mainly used in aseptic process sections of the pharmaceutical, food and beverage industries. These valves can also be used for the treatment and distribution of ultrapure media in the field of and microelectronics, as well as in the field of fine chemicals. Depending on the selected version, it is suitable for ultrapure water (water for injection), ultra-high purity chemicals, intermediates and products of biopharmaceuticals, food processing and chemical industries. The valve can be sterilized and autoclaved, and is also successfully used as a flow control valve in sterile areas.

The operating temperature of the sanitary diaphragm valve is mainly limited by the materials used for the diaphragm and the valve body lining. Under normal circumstances, its operating temperature is about -50℃~175℃. The structure of the diaphragm valve is also very simple, consisting of only three main components: the valve body, the diaphragm and the valve head assembly. The diaphragm valve is also very simple to disassemble and repair, and the maintenance time is short, which improves work efficiency.
Features:
1. The soft rubber stainless steel diaphragm valve can cut off the medium without leakage.
2. The flow path is simple and has a "self-cleaning" effect, which can be used for unclean media.
3. Opening characteristics, but when used as a corrosion-resistant regulating valve, it has to use the front part of the fast opening characteristics, which has a short effective stroke and poor adjustment quality.
4. When closed, the medium force pushes the diaphragm upward, the unbalanced force is large, and a large actuator thrust is required. Therefore, a particularly large, bulky and heavy actuator must be selected, making the valve weight very heavy, which is twice that of a ball valve and 3-4 times that of a full-function light valve.
