Sanitary Diaphragm Valve is especially suitable for solid and easily contaminated inert media:

The sanitary diaphragm valve is equipped with a flexible diaphragm or a combined diaphragm in the valve body and the valve cover, and its closing part is a compression device connected to the diaphragm. The valve seat can be a weir shape or a pipe wall of a straight-through flow channel. The advantage of the sanitary diaphragm valve is that its operating mechanism is separated from the medium passage, which not only ensures the purity of the working medium, but also prevents the possibility of the medium in the pipeline impacting the working parts of the operating mechanism.

The main advantage of the sanitary diaphragm valve is that its operating mechanism is separated from the medium passage, which not only ensures the purity of the working medium, but also prevents the possibility of the medium in the pipeline impacting the working parts of the operating mechanism. In addition, no separate seal of any form is required at the valve stem unless it is used as a safety facility in controlling harmful media.

In the sanitary diaphragm valve, since the working medium contacts only the diaphragm and the valve body, both of which can be made of a variety of different materials, the valve can ideally control a variety of working media. The sanitary diaphragm valve is particularly suitable for media with chemical corrosiveness or suspended particles. The operating temperature of the diaphragm valve is usually limited by the materials used for the diaphragm and the valve body lining, and its operating temperature range is approximately -50 to 175°C.
The close fit between the valve body and the diaphragm of the sanitary diaphragm valve provides the valve body seal and the valve seat seal, ensuring that the inside of the pipeline and the external environment are completely isolated, so the sanitary diaphragm valve is suitable for aseptic processes. The opening and closing of the sanitary diaphragm valve is achieved by the up and down movement of the valve stem. When the valve stem of the sanitary diaphragm valve is in the upper position, the spherical diaphragm bends upward to form a conductive state. When the valve stem moves from top to bottom, it drives the valve core to bend the diaphragm, forcing the diaphragm to be close to the valve seat area or, closing the path to the pipeline fluid. The sanitary diaphragm valve can be operated manually, pneumatically, or controlled by an intelligent controller. The sanitary diaphragm valve can be remotely operated by a pneumatic head or manually operated by a handle. The sanitary diaphragm valve is very suitable for the control and opening/closing tasks of pipeline fluids. Sanitary diaphragm valves are widely used in sanitary brewing, dairy products, beverages and other food industries as well as in the pharmaceutical field under aseptic conditions.
