Valve material: 304/316/316L

Application
The sanitary aseptic diaphragm valve can be remotely operated either by a pneumatic head or manually operated by a handle. It is highly suitable for the control and on/off tasks of pipeline fluids. It is widely applied in the food industries such as sanitary-grade brewing, dairy products, and beverages, as well as in the pharmaceutical field under aseptic conditions.

Working principle
The tight fit between the valve body and the diaphragm provides valve body sealing and valve seat sealing, ensuring complete isolation between the internal and external environments of the pipeline. Therefore, this valve is suitable for aseptic processes.
The opening and closing of the sanitary aseptic diaphragm valve are achieved by the up and down movement of the valve stem. When the valve stem is in the upper position, the spherical diaphragm bends upward, and the valve forms a conducting state. When the valve stem moves from top to bottom, it drives the valve core, causing the diaphragm to bend and forcing the diaphragm to tightly adhere to the valve seat area or closing the path for the pipeline fluid to flow.
This valve can be operated manually, pneumatically or controlled by an intelligent controller.
