Sanitary pneumatic straight-through ball valve

Product Description
Application
This series of ball valves is a hygienic type designed for material transfer control. It is widely used in the food and beverage processing industries, as well as in the pharmaceutical and chemical industries.
Standard Design
We offer a full range of valves compliant with various standards, including DIN, 3A, SMS, ISO/IDF, BS/RJT, and ASME/BPE standards.
The typical components of a ball valve include a handle, a spherical body with a through-flow bore, a valve body, a valve stem, and a stem seal.
The existing series of ball valves includes welded ball valves, clamp-type ball valves, threaded ball valves, and other types.
Working Principle
By rotating the handle through 90°, the precisely manufactured ball with a through-bore is rotated 90° as well, thereby opening or closing the valve to control the flow of the medium.
