Stainless steel sanitary flange butterfly valve check valve is a valve that combines the functions of butterfly valve and check valve, mainly used in the fields of non negative pressure water supply equipment and food machinery.
Definition and Structure
Stainless steel sanitary flange butterfly valve check valve is made of stainless steel material (such as 304, 316L, etc.) and is tightly connected to the pipeline system through flange connection. There is a disc-shaped butterfly plate inside, which can rotate around its own axis to achieve the functions of opening, closing, and flow regulation of the valve. The check valve is automatically opened or closed by the medium pressure to prevent the medium from flowing back.
Application scenarios
This type of valve is mainly used in non negative pressure water supply equipment, food machinery, and other occasions. The integrated design makes the equipment more compact and aesthetically pleasing, especially suitable for occasions with high hygiene requirements, such as the food processing and pharmaceutical industries.
Material and Manufacturing Standards
The main materials for stainless steel sanitary flange butterfly valves and check valves are 304 and 316L stainless steel. Manufacturing standards can be based on national standards such as GB, German DIN, American API, or ANSI.
Characteristics and advantages
High strength and corrosion resistance: The valve body is made of high-quality stainless steel casting or forging, which has the characteristics of high strength and corrosion resistance, and can adapt to various harsh working conditions.
Good sealing performance: The valve seat and butterfly plate are tightly matched to ensure good sealing performance.
Flexible flow regulation: The rotation angle of the butterfly plate can vary between 0 ° and 90 °, achieving precise regulation and truncation of the fluid.
Easy installation and maintenance: The flange connection method is easy to install and disassemble, with a simple structure, small size, light weight, and easier maintenance and upkeep.
