Detailed introduction:
The all-stainless steel flanged butterfly valve is a common type of valve; here's an introduction to it:
Structural Components: Primarily composed of a stainless steel valve body, butterfly disc, stem, sealing ring, and flanges, among other parts, and can be paired with electric, pneumatic, or other types of actuators.
How it works: The actuator drives the valve stem, causing the butterfly disc to rotate 0–90°, thereby opening, closing, or regulating the flow of the medium.
Performance parameters: Nominal diameters typically range from DN40 to DN4000, with nominal pressures spanning PN10 to PN25. The applicable temperature range varies depending on the sealing material—e.g., rubber seals generally operate between 0°C and 80°C, while metal seals can withstand temperatures up to 425°C.
Product features: It boasts excellent resistance to corrosion, wear, and high temperatures and pressures. Featuring a three-dimensional eccentric elastic design or a multi-layered hard-sealing structure, it delivers reliable sealing performance, offers bidirectional sealing, and is easy to install—unaffected by the flow direction of the medium or its spatial orientation.
Application areas: Widely used in industries such as food, chemical processing, water treatment, and power generation, suitable for a variety of media including water, air, oil, acids, and alkalis.
