NW flange

NW flange, also known as KF flange or QF flange, is a type of quick connect flange commonly used in low to medium vacuum systems.
characteristic

Good sealing performance: Rubber or metal gaskets are used as sealing materials, such as Viton fluororubber, Buna nitrile rubber, Silicone silicone, etc., which can provide highly reliable sealing performance and withstand high pressure and high vacuum conditions. The applicable vacuum degree can reach 10-8mbar and is suitable for vacuum degrees below 10-6Pa.
Easy installation and disassembly: The structure is simple, and two flanges can be fixed together with clamps to complete the installation. When disassembling, only the clamps need to be unscrewed, without the need for complex tools. It can achieve quick overlap and disassembly, making it easy to frequently replace system configurations or perform cleaning operations in laboratory and industrial environments.Compact and lightweight in size: Common specifications range from DN10 to DN50, suitable for small-diameter pipeline systems. With its small size and light weight, it can save space and costs.

Reusable: Components such as flanges, clamps, and sealing rings can be reused multiple times under normal usage conditions, reducing usage costs.

Diverse materials: Flanges are usually made of 304, 316 stainless steel and other materials, as well as aluminum, carbon steel and other materials to meet different corrosion resistance and strength requirements; Clamps are generally made of aluminum; Sealing rings are available in various materials such as Viton, Buna, Silicone, etc
