Vacuum stainless steel valves and fittings are mainly for semiconductor, lithium technology,etc. There are 3 main series including KF, ISO and CF series. KF flanges are a sexless design made from 304 stainless, they can be used in a wide range of applications such as roughing and foreline plumbing,small plpe systems, systems need frequent cleaning or modification.
ISO flanges is larger than KF flanges, similar to the KF flanges, they use a centering ring for sealing. ISO flanges are widely used in systems that need frequent cleaning or disassembly.
CF flange is a kind of flange for ultra-high vacuum, purchased metal hard seal, can withstand high temperature barbecue.
Vacuum fittings include clamps, blanks, weld flanges, adapters,elbows, tees, reducers, cross, bellows, flanges.
