PLASMADIAM - Vacuum Components

KF FLANGE SYSTEM ISO-KF small flange components are described in DIN 28403 and ISO 2861 in nominal diameters DN 10 to DN 50. The connections suitable for pressures up to 1.10 -8 mbar. With metal seals, the pressure range can be extended to less than 1.10 -9 mbar. All Plasmadiam components are interchangeable with all assemblies made in complain to above standard; all welded assembly is helium leak checked and can be certified to have a leak rate of less than 1.10 -9 mbar.l.s -1 .

An ISO-KF connection consists of two symmetrical flanges and one O-ring seal, which is positionedand supported with an internal or external centering ring (Figure A). The necessary pressing force for the sealing is created by a clamping ring, which is placed over the conical tightening area and is tightened with a wing screw. This allows for a fast, efficient assembly and disassembly without any tools. The flanges can be aligned around its main axis in any direction.

For mounting a KF flange on a base plate, (Figure B) claw clamps or bulkhead clamps are used as clamping elements. The dimensions of the bores in the base plate can be found in the product description of the claws and bulkhead clamps.
