Category: In-Line Valve Aluminum

Aluminum KF Valves fulfil the leak tightness demands for high vacuum applications. To achieve this leak tightness, Novotek uses bellow sealed valves. The valve housing is made of a solid aluminum profile.

A laser welded bellow made of Stainless Steel 1.4541, with valve plate and seal, guarantees a high vacuum. These valves can be used as high vacuum valve, isolation valve or venting valve. Service life is at 300.000 cycles, bakeout at 140°C.
