VK series ball valves are sturdy isolation devices for the rough and fine vacuum range. A precisely machined ball with a hole through the middle is rotated by means of shaft and lever. When the valve is open, the hole provides unimpeded passage of media over the entire nominal cross section. Ball valves are therefore also used for load locks, e.g., for sample holders, thermocouples or helium supply lines. Wetted parts are stainless steel, FKM and brass (partly hard chromium plated). 25 mm nominal flange width. Leakage rate 1x10-6.
