ISO ,KF vacuum ball valves are made out of 304 /316L with PTFE seat
The Vacuum ball valves have ultra-high-vacuum tube fitting connections, which are also known as KF, QF, and NW fittings. They’re often used in applications such as vacuum coating and heat treating, leak testing, and analyzing gases. The three-piece bolted body comes apart for inline replacement of internal components.
Body is 316 stainless steel for excellent corrosion resistance. The lockable lever handle can be fixed in place
using a padlock (not included). Valves are full port, so they do not restrict flow.
