Vacuum Ball Valves have the advantage of being turned completely off to on in one 90 degree rotation of the handle while offering high gas throughput and conductance. Our vacuum ball valves are designed to have a lowleak rate, typically on the order of 1x10-6 Torr. These ball valves have KF16-KF50 vacuum flange for connection to the vacuum system, are manually or pneumatic operated , and made of stainless steel. Primarily used in backing lines on rotary or scroll pumps.

Design and Feature:

* Valve Body : sS304/SS316L
* Gate seal : PTFE packing
* Vacuum Range : 1x10-6 Torr
* Option with ISo nounting pad for pneumatic actuator
