Pneumatic L Type KF Angle Valves with Bellow Stainless Steel KF16-50 Vacuum NW Angle Valves SS304 SS36L Angle Valve for Semiconductor
- Overview
- Recommended Products

Angle valves are a device that manually or pneumatic rotates the threadto drive the valve shaft up and down, causing the valve seat to open orclose, thereby connecting or cutting off the airflow in the vacuum system.Valve body designed in 90° right angle(L type) and 45° right angle(Ytype). Connecting Flanges are available in KF, lSO, CF types and Tube endsas well.
They are rated for high-vacuum use and pressure rate from 1X10℃ Pa to1.2x10 Pa, leak rate of 1.3x10℃ Pa L/s.Manually operated angle valves are an excellent solution whenautomation is not required, they are frequently used in roughing andhigh-vacuum forelines and make excellent chamber venting valves.QiMing Angle valves are used in applications ranging from semiconductormanufacturing, plasma physics research, to nuclear accelerators.QiMingoffers all series angle valves suited for vacuum applications such as highvacuum process processes, high vacuum applications in pumpingsystems, semiconductor technology and research systems.
