R Series Gate Valve
Roughing Pump Isolation for Semiconductor Sub-Fab and General Vacuum Applications
The MKS R Series Gate Valve is optimized for isolation of roughing pumps and roughing lines in both semiconductor and general vacuum applications. The R Series is available with a range of options, including pneumatic and manual actuators, lock out tag out capability, and soft-pump bypass to eliminate turbulence and associated particle generation during pumpdown from atmosphere. The R Series employs an elastomer shaft seal for the actuator seal, which enables high performance in a cost effective, high value package for roughing vacuum applications. The stainless steel version of the R Series Gate valve is available in DN80, DN100, and DN160 sizes.
