R-Series Vacuum Gate Valve
Overview
The MKS R-Series Vacuum Gate Valve is optimized for isolation of roughing pumps and roughing lines in both semiconductor and general vacuum applications. The R Series gate valve is available with a range of options, including pneumatic and manual actuators, lockout tagout capability, and position indicators. The R Series gate valve employs an elastomer shaft seal in place of a bellows seal, which enables high performance in a cost effective, high value package for roughing vacuum applications.
- DN80, DN100, and DN160 sizes
- Stainless steel or aluminum versions
- Allows roughing pump to stay in operation during foreline maintenance
- High performance heater options
