Viton (body seal), RS232, with +/-15VDC Sensor Power Supply (for Baratron). The MKS T2BA Exhaust Throttle Valve is specifically designed for applications where a simple, yet advanced, pressure control system is desired. The T2BA integrates all control, communication, and driver circuits within a throttle valve assembly, thereby eliminating the need for mounting a separate pressure control electronics module. The unique model-based control algorithm and high-speed operation drives the system to set point quickly with minimum overshoot, and ensures repeatable process recipes without operator involvement. Product Features:Compact pressure control system - valve with integrated on-board controller electronics

Bolted Down Flange (M8 x 1.25), Stainless Steel Body. These MKS R-Series gate valves are optimized for isolation of roughing pumps and roughing lines in both semiconductor and general vacuum applications. These R-Series gate valves are well suited for high vacuum (HV) applications down to 1x10 Torr and have options, including pneumatic and position indicators. 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. This listing is for the ISO-100 bolt down vacuum flange version with pneumatic air actuator including a 24 VDC solenoid valve and dual position indicator switches (normally open).
