The T2B EtherCAT® Exhaust Throttle Valve is specifically designed for applications where a simple, yet advanced, pressure control system is desired. The T2B 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 modelbased control algorithm and high-speed operation drives the system to set point quickly with minimum overshoot, and ensures repeatable process recipes without operator involvement.
T2B Downstream Pressure Controllers are available with the following options.

The T2B utilizes a direct drive high-speed stepper motor. The valve driver provides high resolution pressure control. The optional, high torque direct drive motor provides extended uptime and reduces preventative maintenance cycles — a great advantage in demanding processes where just one hour of downtime can cost thousands of dollars. The T2B is also available in geared versions, providing maximum torque and enabling long-term operation in harsh environments. An encoder-based position feedback system is provided for diagnostic purposes.
