The T2BA 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 T2BA is also available in geared versions, providing maximum torque and enabling long-term operation in harsh environments.

T2BA Exhaust Throttle Valves can operate in two modes: flapper positioning or pressure control, either of which can be user-activated through the I/O interface. All of the adjustable setup parameters, run time operation, and diagnostics information is available through the communications interface. EtherCAT T2BA is only compatible with EtherCAT manometers.

The downstream pressure control technique provides wide dynamic range, works with all types of pumps, provides fast response, and is tolerant to most effluent gases. The "intelligent instrument" concept results in valuable system space savings, improved noise immunity, and easy access to time-critical process and calibration information as well as on-board diagnostic functions.
