Digital Throttle Valve

N/Aype 683 CommunicaTorr Digital Exhaust Throttle Valve is designed for computer integrated applications, where a simple pressure control system is required. The valve integrates all control, communication, and driver circuits via a compact "add-on" electronics module onto a standard MKS Type 253 throttle valve assembly, eliminating the need for a separate pressure control electronics module. The throttle valve can operate in either of two modes, flapper position control or pressure control, via DeviceNet network communications interface.

The valve is compatible with the MKS Type CT27 Digital Baratron capacitance manometer to provide all of the components required for a network pressure-control loop. The valve contains an integral digital valve controller with a second-generation control algorithm that drives the system to set point faster than conventional controllers. The valve will accept standard analog output from traditional Baratron capacitance manometers for closed-loop pressure control and will report pressure back to the host via the DeviceNet link.

Features of the valve include intelligent programming that can monitor and control key setup and run time parameters and provide diagnostic information to automate troubleshooting.
