Abstract

System and method for monitoring and controlling one or more valves. The method can include sensing a condition of a valve, transmitting the condition to a sensor server, and transmitting a data stream including the condition to an assessment application. The method can also include generating a predictive model and comparing the condition to the predictive model. The method can further include transmitting a control instruction to at least one of a valve positioner and the sensor server and varying the position of the valve based on the control instruction.
