摘要： A method that simplifies the exchange of data to facilitate delivery of data that relates to operation of a valve assembly to a Web-based user interface over a network. In one embodiment, the method configures an apparatus to receive data about the valve assembly in a first format and to generate an output in a second format, e.g., JavaScript Object Notation (JSON) format. The method may also configure the device with an architecture with multiple layers, wherein the architecture can exchange data in the JSON format between a first layer and a second layer. This architecture is configured to be lightweight as compared to the SOAP/HTTP architecture found in conventional techniques, typically deploying a Representational State Transfer (REST) structure that permits use of JavaScript Object Notation (JSON) format to communicate among the architecture layers and with the web-based user interface.

摘要： A system for detecting degradation of a servo valve; having a controller, a servo valve, a position sensor, and a rate monitor. The controller receives inputs and transmits command data. The servo valve has an actuator and is conductively coupled to the controller to receive command data from the controller and move the actuator in response to the command data. The position sensor operably associated with the servo valve for measuring movement of the actuator and transmits corresponding movement data to the controller. The rate monitor coupled to the controller and position sensor for receiving the command data and the movement data as inputs respectively. The rate monitor processes the inputs to produce a steady state rate error signal. The rate monitor compares the steady state rate error signal to selected operational limits and produces a telemetry output when the operational limits are exceeded.

摘要： A positioner includes a modeling portion that, having input/output characteristics that model an electropneumatic converter, inputs a control signal from a control calculating portion to calculate an estimated value for an input air pressure that is inputted from the electropneumatic converter into a pilot relay, and a shift magnitude calculating portion that calculates a shift magnitude from the equilibrium state of the pilot relay, from the estimated value for the input air pressure, which is calculated by the modeling portion, and the output air pressure that is outputted from the pilot relay. The control calculating portion determines the control signal from an actual opening signal, an opening setting signal, and the shift magnitude from the equilibrium state of the pilot relay, and outputs it to the electropneumatic converter.

摘要： A check valve apparatus includes at least one first test channel including a first pathway extending through a valve body and in communication with a flow path. The pathway is configured to receive a test stick for inserting through the pathway of the test channel to engage a disc such that the disc moves from the open position to the closed position. In further examples, methods for testing a check valve include the step of moving an end of a test stick to engage a downstream face of a disc such that the disc is moved against a bias of a biasing device from the open position to the closed position. The method further includes the step of inspecting an interior portion of the check valve apparatus.
