Systems and Methods for Data Acquisition from Valve Assemblies

A valve assembly comprising:

• a valve that allows liquid to flow through a flow bore when the valve is open;
• a cavity that is configured to surround the valve;
• a valve sensor that is configured to measure a first pressure of the valve related to the liquid flowing through the valve;
• a cavity sensor that is configured to measure a second pressure within the cavity;
• and
• a control system that is configured to analyze the first pressure readings and the second pressure readings while the liquid is flowing through the flow bore to compare changes in the first pressure readings and changes in the second pressure readings.

A valve assembly for use in frac operations to deliver fluid to a well site comprising:

• a valve that allows liquid to flow through a flow bore when the valve is open;
• a hydraulic cylinder that is configured to control the valve with a component that is configured to open and close the valve;
• a valve sensor that is configured to measure a first pressure of the valve related to the liquid flowing through the valve;
• a hydraulic cylinder pressure sensor that is configured to measure a second pressure within the hydraulic cylinder;
• a hydraulic cylinder load sensor that is configured to measure a first load on the component;
• and
• a control system that is configured to analyze the first pressure readings, the second pressure readings, and the first load readings while the hydraulic cylinder is in operation,
• wherein the analysis includes comparing changes in the first pressure readings, and the second pressure readings, and changes in the first load readings.
