An example method includes generating a first pressure set point for a valve positioner coupled to an actuator to actuate a valve. The first pressure set point is associated with a partial stroke test of the valve. The example method also includes controlling an output pressure of the positioner towards the first pressure set point to actuate the valve in a stroke direction. The example method further includes determining whether the valve is stuck based on the output pressure."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatus to partial stroke test valves using pressure control","description":"Methods and apparatus to partial stroke test valves using pressure control are disclosed.
