Abstract: Apparatus and methods to characterize fluid valves are disclosed. An example apparatus includes a fluid valve having a valve seat and a flow control member to sealingly engage the valve seat. The apparatus includes a sensor to detect a change in position of the flow control member. The apparatus includes a processor to determine at least one of a seating point or a breakout point corresponding to the flow control member based on the change in position.

Abstract: Position sensor mounts for mounting one or more position sensors to one or more various fluid control valves and/or actuators for such valves. One such position sensor mount includes a base, a toggle clamp fixedly attached to the base, and an engagement assembly. The base has a mount for coupling to a position sensor and a first clamp jaw. The toggle clamp has a second clamp jaw that opposes the first clamp jaw. The toggle clamp automatically adjusts to provide a fixed clamping force at different distances between the first clamp jaw and the second clamp jaw. The engagment assembly is carried by the second jaw and includes at least a first clamp pad having a distal end that directly faces the first clamp jaw and swivels relative to the second clamp jaw.
