Abstract
Methods and apparatus to load a valve packing are described. An example load apparatus to load a valve packing includes a guide including a flange and a wall protruding from the flange. The wall defines a cavity to receive a biasing element and a stop movable between a non-active state and an active state. The stop in the non-active state to enable movement of the guide in a first rectilinear direction relative to a longitudinal axis of a packing bore of a fluid valve and the stop in the active state to prevent movement of the guide in the first rectilinear direction. The stop to control an amount of deflection of the biasing element in the first rectilinear direction when the stop is in the active state.
