The spindle may have an appendage coupled to a sidewall of the plug, and circumferentially extending about a rotational axis less than 180 angular degrees, such that the spindle appendage is registrable with a valve body outlet to selectively reinforce the plug sidewall and thereby resist blowout of the plug sidewall into or through the valve body outlet.
