Beschreibung
Zusammenfassung:	A valve for regulating a fluid flow includes a body with an opening at a top. The valve also includes a bonnet arranged within the opening, The valve further includes a coupling mechanism joining the body to the bonnet. The coupling mechanism includes a plurality of body lugs extending radially inward toward a stem axis, each body lug of the plurality of body lugs being separated from an adjacent body lug by a body opening. The coupling mechanism also includes a plurality of bonnet lugs extending radially outward from the stem axis, each bonnet lug of the plurality of bonnet lugs being separated from an adjacent bonnet lug by a bonnet opening. Each bonnet lug is adapted to axially move through a corresponding body opening to transition an axial position of the bonnet relative to the body.
