Abstract
A system for converting operation of a valve between an unbalanced operation mode and a balanced operation mode includes a housing adapted to couple to a valve body. The system also includes a lower stem, including lugs, the lugs having a lug diameter that is larger than an adjacent lower stem diameter. The system further includes a valve member nut coupled to a valve member, the valve member nut having an opening to receive the lower stem, and pins extending into the opening, the pins forming a reduced diameter portion of the opening. In the system, the lower stem couples to the valve member, via the valve member nut, when the lugs are axially aligned with the reduced diameter portion and the lower stem decouples from the valve member when the lugs are axially misaligned with the reduced diameter portion.
