Beschreibung
Zusammenfassung:	A stem connector assembly includes a connector body formed from a single piece of metal, and having a frame portion and a valve stem passageway extending through the frame portion. In one aspect, the connector body also includes an actuator stem passageway extending through the frame portion, and has a locking unit. The locking unit couples an actuator stem and a valve stem to the connector body. In operation, the stem connector assembly provides for unified movement of the actuator stem and valve stem, permits some misalignment between the two, thus reducing wear of the associated rod and stem components. The stem connector assembly further includes at least one mounting assembly, such as among others at least one NAMUR standard mounting assembly, to facilitate ready mounting of component elements associated with a stem connector assembly, such as a positioner, for example. The connector assembly also includes a size adjustment system, to accommodate a wide variety of valve and/or actuator stem sizes without exchanging for a connector body of another size.
