Description
The Honeywell 0901116A Stem Button is a steel valve interface part that transfers actuator motion to the internal stem of compatible globe spouts. It is used in hydronic heating and chilled water control elements of HVAC systems, where it ensures accurate linkage between the actuator and valve stem for flow regulation. The component fits into designated valve bodies and maintains regular mechanical contact during opening and closing movements. Housed in the valve stem path, it provides stable alignment for accurate modulation of fluid flow through the system during testing or power-loss scenarios.
