Description
The Nor East Controls 30041035-854 Upper Stem Wiper is a sealing and wiping component to control moisture and particulate entry around valve stem assemblies. It maintains a close interface with the moving stem, reducing contamination around internal control parts and supporting smooth mechanical movement. Installed in valve or actuator assemblies, it is positioned at the upper stem section where motion occurs during regulation of flow. Within HVAC systems, it is used in control valve configurations found in air handling and hydronic heating equipment, contributing to consistent operation of modulation components.
