What is a Valve Stem?<\/strong><\/h3>\n

A\u00a0valve stem<\/strong>\u00a0is a critical component in valves, acting as the connecting rod that transfers motion from the actuator (handle, lever, or motor) to the valve disc or plug, controlling fluid flow. It ensures proper sealing and smooth operation in industrial, automotive, and plumbing systems.<\/p>\n
