When it comes to the globe valve, it is different from the ball valve since it is a valve used for regulating flow in a pipeline. It consists of a movable disc-type element and a stationary ring seat that has a spherical body. The internal parts of a typical globe valve are the body, the plug, the bonnet and the stem of the valve. How it works is the plug is connected to the stem of the valve which is operated by screw action using a hand wheel in manual valves and automated globe valves use smooth stems rather than threaded stems and they function based on the actuator assembly.
