What is the difference screw down non return valve and globe valve?

A screw-down non-return valve, also known as a check valve, prevents backflow in a piping system by allowing fluid to flow in only one direction, using a spring or gravity to close when flow reverses. In contrast, a globe valve is designed for controlling flow and pressure within a system; it features a spherical body and a movable disk that can be adjusted to open or close the flow. While the screw-down non-return valve focuses on preventing reverse flow, the globe valve is primarily used for regulating flow rates.
