A needle valve, also known as an injection valve, is a type of flow control device that allows precise regulation of fluid flow by adjusting the size of its orifice. It features a tapered stem with a small opening at its tip, which can be gradually opened or closed to control the flow rate. This makes it suitable for applications requiring fine flow control, such as in laboratories and precision machinery.
