Final answer:
The 2-way valve that offers fine metered flow capability is a needle valve, used for precise control of flow in various applications.
Step-by-step explanation:
A 2-way valve that provides fine metered flow capability is the needle valve. Needle valves are designed to give very precise control of flow. They usually have a small, plunger-like mechanism that can be moved in fine increments allowing the valve to accurately control the flow rate, which is particularly useful in situations requiring precise regulation of a fluid or gas. Needle valves are commonly used in calibration applications, where accurate flow must be maintained and adjusted manually.
A 2-way valve that provides fine metered flow capability is called a needle valve. A needle valve is commonly used in engineering applications, such as controlling the flow of gases or liquids with precision.
