An instrumentation-style flow control valve, commonly referred to as a needle valve, is a precision instrument designed to regulate the flow of fluids within a system. Featuring tube or NPT connections, these valves enable controlled flow in both directions. Their needle-like structure allows for precise adjustment, making them ideal for applications requiring metered flow rates. With their versatility and reliability, instrumentation needle valves play a crucial role in various industries, including oil and gas, chemical processing, and manufacturing.
