Product Overview
The FITOK NF6L-UMB14-9-G is a precision-engineered needle valve from FITOK’s NF series of general process and pneumatic valves. Designed for fine manual flow regulation and reliable isolation in high-pressure hydraulic and pneumatic systems, this valve features a 6 mm (1/4 in) tube outer diameter connection with a 9 mm hex body configuration. The needle valve’s tapered stem and matched seat deliver precise, repeatable throttling characteristics, making it ideal for instrumentation, sampling systems, and analytical panels where accurate flow control is critical. Its robust 316 stainless steel construction ensures compatibility with a wide range of aggressive media and provides long-term leak-tight performance in demanding industrial environments.
