Product Overview
The FITOK BOSS-FL8-FNS8-10-I-LH is a precision-engineered needle valve designed for fine flow control and reliable isolation in high-pressure hydraulic, process, and pneumatic systems. Manufactured by FITOK, a globally recognized brand in instrumentation and process components, this valve features a robust stem and seat design that delivers accurate, repeatable throttling and bubble-tight shutoff. Its compact, panel-mountable body is constructed from high-grade stainless steel, making it ideal for demanding industrial environments where corrosion resistance, leak integrity, and precise metering are critical. The valve operates on a manual, multi-turn actuation principle, allowing operators to achieve extremely fine adjustments in flow rate with minimal effort.
