Product Overview
The PARKER 4V-NLL-BN-SS-V is a precision instrumentation needle valve engineered for fine flow regulation and reliable isolation in high-purity and low-flow process systems. Manufactured by Parker Hannifin, a global leader in motion and control technologies, this valve utilizes a threaded stem and tapered needle tip that seats against a matching orifice to deliver accurate, repeatable throttling and bubble-tight shutoff. Its stainless steel body construction makes it suitable for corrosive media, aggressive environments, and applications requiring clean fluid handling. As a manual process valve, it serves a critical role in instrumentation panels, sampling systems, and hydraulic control circuits where precise metering and dependable isolation are essential.
