Product Overview
The PARKER N4881510S28NU is a precision needle valve from Parker Hannifin’s N-series family of flow control and modular hydraulic valves. Operating on a fine-threaded, manually adjustable needle-and-seat metering principle, this valve provides accurate, repeatable throttling and shut-off of hydraulic fluid flow within industrial circuits. By varying the annular clearance between the tapered needle and its seat, the N4881510S28NU enables sensitive, low-flow adjustment for fine speed control of actuators, bleed-off circuits, and pressure gauge isolation lines. Its modular, manifold-mounting design allows direct integration into standardized hydraulic valve stacks, making it a compact and serviceable flow control solution for demanding industrial systems.
