Product Overview
The Danfoss NV1-10-K-0 (part number 565590) is a precision-engineered cartridge-style needle valve designed for fine manual flow control within hydraulic circuits. As a member of Danfoss’s NV series of modular cartridge valves, this unit functions as a variable restrictor, allowing operators to precisely meter and throttle hydraulic fluid flow in a compact, screw-in cartridge format. The needle valve operates on a simple yet highly effective principle: a tapered needle is threaded into a matching seat, and axial adjustment of the needle varies the annular orifice area, thereby controlling flow rate with high resolution. This cartridge design enables direct integration into custom manifold blocks and integrated hydraulic circuits, eliminating the need for external piping and reducing potential leak points. The NV1-10-K-0 is ideally suited for industrial systems requiring accurate, repeatable flow adjustment, such as actuator speed control, bleed-off circuits, and proportional flow regulation in demanding hydraulic power units.
