Product Overview
The EATON NV1-8-K-0 (Part Number: 02-172863) is a precision needle valve engineered for accurate flow control and shut-off in industrial hydraulic systems. As a member of Eaton’s NV series, this valve utilizes a fine-threaded needle and seat design to provide infinitely adjustable, micrometer-style flow regulation of hydraulic fluid. The NV1-8-K-0 is a direct-acting, manually operated valve that enables operators to precisely meter flow rates, isolate circuits, or provide controlled deceleration of actuators. Its robust construction and positive sealing characteristics make it an essential component in demanding hydraulic circuits where precise flow management and reliable isolation are critical to system performance and safety.

Engineering Features & Advantages
- Precision Performance: The fine-pitch threaded needle stem allows for extremely sensitive, infinite adjustment of flow rate, enabling accurate speed control of hydraulic actuators and precise metering in complex circuits.
- Positive Shut-Off Capability: When fully seated, the hardened needle and seat design provides a reliable, leak-free seal for circuit isolation, functioning effectively as a manual shut-off valve.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, the valve body and internal components are constructed from high-strength materials resistant to hydraulic fluid degradation and wear.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, ensuring drop-in replacement for Eaton NV1 series valves without modification to existing manifolds or piping.
- Locking Adjustment: Features a locking set screw or knob mechanism to secure the needle position, preventing drift due to vibration or system pressure fluctuations.
Typical Industrial Applications
This Eaton needle valve is widely utilized in heavy industrial scenarios requiring precise flow regulation and isolation. Common applications include plastic injection molding machines for controlling mold closing and injection speeds, metallurgical presses for accurate ram positioning, CNC machine tools for feed rate control of hydraulic slides, and general construction & marine hydraulics where reliable flow metering and circuit isolation are essential for operational safety and process repeatability.
