Product Overview
The SUN Hydraulics NCCB LCN is a precision needle valve designed for fine manual flow control within hydraulic circuits. As a member of the Sun Hydraulics family of flow control and modular valves, the NCCB LCN functions as a direct-acting, adjustable needle valve that provides accurate, repeatable throttling of hydraulic fluid across a wide range of flow rates. Its needle-and-seat design allows for sensitive adjustment of flow in both directions, making it an ideal component for meter-in, meter-out, and bypass flow control circuits. The LCN adjustment option denotes a specific manual control configuration, offering tactile, lockable needle positioning for applications requiring stable, tamper-resistant settings. Manufactured to Sun Hydraulics’ exacting tolerances, this valve is engineered for long service life and consistent performance in demanding industrial hydraulic systems.

Engineering Features & Advantages
- Precision Flow Metering: The needle-and-seat geometry delivers sensitive, linear adjustment of flow rate, enabling accurate speed control of actuators and precise circuit tuning.
- Lockable LCN Adjustment: The LCN control option provides a lockable manual adjustment mechanism that maintains the set needle position under vibration and dynamic operating conditions, preventing drift in critical flow settings.
- Bidirectional Throttling: The valve controls flow equally in both directions, offering flexible integration into meter-in, meter-out, and bypass control circuits without additional components.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened needle and seat surfaces for wear resistance and long service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Sun Hydraulics cartridge cavity standards, ensuring drop-in replacement without modification.
Typical Industrial Applications
The SUN Hydraulics NCCB LCN needle valve is widely deployed in heavy industrial hydraulic systems where precise, stable flow control is essential. Typical applications include plastic injection molding machines requiring accurate actuator speed regulation, metallurgical presses and rolling mills where controlled flow governs ram descent and pressure build-up, construction and marine hydraulic systems needing reliable manual flow adjustment in remote or vibration-prone environments
