The Sun Hydraulics NCFCLCN (NCFCLCN) is a precision-engineered needle valve with a reverse flow check, designed for regulating flow in hydraulic systems. This valve is fully adjustable, offering infinite control from a closed position to its maximum orifice diameter, allowing for precise flow management. It features an integral high-capacity check valve that permits unrestricted flow from port 2 to port 1, although it is not pressure compensated. The NCFCLCN model is part of the 2-port flow control cartridges that are interchangeable in terms of flow path and cavity size for a given frame size. This needle valve operates by regulating flow through the fixed orifice proportional to the square root of the pressure differential across ports 1 and 2. Its balanced adjustment mechanism ensures ease of use even at high pressures, and its sharp-edged orifice design minimizes variations caused by changes in fluid viscosity. The NCFCLCN incorporates Sun's floating style construction to reduce the risk of internal parts binding due to excessive installation torque or machining variations. Key specifications include a capacity of 15 gpm (60 L/min), a maximum operating pressure of 5000 psi (350 bar), and minimal leakage at 110 SUS (24 cSt) with only 5 drops/minute. The valve has an adjustment range of up to 5.5 counterclockwise turns from fully closed to fully open, with specific torque requirements for installation and adjustment components. Weighing in at 1.30 lb (0.60 kg), this model also includes detailed dimensions for hex sizes and locknut torque settings, ensuring precise installation and maintenance within hydraulic systems requiring reliable flow control solutions.
