The Sun Hydraulics NCGBYAN (NCGBYAN) is a versatile needle valve with reverse-flow check, designed to provide precise flow regulation in hydraulic systems. This component is fully adjustable, allowing for infinite control from fully closed to the maximum orifice diameter. It features an integral high-capacity check valve that ensures unrestricted flow from port 2 to port 1, although it should be noted that it is not pressure compensated. The NCGBYAN can be interchanged physically and functionally with other 2-port flow control cartridges of the same frame size, albeit with possible variations in cartridge extension dimensions from the mounting surface. The valve's balanced adjustment mechanism facilitates easy adjustments even under high pressure conditions, while its sharp-edged orifice design reduces flow variations due to viscosity changes. This needle valve incorporates a floating style construction that minimizes the risk of internal parts binding due to excessive installation torque or machining variations in the cavity/cartridge interface. It has a capacity of 60 gpm (240 L/min) and can operate at pressures up to 5000 psi (350 bar). The maximum leakage rate is specified at 10 drops/min (0.7 cc/min) at 110 SUS (24 cSt). The adjustment range spans up to 5.5 counterclockwise turns from fully closed to fully open, with specific hex sizes and torque values provided for installation and adjustment components. Weighing in at 3 pounds (1.35 kg), this model can be configured with EPDM seals for compatibility with phosphate ester fluids, though care must be taken as exposure to petroleum-based substances will damage these seals.
