The Sun Hydraulics NCFCYDV (NCFCYDV) is a needle valve with a reverse flow check, designed to regulate flow through fully adjustable orifices. This component allows for infinite adjustment from fully closed to the maximum orifice diameter, providing flexibility in flow regulation. It features an integral high-capacity check valve that enables unrestricted flow from port 2 to port 1. Although not pressure compensated, the valve's design includes a balanced adjustment mechanism for ease of use even under high pressures. The sharp-edged orifice minimizes flow variations due to viscosity changes, while Sun\u2019s floating style construction reduces the risk of internal parts binding due to excessive installation torque or machining variations. This model fits into a Cavity T-16A Series 3 and has a capacity of 15 gpm (60 L/min), withstanding a maximum operating pressure of 5000 psi (350 bar). The valve leakage at 110 SUS (24 cSt) is minimal, at only 5 drops/min (0.3 cc/min). The NCFCYDV can be adjusted through 5.5 counterclockwise turns from fully closed to fully open. Key dimensions include a valve hex size of 1-1/4 inches (31.8 mm) and an installation torque requirement of 150-160 lbf ft (203-217 Nm). For adjustments, it has an internal hex screw size of 5/32 inches (4 mm), and the locknut requires a torque of 80-90 lbf in (9-10 Nm). Weighing in at approximately 1.30 lb (0.60 kg), this model is compatible with Viton seal kits identified by part number 990016006.
