The Sun Hydraulics NCFCHDV (NCFCHDV) is a needle valve with a reverse-flow check, designed to provide fully adjustable flow regulation. It features an integral high-capacity check valve that allows unrestricted flow from port 2 to port 1, although it is not pressure compensated. This product is part of the 2-port flow control cartridge series, which are physically and functionally interchangeable within the same frame size. The NCFCHDV offers easy adjustment even at high pressures due to its balanced adjustment mechanism. Its sharp-edged orifice design helps minimize flow variations caused by changes in viscosity. The floating style construction reduces the risk of internal parts binding due to excessive installation torque or machining variations. This needle valve has a cavity specification of T-16A and belongs to Series 3 with a capacity of 15 gpm (60 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), and it has a maximum valve leakage rate of 5 drops/minute at 110 SUS (24 cSt). The adjustment range allows for up to 5.5 counterclockwise turns from fully closed to fully open positions. Key dimensions include a valve hex size of 1-1/4 inches (31.8 mm) and an installation torque requirement of 150\u2013160 lbf ft (203\u2013217 Nm). Additionally, the internal hex size for the adjustment screw is 5/32 inches (4 mm), while the locknut hex size is 9/16 inches (15 mm) with a torque specification of 80\u201390 lbf in (9\u201310 Nm). The model weighs approximately 1.30 lb (0.60 kg) and uses Viton seal kits under part number 990-016-006.
