The Sun Hydraulics NCFCLAN (NCFCLAN) is a needle valve with a reverse flow check, designed to provide precise flow regulation. This valve allows for full adjustability from closed to the maximum orifice diameter and features an integral high-capacity check valve that enables unrestricted flow from port 2 to port 1. It is important to note that this valve is not pressure compensated, which means the orifice size will regulate flow in proportion to the square root of the pressure differential across ports 1 and 2. The NCFCLAN model incorporates a balanced adjustment mechanism, ensuring ease of adjustment even under high pressures. Its sharp-edged orifice design minimizes flow variations due to changes in viscosity. This model is compatible with all 2-port flow control cartridges, maintaining the same flow path and cavity for a given frame size, although cartridge extension dimensions may vary. The Sun floating style construction minimizes internal part binding due to excessive installation torque or cavity-cartridge machining variations. The NCFCLAN has a maximum operating pressure of 5000 psi (350 bar) and can handle a capacity of up to 15 gpm (60 L/min). It features a cavity type T-16A Series 3 with a maximum valve leakage at 110 SUS (24 cSt) of five drops per minute (0.3 cc/min). The valve's adjustment mechanism allows for up to five counterclockwise turns from fully closed to fully open, and it requires specific torques for installation and locknut adjustments: 150-160 lbf ft (203-217 Nm) for installation torque and 80-90 lbf in (9-10 Nm) for locknut torque. The NCFCLAN model weighs approximately 1.30 lb (0.60 kg) and uses Viton seal kits, specifically part number 990016006, ensuring durability and reliability in various applications.
