The Sun Hydraulics NCGCLCN (NCGCLCN) is a needle valve with a reverse-flow check designed for precise flow regulation. This valve features an adjustable orifice, allowing it to be finely tuned from fully closed to its maximum diameter. It includes a high-capacity check valve that enables unrestricted flow from port 2 to port 1, though it is not pressure compensated. The product is part of the 2-port flow control cartridges series, which are interchangeable in terms of flow path and cavity size, although extension dimensions may vary. The needle valve's non-compensating nature means that the orifice size regulates flow based on the square root of the pressure differential across ports 1 and 2. Its balanced adjustment mechanism facilitates easy tuning even under high pressures, and the sharp-edged orifice design helps minimize variations due to changes in fluid viscosity. The floating style construction reduces the risk of internal parts binding from excessive installation torque or machining variations. This model fits a Cavity T-18A Series 4 with a capacity of 30 gpm (120 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). The valve has minimal leakage at standard viscosity levels, with specifications indicating just five drops per minute at 110 SUS (24 cSt). It allows for up to five and a half counterclockwise turns from fully closed to open. Installation requires specific torque settings for both the valve and locknut, ensuring secure placement. Weighing in at approximately 3 pounds (1.35 kg), this cartridge also accommodates Viton seal kits for effective sealing solutions.
