The Sun Hydraulics NCGCKAV (NCGCKAV) is a needle valve designed with a reverse-flow check, offering fully adjustable orifices for precise flow regulation. This component allows for infinite adjustment from fully closed to the maximum orifice diameter, making it versatile for various applications requiring controlled flow. An integral high-capacity check valve ensures unrestricted flow from port 2 to port 1, although it is important to note that these valves are not pressure compensated. All two-port flow control cartridges are designed to be physically and functionally interchangeable within their frame size, though the extension dimensions might differ. The needle valve's non-compensating nature means that the fixed orifice size regulates flow proportionally to the square root of the pressure differential between ports 1 and 2. The design features a balanced adjustment mechanism, facilitating easy adjustments even at high pressures. The sharp-edged orifice minimizes variations in flow due to changes in viscosity. Additionally, Sun's floating style construction reduces the risk of internal parts binding from excessive installation torque or variations in cavity-cartridge machining. This model fits into a T-18A cavity and is part of Series 4 with a capacity of 30 gpm (120 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). It has minimal leakage at maximum conditions and requires specific torque settings for installation and adjustment. Weighing approximately 3 pounds (1.35 kg), this needle valve includes a Viton seal kit option for enhanced durability.
