The Sun Hydraulics NCGCKEN (NCGCKEN) is a precision-engineered needle valve with reverse flow check, designed to regulate fluid flow with high accuracy. This component features an adjustable orifice that allows for infinite control from fully closed to the maximum orifice diameter. It includes a high-capacity check valve that ensures unrestricted flow from port 2 to port 1, although it is not pressure compensated. The needle valve's design allows for easy adjustment even under high pressure, thanks to its balanced adjustment mechanism. Its sharp-edged orifice minimizes flow variations due to changes in fluid viscosity. The NCGCKEN model incorporates Sun's floating style construction which reduces the risk of internal binding due to excessive installation torque or machining variations. It fits into a Cavity T-18A and belongs to Series 4, offering a capacity of up to 30 gpm (120 L/min) at a maximum operating pressure of 5000 psi (350 bar). The valve has very low leakage rates, with maximum leakage at 110 SUS (24 cSt) being only five drops per minute (0.3 cc/min). Specific dimensions include a valve hex size of 1-5/8 inches (41.3 mm), an internal hex size for the adjustment screw of 5/32 inches (4 mm), and a locknut hex size of 9/16 inches (15 mm). The locknut torque ranges between 80 and 90 lbf-in (9 to 10 Nm), while the installation torque is between 350 and 375 lbf-ft (474 to 508 Nm). The model weighs approximately 3 pounds (1.35 kg) and uses Viton seals as part of its cartridge assembly, ensuring durability and resistance against various hydraulic fluids.
