The Sun Hydraulics NCECYCN (Material Number: NCECYCN) is a needle valve with a reverse flow check, designed for precise flow regulation in hydraulic systems. This valve features an adjustable orifice that can be set from fully closed to the maximum diameter, allowing for tailored flow control. An integral high-capacity check valve ensures unrestricted flow from port 2 to port 1, although it should be noted that this model is not pressure compensated. The valve's design includes a sharp-edged orifice to minimize variations in flow due to changes in fluid viscosity. It also incorporates Sun's floating style construction, which reduces the risk of internal binding caused by installation torque or machining variations. The NCECYCN model fits into a T-5A cavity and supports a series 2 capacity of up to 3 gallons per minute (11 liters per minute) with a maximum operating pressure of 5000 psi (350 bar). The valve has minimal leakage rates at standard conditions, ensuring efficient operation. Its balanced adjustment mechanism allows for easy tuning even under high-pressure conditions, with up to 5.5 counterclockwise turns available from fully closed to fully open positions. Installation requires specific torque settings: the valve hex size is 1-1/8 inches with an installation torque between 45 and 50 lbf-ft, while the locknut hex size is 9/16 inches requiring a torque of 80 to 90 lbf-in. The adjustment screw uses a 5/32 inch internal hex size. The product weighs approximately .40 lbs (0.20 kg) and utilizes Viton seals for durability and reliability in various applications.
