The Sun Hydraulics NCECYAN (Material Number: NCECYAN) is a needle valve with a reverse flow check, designed as a fully adjustable orifice to regulate flow. This valve is capable of infinite adjustment from fully closed to the maximum orifice diameter and features an integral high-capacity check valve that allows unrestricted flow from port 2 to port 1. It is important to note that this model is not pressure compensated. All two-port flow control cartridges, including this one, are physically and functionally interchangeable, sharing the same flow path and cavity for a given frame size, although cartridge extension dimensions might vary from the mounting surface. The NCECYAN model uses a balanced adjustment mechanism, ensuring easy adjustments even under high-pressure conditions. Its sharp-edged orifice design minimizes variations in flow due to changes in viscosity. The valve incorporates Sun's floating style construction, which reduces the likelihood of internal parts binding due to excessive installation torque or cavity/cartridge machining variations. Specifications for this model include a T-5A cavity series with a capacity of 3 gpm (11 L/min) and a maximum operating pressure of 5000 psi (350 bar). The maximum valve leakage at 110 SUS (24 cSt) is limited to 5 drops per minute (0.3 cc/min). Adjustment from fully closed to fully open requires approximately 5.5 counterclockwise turns. The valve hex size measures 1-1/8 inches (28.6 mm), with an installation torque ranging between 45 - 50 lbf-ft (61 - 68 Nm). The adjustment screw has an internal hex size of 5/32 inches (4 mm), while the locknut hex size is 9/16 inches (15 mm), requiring a torque between 80 - 90 lbf-in (9 - 10 Nm). This model weighs approximately .40 lb (.20 kg) and utilizes Viton seal kits for optimal performance.
