The Sun Hydraulics NCEBYCN (Material Number: NCEBYCN) is a needle valve with a reverse flow check, designed to be a fully adjustable orifice for precise flow regulation. This valve can be adjusted infinitely from fully closed to the maximum orifice diameter, allowing for versatile flow control applications. It features an integral high-capacity check valve that permits unrestricted flow from port 2 to port 1, although it is not pressure compensated. The design ensures physical and functional interchangeability across all 2-port flow control cartridges, maintaining consistent flow paths and cavity sizes within the same frame size, although extension dimensions may vary. The valve's balanced adjustment mechanism facilitates easy adjustments even under high pressure conditions, while the sharp-edged orifice design reduces flow variations caused by viscosity changes. It incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or variations in cavity-cartridge machining. The NCEBYCN model is suitable for systems using phosphate ester fluids when configured with EPDM seals; however, exposure to petroleum-based substances should be avoided as it can damage the seals. Key specifications include a capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), and minimal leakage rates at standard viscosity levels. The valve requires specific installation torques and hex sizes for adjustment screws and locknuts. With its robust design and versatile application potential, this needle valve is ideal for precise fluid control in a variety of hydraulic systems.
