The Sun Hydraulics NCEBOEN (NCEBOEN) is a versatile needle valve equipped with a reverse-flow check, designed for precise flow regulation in hydraulic systems. This valve allows for infinite adjustability from fully closed to the maximum orifice diameter, making it ideal for applications requiring fine-tuned flow control. It features an integral high-capacity check valve that ensures unrestricted flow from port 2 to port 1. Notably, this model is not pressure compensated, meaning the flow regulation is dependent on the pressure differential across ports 1 and 2. The valve incorporates a balanced adjustment mechanism that facilitates easy adjustments even under high-pressure conditions. The sharp-edged orifice design minimizes variations in flow due to changes in fluid viscosity, enhancing performance consistency. The NCEBOEN model is compatible with EPDM seals, suitable for use with phosphate ester fluids; however, it should not be exposed to petroleum-based fluids as this can damage the seals. The construction of this cartridge follows Sun's floating style design to reduce the risk of internal part binding due to excessive installation torque or machining variations. This model fits into cavity T-5A and belongs to Series 2 with a capacity of 12 gpm (45 L/min). It can operate at a maximum pressure of 5000 psi (350 bar) and has minimal leakage rates. The adjustment range spans five full counterclockwise turns from fully closed to fully open. Installation requires specific torque values for both the valve and locknut components, ensuring secure placement within hydraulic systems. With its robust design and reliable performance characteristics, the NCEBOEN needle valve is well-suited for applications demanding precise flow control and efficient operation within specified hydraulic parameters.
