The Sun Hydraulics NCEBLBN (Material Number: NCEBLBN) is a versatile needle valve with reverse flow check, designed to regulate flow with precision. This component is fully adjustable from a closed position to the maximum orifice diameter, allowing for fine-tuned control over hydraulic systems. It features an integral high-capacity check valve that enables unrestricted flow from port 2 to port 1, although it is not pressure compensated. The design ensures compatibility as all two-port flow control cartridges are interchangeable in terms of flow path and cavity size, though extension dimensions may vary. The needle valve operates using a balanced adjustment mechanism, facilitating easy adjustments even under high pressures. Its sharp-edged orifice minimizes variations in flow due to changes in fluid viscosity. The cartridge uses Sun's floating style construction to reduce the risk of internal binding from excessive installation torque or machining discrepancies. It can handle a maximum operating pressure of 5000 psi (350 bar) and has a capacity of 12 gpm (45 L/min). The NCEBLBN model includes EPDM seals suitable for phosphate ester fluids but should not be exposed to petroleum-based substances to prevent damage. Installation requires specific torque settings: the valve hex size is 1-1/8 inches with an installation torque of 45-50 lbf ft (61-68 Nm), while the locknut hex size is 9/16 inches needing a torque of 80-90 lbf in (9-10 Nm). The internal adjustment screw has a hex size of 5/32 inches and allows for five counterclockwise turns from fully closed to fully open. This model weighs approximately .40 lb (.20 kg) and incorporates Viton seal kits for enhanced durability.
