The Sun Hydraulics NFBCLCN (NFBCLCN) is a versatile needle valve designed for precise flow regulation in hydraulic systems. This fully adjustable orifice can be tuned from fully closed to the maximum orifice diameter, allowing it to function as both a flow control and shutoff valve. While not pressure compensated, this component is ideal for applications where bidirectional flow control is needed, with a preference for flow from port 1 to 2 for interchangeability. The NFBCLCN features a balanced adjustment mechanism that facilitates easy tuning, even under high-pressure conditions. Its sharp-edged orifice design minimizes variations in flow due to changes in fluid viscosity, ensuring consistent performance across different operating conditions. The valve incorporates Sun's floating style construction, reducing the risk of internal binding caused by installation torque or machining variations. It is built with EPDM seals, making it suitable for use with phosphate ester fluids while being incompatible with petroleum-based products. The cartridge's physical and functional interchangeability allows it to fit seamlessly into existing systems using the same cavity size without altering the flow path. With a capacity of 5 gpm (20 L/min) and a maximum operating pressure of 5000 psi (350 bar), this needle valve offers robust performance. The adjustment mechanism allows up to five counterclockwise turns from fully closed to open, providing fine-tuned control over hydraulic flow rates. Installation requires a torque of 20-25 lbf ft (27-33 Nm), and its compact design includes an internal hex size of 5/32 inches for easy adjustments. Additionally, the locknut hex size is 9/16 inches, requiring a torque of 80-90 lbf in (9-10 Nm). With a lightweight design at just .20 lb (.10 kg), the NFBCLCN model provides efficient and reliable performance in demanding hydraulic applications.

Needle valves are fully adjustable orifices used to regulate flow. They are infinitely adjustable from fully closed up to the maximum orifice diameter. They are not pressure compensated and may be used as flow controls or as shutoff valves.
- All 2-port flow control cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size). However, cartridge extension dimensions from the mounting surface may vary.
- Because needle valves are non-compensating devices, the fixed orifice size will regulate flow through the valve in proportion to the square root of the pressure differential across ports 1 and 2.
- A balanced adjustment mechanism allows for easy adjustment even at high pressures.
- The sharp-edged orifice design minimizes flow variations due to viscosity changes.
- The flow path through this valve is bi-directional. The preferred path is port 1 to 2, to allow interchangeability with other flow controls.
- There is no leakage when the adjustment mechanism is turned to the shut-off position.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
