The Sun Hydraulics NCFBLCN (Material Number: NCFBLCN) is a versatile needle valve with a reverse-flow check, designed for precise flow regulation in hydraulic systems. This component features an adjustable orifice that allows for infinite adjustment from fully closed to the maximum orifice diameter, making it ideal for applications requiring variable flow control. It includes an integral high-capacity check valve that permits unrestricted flow from port 2 to port 1, although it is not pressure compensated. The valve's design ensures physical and functional interchangeability with other 2-port flow control cartridges of the same frame size, though cartridge extension dimensions may vary. The needle valve operates by regulating flow in proportion to the square root of the pressure differential across ports 1 and 2 due to its non-compensating nature. It incorporates a balanced adjustment mechanism for easy operation even under high pressures, and its sharp-edged orifice design minimizes flow variations caused by changes in viscosity. The Sun floating style construction helps reduce the risk of internal parts binding due to excessive installation torque or machining variations. Key specifications include a capacity of 30 gpm (120 L/min) with a maximum operating pressure of 5000 psi (350 bar). The valve exhibits minimal leakage at specified conditions and features specific installation and adjustment parameters such as a hex size of 1-1/4 inches and an installation torque range of 150-160 lbf ft. The model weighs approximately 1.30 lb (0.60 kg) and uses Viton seal kits for enhanced durability.

Needle valves with reverse-flow check are fully adjustable orifices used to regulate flow. They are infinitely adjustable from fully closed up to the maximum orifice diameter. An integral high-capacity check valve provides unrestricted flow from port 2 to port 1. They are not pressure compensated.
- 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.
- 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.
