The Sun Hydraulics NCFBLBN (NCFBLBN) is a needle valve with a reverse flow check, designed to provide fully adjustable orifice regulation of hydraulic fluid flow. It features an integral high-capacity check valve that allows unrestricted flow from port 2 to port 1. This model is not pressure compensated, meaning the flow regulation depends on the pressure differential across ports 1 and 2. The needle valve's sharp-edged orifice design minimizes variations in flow due to changes in fluid viscosity, and its balanced adjustment mechanism ensures easy adjustments even under high pressure. The Sun Hydraulics NCFBLBN supports a maximum operating pressure of 5000 psi (350 bar) and can handle a capacity of up to 30 gpm (120 L/min). It is designed with Sun's floating style construction to prevent internal parts binding due to excessive installation torque or machining variations. The valve's physical specifications include a hex size of 1-1/4 inches (31.8 mm) for installation torque between 150-160 lbf ft (203-217 Nm), and an adjustment screw internal hex size of 5/32 inches (4 mm). The model weighs approximately 1.30 lb (0.60 kg) and includes a Viton seal kit for enhanced durability under various operating conditions. This cartridge is interchangeable with other two-port flow control cartridges within the same series, providing flexibility in hydraulic system design while maintaining consistent performance standards.

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.
