The Sun Hydraulics NCFBYBV (NCFBYBV) is a needle valve with a reverse flow check that serves as a fully adjustable orifice designed for precise flow regulation. This valve can be adjusted infinitely from fully closed to the maximum orifice diameter, allowing for tailored flow control. It features an integral high-capacity check valve that ensures unrestricted flow from port 2 to port 1, although it is important to note that it is not pressure compensated. The NCFBYBV model is part of the 2-port flow control cartridge series, which are interchangeable both physically and functionally within the same frame size, though extension dimensions may vary. The needle valve's non-compensating design regulates flow through a fixed orifice size in proportion to the square root of the pressure differential across ports 1 and 2. This model incorporates a balanced adjustment mechanism for easy adjustments even under high pressure conditions. Its sharp-edged orifice design helps minimize variations in flow due to changes in fluid viscosity. Additionally, Sun's floating style construction reduces the risk of internal parts binding caused by excessive installation torque or machining variations. Key specifications include a cavity size of T-16A Series 3 with a capacity of 30 gpm (120 L/min) and a maximum operating pressure of 5000 psi (350 bar). The valve has minimal leakage, with a maximum leakage rate at 110 SUS (24 cSt) being just 10 drops/minute (0.7 cc/min). The adjustment range spans up to 5.5 counterclockwise turns from fully closed to fully open, and installation requires specific torque settings for both the valve and locknut. The NCFBYBV weighs approximately 1.30 lbs (0.60 kg) and uses Viton seals with an available seal kit number of 990-016-006.

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.
