The Sun Hydraulics NCGCYBN (NCGCYBN) is a precision-engineered needle valve with a reverse-flow check, designed for regulating hydraulic flow. This component allows for infinite adjustment from fully closed to the maximum orifice diameter, providing flexibility in controlling flow rates. It features an integral high-capacity check valve that ensures unrestricted flow from port 2 to port 1, though it is important to note that the valve is not pressure compensated. The NCGCYBN model is part of the Series 4 range and offers a capacity of 30 gpm (120 L/min) with a maximum operating pressure of 5000 psi (350 bar). The valve incorporates Sun's floating style construction, which minimizes internal binding risks due to installation torque or machining variations. Its sharp-edged orifice design reduces flow variations caused by changes in fluid viscosity, while the balanced adjustment mechanism facilitates easy adjustments even under high-pressure conditions. The needle valve's physical and functional interchangeability with other two-port flow control cartridges ensures compatibility within its frame size, although extension dimensions may differ. Additional specifications include a cavity size of T-18A, a maximum leakage rate of 5 drops/min at 110 SUS (24 cSt), and an adjustment range requiring up to 5.5 counterclockwise turns from fully closed to open. The installation torque ranges between 350 - 375 lbf ft (474 - 508 Nm), with an internal hex size for adjustments at 5/32 in (4 mm). The model weighs approximately 3 lb (1.35 kg) and utilizes Viton seals available under seal kit number 990018006.

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.
