The Sun Hydraulics NCGBKCN (NCGBKCN) is a high-performance needle valve with an integrated reverse-flow check, designed for precise flow regulation in hydraulic systems. This cartridge-style valve allows for infinite adjustment from fully closed to the maximum orifice diameter, providing users with versatile control over flow rates. It features a high-capacity check valve that ensures unrestricted flow from port 2 to port 1, although it is not pressure compensated. The NCGBKCN model is interchangeable with other 2-port flow control cartridges of the same frame size, maintaining consistent flow paths and cavity dimensions. However, the extension dimensions from the mounting surface may differ. This needle valve operates by regulating flow based on the pressure differential across its ports, using a fixed orifice size. Its balanced adjustment mechanism facilitates easy adjustments even under high pressures, while its sharp-edged orifice design minimizes variations in flow due to viscosity changes. The cartridge is constructed using Sun's floating style to reduce internal binding risks caused by excessive installation torque or machining variations. The NCGBKCN supports systems utilizing phosphate ester fluids when configured with EPDM seals but should avoid exposure to petroleum-based substances as they can damage the seals. It fits into the T-18A cavity series and has a capacity of up to 60 gpm (240 L/min) at a maximum operating pressure of 5000 psi (350 bar). With a maximum leakage rate of 10 drops/min at 110 SUS (24 cSt), it offers reliable performance in demanding applications. The valve's installation requires specific torque settings for optimal performance and longevity. Weighing approximately 3.00 lb (1.35 kg), this model also comes with available seal kits for maintenance needs, ensuring continued operational efficiency in various hydraulic applications.

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.
- 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.
