The Sun Hydraulics NCGCHEN (NCGCHEN) is a needle valve with a reverse-flow check, designed for precise flow regulation in hydraulic systems. This fully adjustable orifice allows for infinite adjustment from fully closed to the maximum orifice diameter, providing versatile flow control. It features an integral high-capacity check valve that permits unrestricted flow from port 2 to port 1, though it is not pressure compensated. The valve's design ensures physical and functional interchangeability with all 2-port flow control cartridges of the same frame size, albeit with potential variations in cartridge extension dimensions from the mounting surface. This needle valve operates by regulating flow through a fixed orifice size that is proportional to the square root of the pressure differential across ports 1 and 2. It incorporates a balanced adjustment mechanism for easy alterations even under high pressures, while its sharp-edged orifice minimizes flow variations due to changes in fluid viscosity. The floating style construction reduces the risk of internal binding caused by excessive installation torque or machining variations. The NCGCHEN model fits into a Cavity T-18A Series 4 and has a capacity of up to 30 gpm (120 L/min) with a maximum operating pressure of 5000 psi (350 bar). The valve exhibits minimal leakage at maximum conditions and offers precise adjustability over five counterclockwise turns from fully closed to open. Its robust design includes specific installation torque requirements and hex sizes for various components, ensuring reliable performance in demanding applications. Additionally, it supports corrosion-resistant features with optional zinc-nickel plating and Viton seal kits available 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.
