The Sun Hydraulics NCGCKEV (NCGCKEV) is a precision-engineered needle valve with a reverse flow check, designed to provide fully adjustable flow regulation. This versatile component allows for infinite adjustment from fully closed to the maximum orifice diameter, ensuring precise control over fluid dynamics. Featuring an integral high-capacity check valve, it provides unrestricted flow from port 2 to port 1, though it is not pressure compensated. The needle valve is compatible with all 2-port flow control cartridges of the same frame size, offering interchangeable functionality and flow paths. However, the cartridge extension dimensions may vary from the mounting surface. The NCGCKEV model includes a balanced adjustment mechanism that facilitates easy adjustments even under high pressure conditions. The sharp-edged orifice design effectively minimizes variations in flow due to changes in fluid viscosity. Its Sun floating style construction reduces the risk of internal part binding caused by excessive installation torque or machining variations in cavity-cartridge interfaces. With a capacity of 30 gpm (120 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve is robust and reliable for demanding applications. It features minimal leakage at 5 drops per minute under specified conditions and allows up to 5.5 counterclockwise turns for full adjustment from closed to open positions. The NCGCKEV model requires specific installation torque settings and offers user-friendly adjustments with internal hex sizes detailed for both the adjustment screw and locknut. This product weighs approximately 3 pounds (1.35 kg) and includes a Viton seal kit option for enhanced durability in various environments.

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.
