The Sun Hydraulics NCFCKEV (NCFCKEV) is a needle valve with a reverse flow check, designed to provide precise flow regulation in hydraulic systems. This valve features an adjustable orifice that allows users to fine-tune the flow from fully closed to the maximum orifice diameter, ensuring versatility in various applications. It incorporates an integral high-capacity check valve that permits unrestricted flow from port 2 to port 1, although it is important to note that this product is not pressure compensated. The NCFCKEV model is part of Sun's series of 2-port flow control cartridges, which are interchangeable in terms of flow path and cavity size for a given frame size, though extension dimensions may differ slightly. This needle valve utilizes a balanced adjustment mechanism, simplifying adjustments even under high-pressure conditions. The sharp-edged orifice design helps minimize variations in flow due to changes in fluid viscosity. Additionally, the Sun floating style construction reduces the risk of internal binding caused by excessive installation torque or machining variations. Key specifications include a capacity of 15 gpm (60 L/min) and a maximum operating pressure of 5000 psi (350 bar). The valve exhibits minimal leakage at 5 drops/min (0.3 cc/min) at standard fluid viscosity levels. Installation and adjustment details include a hex size of 1-1/4 inches (31.8 mm), with installation torque ranging from 150 to 160 lbf-ft (203 to 217 Nm). The adjustment screw features an internal hex size of 5/32 inches (4 mm), while the locknut has a hex size of 9/16 inches (15 mm) and requires a torque between 80 and 90 lbf-in (9 to 10 Nm). The NCFCKEV model weighs approximately 1.30 lb (0.60 kg) and is compatible with Viton seal kits for optimal performance.

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.
