The Sun Hydraulics NCECLCN (NCECLCN) is a needle valve with a reverse flow check feature, designed for precise flow regulation. This valve is fully adjustable from completely closed to the maximum orifice diameter, allowing for fine-tuned control over hydraulic flow. It includes an integral high-capacity check valve that provides unrestricted flow from port 2 to port 1, although it is not pressure compensated. The valve's design ensures compatibility across all 2-port flow control cartridges, sharing the same flow path and cavity for a given frame size, though extension dimensions may vary. The NCECLCN features a balanced adjustment mechanism for easy operation even under high pressures, and its sharp-edged orifice design minimizes flow variations due to viscosity changes. This model incorporates Sun's floating style construction to reduce the risk of internal binding caused by excessive installation torque or machining variations. The NCECLCN operates within a T-5A cavity series with a capacity of 3 gpm (11 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). It exhibits minimal leakage at maximum valve leakage rated at 5 drops/min (0.3 cc/min) at 110 SUS (24 cSt). The adjustment allows for up to 5.5 counterclockwise turns from fully closed to fully open. Key dimensions include a valve hex size of 1-1/8 in. (28.6 mm), an installation torque range of 45-50 lbf ft (61-68 Nm), an internal hex size for the adjustment screw of 5/32 in. (4 mm), and a locknut hex size of 9/16 in. (15 mm) with locknut torque between 80-90 lbf in. (9-10 Nm). The model weighs .40 lb (.20 kg) and uses Viton seal kit number 990203006 for cartridge sealing requirements.

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.
