The Sun Hydraulics NCECLDN (NCECLDN) is a needle valve with a reverse flow check, designed to regulate hydraulic flow with precision. This valve offers fully adjustable orifices that allow for infinite adjustment from fully closed to the maximum orifice diameter, making it versatile for various applications. An integral high-capacity check valve ensures unrestricted flow from port 2 to port 1, though it is important to note that the valve is not pressure compensated. The NCECLDN is compatible with all 2-port flow control cartridges in terms of flow path and cavity size, although cartridge extension dimensions may vary. This needle valve features a balanced adjustment mechanism for easy operation even under high pressures and employs a sharp-edged orifice design to minimize flow variations due to changes in fluid viscosity. The Sun floating style construction reduces the risk of internal parts binding due to excessive installation torque or machining variations. The NCECLDN fits into a T-5A cavity and has a series capacity of 3 gpm (11 L/min) with a maximum operating pressure of 5000 psi (350 bar). Maximum leakage at 110 SUS (24 cSt) is limited to 5 drops/min (0.3 cc/min). Additional specifications include an adjustment range of up to 5.5 counterclockwise turns from fully closed to fully open, a valve hex size of 1-1/8 inches (28.6 mm), and an installation torque requirement of 45-50 lbf ft (61-68 Nm). The adjustment screw features an internal hex size of 5/32 inches (4 mm), while the locknut requires a hex size of 9/16 inches (15 mm) and torque between 80-90 lbf in (9-10 Nm). The model weighs approximately 0.40 lb (0.20 kg), and it utilizes Viton seal kits for reliable 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.
