The Sun Hydraulics NCGCLDN (NCGCLDN) is a needle valve with reverse flow check, designed for precise flow regulation. This valve offers infinite adjustability from fully closed to the maximum orifice diameter, ensuring versatile application in hydraulic systems. It features an integral high-capacity check valve that allows unrestricted flow from port 2 to port 1, though it is not pressure compensated. The valve's design includes a balanced adjustment mechanism for easy operation even under high pressures and a sharp-edged orifice to minimize flow variations due to changes in fluid viscosity. The Sun floating style construction minimizes the risk of internal parts binding during installation or due to machining variations. This model fits into the T-18A cavity and belongs to the Series 4 capacity range, handling up to 30 gpm (120 L/min) with a maximum operating pressure of 5000 psi (350 bar). It has a leakage rate of up to 5 drops/min at 110 SUS (24 cSt). The adjustment can be made over 5.5 counterclockwise turns from fully closed to fully open, with specific torque requirements for installation and adjustments: valve installation torque ranges between 350-375 lbf ft (474-508 Nm), while the locknut requires 80-90 lbf in (9-10 Nm). The hex sizes for adjustment screw and locknut are 5/32 in. and 9/16 in., respectively. Weighing approximately 3 lbs (1.35 kg), this valve is compatible with Viton seal kits, specifically part number 990018006, ensuring reliable sealing performance under various conditions.

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.
