The Sun Hydraulics NCFCLEN (NCFCLEN) is a needle valve with a reverse-flow check, designed as a fully adjustable orifice for regulating flow. This model is infinitely adjustable from fully closed to the maximum orifice diameter, allowing precise control over fluid movement. It features an integral high-capacity check valve that provides unrestricted flow from port 2 to port 1 but is not pressure compensated. The NCFCLEN is part of the 2-port flow control cartridge series, which are physically and functionally interchangeable across similar frame sizes, though extension dimensions may vary. The valve regulates flow in proportion to the square root of the pressure differential across ports due to its non-compensating nature. It includes a balanced adjustment mechanism for easy operation at high pressures and a sharp-edged orifice design that minimizes variations due to viscosity changes. The floating style construction reduces the risk of internal binding from installation torque or machining variations. This model fits into Cavity T-16A and has a capacity of 15 gpm (.28 inch/60 L/min) with a maximum operating pressure of 5000 psi (350 bar). Maximum valve leakage at 110 SUS (24 cSt) is limited to 5 drops/min (.3 cc/min). The adjustment range spans five counterclockwise turns from fully closed to open, with specific hex sizes for various components: valve hex size at 1-1/4 in. (31.8 mm), adjustment screw internal hex size at 5/32 in. (4 mm), and locknut hex size at 9/16 in. (15 mm). Installation torque ranges between 150 - 160 lbf ft (203 - 217 Nm), while locknut torque is specified between 80 - 90 lbf in. (9 -10 Nm). The model weighs approximately 1.30 lb (.60 kg) and uses Viton seal kits for cartridge sealing needs.

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.
