The Sun Hydraulics NCFBKEV (NCFBKEV) is a needle valve with a reverse flow check, designed to provide precise flow regulation. This valve is fully adjustable, allowing for infinite control from fully closed to the maximum orifice diameter. It features an integral high-capacity check valve that enables unrestricted flow from port 2 to port 1, though it is not pressure compensated. The NCFBKEV model belongs to the 2-port flow control cartridge family, which are interchangeable in terms of flow path and cavity for a given frame size, although extension dimensions may vary. The valve's design includes a balanced adjustment mechanism for ease of use even under high pressure conditions and a sharp-edged orifice that minimizes variations due to viscosity changes. Its construction incorporates Sun's floating style to reduce the risk of internal parts binding due to excessive installation torque or machining variations. This particular model fits into a T-16A cavity and is part of the Series 3 with a capacity of 30 gpm (120 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). The maximum valve leakage at 110 SUS (24 cSt) is minimal at 10 drops/min (0.7 cc/min). For adjustments, the valve allows for up to five counterclockwise turns from fully closed to fully open. It requires specific installation torques: the valve hex size is 1-1/4 inches (31.8 mm), and it should be installed with a torque between 150-160 lbf ft (203-217 Nm). The adjustment screw has an internal hex size of 5/32 inches (4 mm), while the locknut has a hex size of 9/16 inches (15 mm) with a torque requirement of 80-90 lbf in (9-10 Nm). The model weighs approximately 1.30 lb (0.60 kg) and uses Viton seal kits coded as 990016006.

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.
