The Sun Hydraulics NCFCHDN (Material Number: NCFCHDN) is a needle valve with a reverse flow check, designed for precise flow regulation in hydraulic systems. This valve features an infinitely adjustable orifice, allowing for flow adjustment from fully closed to the maximum orifice diameter. It includes an integral high-capacity check valve that ensures unrestricted flow from port 2 to port 1. Notably, the NCFCHDN is not pressure compensated, meaning the flow regulation depends on the pressure differential across its ports. The valve's balanced adjustment mechanism facilitates easy adjustments even under high pressures, while its sharp-edged orifice design reduces flow variations due to viscosity changes. The Sun floating style construction minimizes internal binding risks caused by excessive installation torque or machining variations. This model is compatible with Cavity T-16A and offers a series 3 capacity of up to 15 gpm (60 L/min) with a maximum operating pressure of 5000 psi (350 bar). The valve exhibits minimal leakage at specified conditions, with a maximum leakage of 5 drops/min (0.3 cc/min). For installation, it requires a torque of 150-160 lbf ft (203-217 Nm) and features an adjustment screw internal hex size of 5/32 in. (4 mm). The locknut has a hex size of 9/16 in. (15 mm) and needs to be torqued between 80-90 lbf in. (9-10 Nm). Weighing in at 1.30 lb (0.60 kg), this valve is constructed for durability and reliability in demanding environments, making it ideal for applications requiring precise flow control without pressure compensation adjustments.

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.
