The Sun Hydraulics NCFBHDV (NCFBHDV) is a precision-engineered needle valve with reverse flow check, designed to provide adjustable flow regulation with an integrated high-capacity check valve for unrestricted reverse flow. This model allows for infinite adjustment from fully closed to the maximum orifice diameter, making it versatile for various hydraulic applications. It is important to note that this valve is not pressure compensated, meaning the fixed orifice size regulates flow in proportion to the square root of the pressure differential across its ports. The NCFBHDV features a balanced adjustment mechanism, ensuring easy adjustments even under high-pressure conditions, and a sharp-edged orifice design that minimizes flow variations due to changes in fluid viscosity. The valve incorporates Sun's floating style construction, which helps prevent internal parts from binding due to excessive installation torque or machining variations. This needle valve fits into a T-16A cavity and operates at a maximum capacity of 30 gpm (120 L/min) with a maximum operating pressure of 5000 psi (350 bar). It exhibits minimal leakage rates of 10 drops/min (0.7 cc/min) at 110 SUS (24 cSt). The NCFBHDV requires specific installation and adjustment torques: installation torque between 150 - 160 lbf ft (203 - 217 Nm), locknut torque between 80 - 90 lbf in (9 - 10 Nm), and features an internal hex size of 5/32 inch for adjustments. Weighing approximately 1.30 lb (0.60 kg), this model is compatible with Viton seal kits and benefits from corrosion resistance through zinc-nickel plating.

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.
