The Sun Hydraulics NCFBYDV (NCFBYDV) is a needle valve with a reverse-flow check, designed for precise flow regulation in hydraulic systems. This valve is fully adjustable, allowing for infinite control from a closed position to the maximum orifice diameter. It features an integral high-capacity check valve that facilitates unrestricted flow from port 2 to port 1. Notably, this model is not pressure compensated, meaning the flow regulation is proportional to the square root of the pressure differential across its ports. The NCFBYDV model incorporates a balanced adjustment mechanism, ensuring easy adjustment even under high-pressure conditions. Its sharp-edged orifice design minimizes variations in flow due to changes in fluid viscosity. This needle valve utilizes Sun's floating style construction, which reduces the risk of internal parts binding from excessive installation torque or machining variations in the cavity-cartridge interface. The cartridge is compatible with cavity T-16A and offers a capacity of 30 gpm (120 L/min) with a maximum operating pressure of 5000 psi (350 bar). Leakage at 110 SUS (24 cSt) is minimal, capped at 10 drops per minute (0.7 cc/min). The adjustment range spans 5.5 counterclockwise turns from fully closed to fully open. Physical specifications include a valve hex size of 1-1/4 inches (31.8 mm), an installation torque requirement of 150-160 lbf ft (203-217 Nm), and an internal hex size for adjustment screws of 5/32 inches (4 mm). The locknut has a hex size of 9/16 inches (15 mm) and requires a torque of 80-90 lbf in (9-10 Nm). Weighing approximately 1.30 lb (0.60 kg), this model also supports Viton seal kits for enhanced durability and performance in various applications.

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.
