The Sun Hydraulics NCFBKDV (NCFBKDV) is a versatile needle valve with a reverse-flow check, designed for precise flow regulation through its fully adjustable orifice. This component allows for infinite adjustment from fully closed to the maximum orifice diameter, making it adaptable to various flow requirements. A high-capacity check valve ensures unrestricted flow from port 2 to port 1, although it is not pressure compensated. All 2-port flow control cartridges are interchangeable in terms of flow path and cavity size, though extension dimensions may vary. The valve's fixed orifice regulates flow proportionally to the square root of the pressure differential across ports 1 and 2 due to its non-compensating nature. It features a balanced adjustment mechanism for easy operation even at high pressures and a sharp-edged orifice design that minimizes flow variations due to viscosity changes. The floating style construction reduces the risk of internal parts binding from excessive torque or machining variations. With a capacity of 30 gpm (120 L/min) and a maximum operating pressure of 5000 psi (350 bar), this model is robust enough for demanding applications. It has minimal leakage at specified conditions and requires specific installation torques for optimal performance. The NCFBKDV model weighs 1.30 lb (0.60 kg) and comes with detailed specifications for installation and adjustment, ensuring precision in hydraulic systems where it is implemented.

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.
