The Sun Hydraulics NCFBHCV (NCFBHCV) is a precision-engineered needle valve with a reverse flow check feature, designed for regulating hydraulic flow. This valve is fully adjustable, allowing for precise control from fully closed to the maximum orifice diameter. It features an integral high-capacity check valve that permits unrestricted flow from port 2 to port 1. Notably, this model is not pressure compensated, meaning the fixed orifice size regulates flow in proportion to the square root of the pressure differential across ports 1 and 2. The design incorporates a balanced adjustment mechanism for ease of use even at high pressures and includes a sharp-edged orifice to minimize variations in flow due to changes in viscosity. The NCFBHCV is part of Sun Hydraulics' interchangeable 2-port flow control cartridges, with consistent flow paths and cavity dimensions across similar frame sizes. However, extension dimensions from the mounting surface may differ. The valve's construction minimizes internal binding risks due to excessive installation torque or machining variations. Key specifications include a maximum capacity of 30 gpm (120 L/min), a maximum operating pressure of 5000 psi (350 bar), and minimal leakage rates at specified conditions. The adjustment range spans 5.5 counterclockwise turns from fully closed to open, with specific torque requirements for installation and adjustment components. The valve weighs approximately 1.30 lb (0.60 kg) and uses Viton seal kits for optimal performance.

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.
