The Sun Hydraulics NCFBYAV (NCFBYAV) is a needle valve with reverse flow check, designed to provide precise flow regulation through an adjustable orifice. This valve allows for infinite adjustments from fully closed to the maximum orifice diameter, offering versatility in controlling hydraulic flow. It features an integral high-capacity check valve that ensures unrestricted flow from port 2 to port 1, though it is important to note that this model is not pressure compensated. The design incorporates a balanced adjustment mechanism, which facilitates easy adjustments even under high-pressure conditions. Additionally, its sharp-edged orifice design reduces flow variations caused by changes in fluid viscosity. This model is part of the 2-port flow control cartridges series and offers physical and functional interchangeability within a given frame size, although cartridge extension dimensions may vary. The NCFBYAV utilizes Sun's floating style construction, minimizing the risk of internal parts binding due to excessive installation torque or machining variations in the cavity/cartridge interface. The valve operates with a maximum capacity of 30 gpm (120 L/min) and can withstand pressures up to 5000 psi (350 bar). It has a minimal leakage rate of 10 drops per minute at 110 SUS (24 cSt). For installation, the valve requires a torque specification of 150 - 160 lbf ft (203 - 217 Nm), with adjustment screw and locknut sizes specified for precise handling during setup. The product weighs approximately 1.30 lb (0.60 kg) and is compatible with Viton seal kits for maintenance purposes.

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.
