The Sun Hydraulics NCGBKAV (Material Number: NCGBKAV) is a needle valve with a reverse-flow check designed for precise flow regulation in hydraulic systems. This valve features an adjustable orifice that allows for infinite adjustments from fully closed to the maximum orifice diameter, providing users with versatile flow control options. An integral high-capacity check valve ensures unrestricted flow from port 2 to port 1, although it is important to note that this model is not pressure compensated. The NCGBKAV is compatible with all 2-port flow control cartridges of the same size, ensuring physical and functional interchangeability. The valve operates efficiently due to its balanced adjustment mechanism, which facilitates easy adjustments even under high-pressure conditions. Its sharp-edged orifice design minimizes flow variations caused by changes in fluid viscosity. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended, as exposure to petroleum-based fluids can damage these seals. The Sun Hydraulics NCGBKAV incorporates floating style construction to reduce the risk of internal parts binding due to excessive installation torque or machining variations in the cavity/cartridge. It fits into a Cavity T-18A and has a series 4 capacity of up to 60 gpm (240 L/min) at a maximum operating pressure of 5000 psi (350 bar). The valve's hex size is 1-5/8 inches (41.3 mm), requiring an installation torque between 350 and 375 lbf ft (474 - 508 Nm). The adjustment screw requires a 5/32 inch (4 mm) internal hex size tool, while the locknut has a hex size of 9/16 inches (15 mm) and should be torqued between 80 and 90 lbf in (9 - 10 Nm). The model weighs approximately 3.00 lb (1.35 kg), making it robust yet manageable for 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.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- 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.
