The Sun Hydraulics NCGBHBN (NCGBHBN) is a needle valve with 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, making it versatile for various flow control applications. It includes a high-capacity check valve that permits unrestricted flow from port 2 to port 1, although it is not pressure compensated. The NCGBHBN is part of Sun Hydraulics' line of 2-port flow control cartridges, which are interchangeable in terms of flow path and cavity size within the same frame size, though extension dimensions may vary. The valve's design incorporates a balanced adjustment mechanism, enabling easy adjustments even under high-pressure conditions. Its sharp-edged orifice minimizes variations in flow due to changes in fluid viscosity. It is compatible with EPDM seals for use with phosphate ester fluids but should not be exposed to petroleum-based fluids as this can damage the seals. The floating style construction helps prevent internal binding from excessive installation torque or machining variations. Specifications include a T-18A cavity series 4 capacity of 60 gpm (240 L/min), a maximum operating pressure of 5000 psi (350 bar), and a maximum valve leakage rate of 10 drops/min at 110 SUS (24 cSt). The adjustment range from fully closed to fully open spans approximately 5.5 counterclockwise turns. Installation requires a torque between 350 and 375 lbf ft (474 and 508 Nm). The hex size for the valve is 1-5/8 inches, with an internal hex size for adjustment screws at 5/32 inches and locknut hex size at 9/16 inches requiring torque between 80 and 90 lbf in (9 and 10 Nm). The model weighs approximately 3 pounds (1.35 kg) and uses Viton seal kits like the cartridge model number 990018006 for maintenance.

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.
