The Sun Hydraulics NCGBHBV (NCGBHBV) is a needle valve with a reverse flow check, designed for precise flow regulation in hydraulic systems. This versatile component serves as a fully adjustable orifice, allowing users to control flow 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, though it is not pressure compensated. The NCGBHBV is compatible with all 2-port flow control cartridges of the same frame size, offering functional interchangeability despite varying extension dimensions. Its balanced adjustment mechanism facilitates easy adjustments even at high pressures, while the sharp-edged orifice design minimizes variations due to changes in fluid viscosity. The cartridge is designed for use in systems with phosphate ester fluids when configured with EPDM seals but should not be exposed to petroleum-based fluids as they will damage the seals. It incorporates Sun's floating style construction, reducing the risk of internal parts binding due to excessive installation torque or machining variations. This model fits into cavity T-18A and is part of Series 4, providing a capacity of up to 60 gpm (240 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). The valve exhibits minimal leakage at specified conditions and allows for up to 5.5 counterclockwise turns from fully closed to fully open. The NCGBHBV has specific installation requirements including a valve hex size of 1-5/8 inches and requires an installation torque between 350 and 375 lbf ft. The adjustment screw has an internal hex size of 5/32 inches, while the locknut requires a hex size of 9/16 inches and torque between 80 and 90 lbf in. The model weighs approximately 3 pounds (1.35 kg) and uses Viton seal kits identified by part number 990018006 for maintenance or replacement needs.

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.
