The Sun Hydraulics NCGBHCV (NCGBHCV) is a versatile needle valve with reverse-flow check, designed for precise flow regulation in hydraulic systems. This fully adjustable orifice can be finely tuned from fully closed to the maximum orifice diameter, allowing for tailored flow control. It features an integral high-capacity check valve that ensures unrestricted flow from port 2 to port 1, although it is not pressure compensated. Notably, all 2-port flow control cartridges share physical and functional interchangeability, maintaining consistent flow paths and cavity sizes across different frame sizes. However, the extension dimensions from the mounting surface may vary. The valve operates by regulating flow in proportion to the square root of the pressure differential across ports 1 and 2 due to its non-compensating nature. Its balanced adjustment mechanism facilitates easy adjustments even under high pressures, while the sharp-edged orifice design minimizes variations in flow caused by changes in fluid viscosity. Cartridges equipped with EPDM seals are specifically intended for systems utilizing phosphate ester fluids; exposure to petroleum-based fluids could damage these seals. Constructed with Sun's floating style design, this needle valve minimizes the risk of internal component binding due to excessive installation torque or machining variations in cavities and cartridges. The NCGBHCV model fits a Cavity T-18A Series 4 and has a capacity of up to 60 gpm (240 L/min), with a maximum operating pressure of 5000 psi (350 bar). The valve has minimal leakage at standard conditions and offers precise adjustability with up to 5.5 counterclockwise turns from fully closed to fully open positions. It requires specific installation torques for both the valve body and locknut, ensuring secure setup within hydraulic systems.

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.
