The Sun Hydraulics NCGBLDV (NCGBLDV) is a needle valve with a reverse-flow check, designed as a fully adjustable orifice for regulating flow. The valve allows for infinite adjustments from fully closed to the maximum orifice diameter, providing precise control over flow rates. An integral high-capacity check valve ensures unrestricted flow from port 2 to port 1. However, it is important to note that these valves are not pressure-compensated. All two-port flow control cartridges are interchangeable in terms of flow path and cavity for a given frame size, though cartridge extension dimensions may vary. The fixed orifice size regulates flow in proportion to the square root of the pressure differential across ports 1 and 2 due to its non-compensating nature. The balanced adjustment mechanism facilitates easy adjustment even at high pressures, while the sharp-edged orifice design minimizes variations due to viscosity changes. Cartridges configured with EPDM seals are suitable for systems using phosphate ester fluids but can be damaged by petroleum-based fluids and greases. Sun's floating style construction minimizes internal binding risks due to excessive installation torque or machining variations. The NCGBLDV features a T-18A series cavity with a capacity of 60 gpm (240 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). It has an adjustment range of up to 5.5 counterclockwise turns from fully closed to open, with minimal leakage at specified conditions. The valve's hex size is 1-5/8 inches (41.3 mm), requiring an installation torque between 350 - 375 lbf ft (474 - 508 Nm). The adjustment screw has an internal hex size of 5/32 inches (4 mm), while the locknut hex size is 9/16 inches (15 mm) with a torque requirement of 80 - 90 lbf in (9 -10 Nm). The model weighs approximately 3 pounds (1.35 kg) and uses Viton seal kits for sealing 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.
- 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.
