The Sun Hydraulics NCGCLBN (NCGCLBN) is a versatile needle valve with a reverse flow check, designed for precise flow regulation. This component features an infinitely adjustable orifice, allowing for regulation from fully closed to the maximum orifice diameter. It incorporates an integral high-capacity check valve that facilitates unrestricted flow from port 2 to port 1. The valve is not pressure compensated, meaning the fixed orifice size regulates flow based on the square root of the pressure differential across ports 1 and 2. The balanced adjustment mechanism ensures ease of operation even under high-pressure conditions, while the sharp-edged orifice design minimizes variations in flow due to changes in fluid viscosity. This needle valve is part of Sun's 2-port flow control cartridges and is interchangeable in terms of cavity and flow path dimensions within a given frame size, though cartridge extension dimensions may vary. Its construction includes Sun's floating style design, which reduces the risk of internal parts binding due to excessive installation torque or machining variances. The NCGCLBN model fits into cavity T-18A and belongs to Series 4 with a capacity of up to 30 gpm (120 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). It has minimal leakage at specified conditions and allows for up to 5 drops per minute. The valve's physical specifications include a hex size of 1-5/8 inches with an installation torque range between 350 - 375 lbf ft (474 - 508 Nm). It features an adjustment screw with an internal hex size of 5/32 inches and a locknut hex size of 9/16 inches, with locknut torque specified between 80 - 90 lbf in (9 -10 Nm). Weighing approximately 3 pounds (1.35 kg), this model is compatible with Viton seal kits, specifically part number: 990018006.

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.
- 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.
