The Sun Hydraulics NCGBLBN (NCGBLBN) is a needle valve with reverse flow check, designed to provide precise flow regulation in hydraulic systems. This versatile component is fully adjustable, allowing for infinite control from fully closed to the maximum orifice diameter. It features an integral high-capacity check valve that ensures unrestricted flow from port 2 to port 1. While it offers excellent flow control capabilities, it does not include pressure compensation. The NCGBLBN is part of Sun Hydraulics' line of 2-port flow control cartridges, which are interchangeable in terms of flow path and cavity size for a given frame size, although extension dimensions may vary. This needle valve utilizes a balanced adjustment mechanism for ease of use even under high-pressure conditions and incorporates a sharp-edged orifice design to minimize variations due to changes in fluid viscosity. Noteworthy is its compatibility with EPDM seals specifically for systems using phosphate ester fluids; however, exposure to petroleum-based substances can damage these seals. The NCGBLBN model integrates Sun's floating style construction, reducing the risk of internal binding from excessive installation torque or machining variations. It fits into cavity T-18A and belongs to Series 4 with a capacity of 60 gpm (240 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). The valve's leakage rate at 110 SUS (24 cSt) is limited to 10 drops/min (0.7 cc/min). It allows for up to five turns counterclockwise from fully closed to open position and requires specific torque settings during installation: valve hex size is 1-5/8 inches with an installation torque range of 350-375 lbf-ft (474-508 Nm), while the locknut requires torque between 80-90 lbf-in (9-10 Nm). The model weighs approximately 3 pounds (1.35 kg) and includes a Viton seal kit option (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.
- 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.
