The Sun Hydraulics NCEBOBV (Material Number: NCEBOBV) is a needle valve with a reverse flow check, designed to provide precise flow control in hydraulic systems. This component features an adjustable orifice that allows for infinite regulation from fully closed to the maximum orifice diameter, ensuring flexibility in various applications. It incorporates an integral high-capacity check valve that permits unrestricted flow from port 2 to port 1, although it is not pressure compensated. The NCEBOBV maintains compatibility across 2-port flow control cartridges, offering the same flow path and cavity specifications for a given frame size, although extension dimensions may vary. The valve's design includes a balanced adjustment mechanism for easy modification even under high-pressure conditions and a sharp-edged orifice to minimize variations due to changes in fluid viscosity. It is crucial to note that cartridges with EPDM seals are specifically intended for use with phosphate ester fluids and should not be exposed to petroleum-based fluids as this can cause seal damage. The floating style construction of the valve minimizes binding risks due to installation torque or machining variations. This model fits into the T-5A cavity and has a capacity of 12 gpm (45 L/min) with a maximum operating pressure of 5000 psi (350 bar). The maximum leakage rate at 110 SUS (24 cSt) is minimal at 10 drops/min (0.7 cc/min). The adjustment range from fully closed to open involves five counterclockwise turns, with specific torque requirements for installation and adjustments provided. Weighing in at 0.40 lb (0.20 kg), this cartridge uses Viton seals as part of its construction, ensuring reliable performance in demanding environments.

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.
