The Sun Hydraulics NCEBOCN (NCEBOCN) is a needle valve with a reverse flow check, designed to provide precise flow regulation with an adjustable orifice. This component allows for infinite adjustment from fully closed to the maximum orifice diameter, making it highly versatile for various applications. The valve features an integral high-capacity check valve that ensures unrestricted flow from port 2 to port 1, although it is not pressure compensated. This means the fixed orifice size regulates flow in proportion to the square root of the pressure differential across ports 1 and 2. The needle valve's balanced adjustment mechanism facilitates easy adjustments even under high pressures, while its sharp-edged orifice design minimizes flow variations due to viscosity changes. This particular model incorporates EPDM seals, suitable for systems utilizing phosphate ester fluids, but they are susceptible to damage when exposed to petroleum-based fluids and lubricants. Utilizing Sun's floating style construction, the design minimizes internal part binding that can occur due to excessive installation torque or machining variations in cavity/cartridge interfaces. This Series 2 cartridge fits into a T-5A cavity and has a capacity of 12 gpm (45 L/min) with a maximum operating pressure of 5000 psi (350 bar). It offers a minimal leakage rate of up to 10 drops/min at 110 SUS (24 cSt). The valve requires specific installation and adjustment torques, ensuring secure fitting and optimal performance in 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.
