The Sun Hydraulics NCEBOCV (Material Number: NCEBOCV) is a needle valve with a reverse-flow check, designed to provide precise flow regulation. This valve features an adjustable orifice that allows for infinite adjustability from fully closed to the maximum orifice diameter, making it versatile for various applications requiring controlled flow rates. An integral high-capacity check valve enables unrestricted flow from port 2 to port 1. The valve is non-pressure compensated, meaning the fixed orifice size regulates flow based on the square root of the pressure differential across ports 1 and 2. It incorporates a balanced adjustment mechanism for ease of use even at high pressures and features a sharp-edged orifice design to reduce flow variations due to changes in fluid viscosity. The NCEBOCV model is compatible with systems using phosphate ester fluids when equipped with EPDM seals but should not be exposed to petroleum-based fluids as they can damage the seals. The construction includes Sun's floating style design, which minimizes internal binding due to installation torque or machining variations. The cartridge has a capacity of 12 gpm (45 L/min) and can operate at pressures up to 5000 psi (350 bar). It has a maximum valve leakage rate of 10 drops/min (0.7 cc/min) at 110 SUS (24 cSt). The valve's dimensions include a hex size of 1-1/8 inches and an installation torque range of 45-50 lbf ft (61-68 Nm). For adjustments, it requires up to five counterclockwise turns from fully closed to fully open, using an internal hex size of 5/32 inches for the adjustment screw and a locknut hex size of 9/16 inches with a torque requirement of 80-90 lbf in (9-10 Nm). The model weighs approximately .40 lb (0.20 kg) and uses Viton seal kits for maintenance 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.
