The Sun Hydraulics NCEBLBV (Material Number: NCEBLBV) is a versatile needle valve with a reverse-flow check, designed for precise flow regulation in hydraulic systems. This valve features an adjustable orifice that allows for infinite control from fully closed to maximum opening, making it suitable for applications requiring fine-tuned flow management. The integral high-capacity check valve ensures unrestricted flow from port 2 to port 1. While it is not pressure compensated, its balanced adjustment mechanism facilitates easy operation even under high pressure conditions. The sharp-edged orifice design minimizes the impact of viscosity changes on flow rates. It is important to note that cartridges with EPDM seals are specifically intended for use with phosphate ester fluids and should not be exposed to petroleum-based substances, as this can damage the seals. This needle valve incorporates Sun's floating style construction, which reduces the risk of internal component binding due to excessive installation torque or machining variations in the cavity and cartridge. It fits into a T-5A cavity and belongs to Series 2, offering a capacity of 12 gpm (45 L/min) at a maximum operating pressure of 5000 psi (350 bar). The valve's leakage rate is minimal at 10 drops/min (0.7 cc/min) under specified conditions. For adjustments, it requires up to five counterclockwise turns from fully closed to fully open, and the valve hex size is 1-1/8 inches (28.6 mm). Proper installation torque ranges between 45-50 lbf ft (61-68 Nm), while the locknut torque should be maintained between 80-90 lbf in (9-10 Nm). This model weighs approximately 0.40 lb (0.20 kg), and for maintenance purposes, a Viton seal kit can be used with part number 990203006.

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.
