The Sun Hydraulics NCEBLEN (Material Number: NCEBLEN) is a versatile needle valve with a reverse-flow check, designed to provide precise flow regulation in hydraulic systems. It offers fully adjustable orifices that can be fine-tuned from fully closed to the maximum orifice diameter, allowing for tailored flow control according to specific system requirements. The valve features an integral high-capacity check valve enabling unrestricted flow from port 2 to port 1, although it is important to note that it is not pressure compensated. This means the flow regulation is dependent on the pressure differential across ports 1 and 2, with adjustments made via a balanced mechanism for ease even under high pressures. The sharp-edged orifice design effectively minimizes variations in flow due to changes in fluid viscosity. This model is part of Sun's interchangeable 2-port flow control cartridge lineup, sharing common flow paths and cavity dimensions across similar frame sizes, though extension dimensions may differ. It incorporates Sun\u2019s floating style construction to reduce potential binding issues caused by installation torque or machining variations. The NCEBLEN model supports up to 12 gpm (45 L/min) capacity and operates at a maximum pressure of 5000 psi (350 bar). For sealing, cartridges configured with EPDM seals are suitable for use with phosphate ester fluids but are incompatible with petroleum-based substances. Installation specifics include a valve hex size of 1-1/8 inches (28.6 mm), requiring an installation torque of 45-50 lbf-ft (61-68 Nm). The adjustment screw uses an internal hex size of 5/32 inches (4 mm), while the locknut requires a hex size of 9/16 inches (15 mm) and torque between 80-90 lbf-in (9-10 Nm). The model weighs .40 lbs (.20 kg) and comes with Viton seal kits available under 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.
