The Sun Hydraulics NCEBLDV (NCEBLDV) is a versatile needle valve with a reverse-flow check, designed to provide precise flow regulation in hydraulic systems. This component features an adjustable orifice that can be infinitely set from fully closed to the maximum orifice diameter, allowing for tailored flow control. The integrated high-capacity check valve ensures unrestricted flow from port 2 to port 1, although it is important to note that this valve is not pressure compensated. This means that the flow rate through the valve is influenced by the pressure differential between ports 1 and 2, following the square root relationship. A significant feature of this needle valve is its balanced adjustment mechanism, which facilitates easy adjustments even under high-pressure conditions. The sharp-edged orifice design minimizes variations in flow due to changes in fluid viscosity, ensuring consistent performance. The product's construction employs Sun's floating style design, reducing the risk of internal part binding from excessive installation torque or machining variations. The NCEBLDV model fits into a T-5A cavity and belongs to Series 2 with a capacity of handling up to 12 gpm (45 L/min) at a maximum operating pressure of 5000 psi (350 bar). It has minimal leakage rates and requires specific installation torques for optimal performance. For systems using phosphate ester fluids, cartridges with EPDM seals are recommended; however, these seals are not compatible with petroleum-based fluids. The valve's compact design includes specifications for hex sizes and torque settings for both the adjustment screw and locknut, providing detailed guidance for installation and maintenance.

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.
