The Sun Hydraulics NCECLEV (Material Number: NCECLEV) is a needle valve with a reverse flow check, designed for precise flow regulation in hydraulic systems. This valve offers infinite adjustability from fully closed to the maximum orifice diameter, allowing users to fine-tune flow rates as needed. It features an integral high-capacity check valve that permits unrestricted flow from port 2 to port 1, though it is important to note that the valve is not pressure compensated. The design ensures interchangeability with other 2-port flow control cartridges, maintaining the same flow path and cavity for a given frame size. The NCECLEV's balanced adjustment mechanism facilitates easy adjustments even under high-pressure conditions, while its sharp-edged orifice minimizes variations due to viscosity changes. The floating style construction reduces the risk of internal parts binding from excessive installation torque or machining variations in the cavity or cartridge. Key specifications include a T-5A cavity series with a capacity of 3 gallons per minute (11 liters per minute) and a maximum operating pressure of 5000 psi (350 bar). The valve has a leakage rate of 5 drops per minute at 110 SUS (24 cSt). Physical dimensions include a hex size of 1-1/8 inches and an installation torque range of 45-50 lbf-ft. Adjustment is controlled by an internal hex screw requiring a 5/32-inch tool, and it includes a locknut with a torque specification of 80-90 lbf-in. Weighing in at .40 lbs., this model also comes with Viton seal kits available for maintenance needs.

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.
- 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.
