The Sun Hydraulics NCECLEN (Material Number: NCECLEN) is a needle valve with a reverse-flow check, designed for precise flow regulation. This valve is infinitely adjustable from fully closed to the maximum orifice diameter, allowing for tailored flow control. It features an integral high-capacity check valve that permits unrestricted flow from port 2 to port 1. However, it is important to note that this model is not pressure compensated. The NCECLEN model is part of the 2-port flow control cartridge series, which are interchangeable in terms of flow path and cavity dimensions, although extension dimensions may vary. The valve operates on a balanced adjustment mechanism, ensuring ease of adjustment even under high-pressure conditions. Its sharp-edged orifice design minimizes variations in flow due to changes in viscosity. Additionally, Sun's floating style construction reduces the risk of internal parts binding from excessive installation torque or machining variations. Key specifications include a cavity size of T-5A and a series capacity of 3 gpm (11 L/min) with a maximum operating pressure of 5000 psi (350 bar). The maximum valve leakage at 110 SUS (24 cSt) is minimal at 5 drops/min (0.3 cc/min). The adjustment range spans 5.5 counterclockwise turns from fully closed to fully open, with specific torque requirements for installation and adjustments. The NCECLEN model weighs approximately 0.40 lb (0.20 kg) and uses Viton seals for durability and performance consistency under various conditions.

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.
