The Sun Hydraulics NCEBLCN (NCEBLCN) is a needle valve with a reverse-flow check that offers precise flow regulation through an adjustable orifice, which can be set from fully closed to its maximum diameter. This model includes a high-capacity check valve that allows unrestricted flow from port 2 to port 1, although it is not pressure compensated. Designed for interchangeability, all two-port flow control cartridges share the same flow path and cavity size for a given frame size, though extension dimensions may differ. The NCEBLCN features a balanced adjustment mechanism for easy handling even under high pressure conditions, and its sharp-edged orifice minimizes variations due to viscosity changes. This model is particularly compatible with systems using phosphate ester fluids when equipped with EPDM seals; however, it is important to avoid exposure to petroleum-based fluids as they can damage the seals. The floating style construction reduces the risk of internal binding due to excessive installation torque or machining variations. Key specifications include a capacity of 12 gpm (45 L/min) at .25 inch (6.4 mm), withstanding up to 5000 psi (350 bar) of operating pressure. It has minimal leakage at high pressure, with a maximum valve leakage rate of 10 drops/minute at 110 SUS (24 cSt). The valve requires specific installation and adjustment torques: installation torque ranges between 45-50 lbf ft (61-68 Nm), while the locknut torque is between 80-90 lbf in (9-10 Nm). The adjustment screw uses an internal hex size of 5/32 inch (4 mm), and the locknut hex size is 9/16 inch (15 mm). The unit weighs approximately .40 lb (.20 kg) and uses Viton seal kits like the cartridge model 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.
