The Sun Hydraulics NCECOEV (Material Number: NCECOEV) is a needle valve with reverse flow check, designed to provide precise flow regulation in hydraulic systems. This valve features an adjustable orifice that allows for infinite control from fully closed to the maximum orifice diameter, ensuring optimal performance for various applications. It incorporates an integral high-capacity check valve that facilitates unrestricted flow from port 2 to port 1, although it is not pressure compensated. The NCECOEV model is part of the 2-port flow control cartridges series, which are physically and functionally interchangeable with other cartridges of the same frame size, though extension dimensions from the mounting surface may differ. The valve's design includes a balanced adjustment mechanism for easy operation even at high pressures, and a sharp-edged orifice to minimize flow variations caused by changes in fluid viscosity. Sun Hydraulics' floating style construction minimizes internal binding due to excessive installation torque or machining variations. The NCECOEV operates within a maximum pressure of 5000 psi (350 bar) and has a capacity of 3 gpm (11 L/min). It features minimal leakage at 110 SUS (24 cSt), with a maximum leakage rate of 5 drops/min (0.3 cc/min). The valve's specifications include a cavity size T-5A, Series 2, and it requires specific installation torques: 45 - 50 lbf ft (61 - 68 Nm) for the valve and 80 - 90 lbf in (9 - 10 Nm) for the locknut. Adjustments are made using an internal hex screw with dimensions of 5/32 in. (4 mm), while the locknut hex size is 9/16 in. (15 mm). The model weighs approximately .40 lb (.20 kg) and utilizes Viton seals with seal kit 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.
- 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.
