The Sun Hydraulics NCECOCV (Material Number: NCECOCV) is a needle valve with a reverse flow check, designed for precise flow regulation in hydraulic systems. This component features an adjustable orifice, allowing for infinite adjustment from fully closed to the maximum orifice diameter, and includes an integral high-capacity check valve that ensures unrestricted flow from port 2 to port 1. Notably, this valve is not pressure compensated. It boasts interchangeability with all 2-port flow control cartridges of the same frame size, although cartridge extension dimensions may vary. The valve's design includes a balanced adjustment mechanism for easy handling even under high pressures, and its sharp-edged orifice minimizes flow variations due to changes in fluid viscosity. The NCECOCV model incorporates Sun's floating style construction to reduce the risk of internal binding caused by installation torque or machining variations. It has a capacity of 3 gpm (11 L/min) with a maximum operating pressure of 5000 psi (350 bar). The valve allows for a maximum leakage rate of 5 drops per minute at 110 SUS (24 cSt). With an adjustment range spanning five and a half counterclockwise turns from fully closed to open, it requires specific torque settings for installation and locknut adjustments. This model fits into cavity T-5A and has specific dimensional requirements for installation, including hex sizes and torque specifications for both the valve body and adjustment components. The unit weighs approximately .40 lb (.20 kg) and is compatible with Viton seal kits. Overall, the Sun Hydraulics NCECOCV needle valve is engineered for reliability and precision in controlling hydraulic fluid flows within various applications.

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.
