The Sun Hydraulics NCECOEN (Material Number: NCECOEN) is a needle valve with a reverse-flow check, designed for precise flow regulation in hydraulic systems. This fully adjustable orifice allows for flow control from fully closed to the maximum orifice diameter, making it versatile for various applications. It features an integral high-capacity check valve that ensures unrestricted flow from port 2 to port 1, although it is not pressure compensated. This model is part of the Series 2 cartridges, with a capacity of 3 gpm (11 L/min) and operates at a maximum pressure of 5000 psi (350 bar). The valve's design includes a balanced adjustment mechanism for easy modulation even under high-pressure conditions and a sharp-edged orifice to minimize flow variations due to viscosity changes. The Sun floating style construction reduces the risk of internal parts binding from excessive installation torque or machining variations. It fits into cavity T-5A and requires an installation torque of 45 \u2013 50 lbf ft (61 \u2013 68 Nm). The adjustment screw has an internal hex size of 5/32 in. (4 mm), and the locknut requires a torque of 80 \u2013 90 lbf in. (9 \u2013 10 Nm). The NCECOEN model weighs .40 lb (.20 kg) and uses Viton seals with seal kit number 990203006, ensuring compatibility with various hydraulic fluids and temperatures.

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.
