The Sun Hydraulics NCECYBN (NCECYBN) is a versatile needle valve with reverse flow check designed for precise flow regulation in hydraulic systems. This component features an adjustable orifice that allows for infinite control from fully closed to the maximum orifice diameter, making it ideal for applications requiring fine-tuned flow adjustments. The integral high-capacity check valve ensures unrestricted flow from port 2 to port 1, although it is important to note that this valve is not pressure compensated. The NCECYBN model is part of Sun's 2-port flow control cartridge range, which are designed to be physically and functionally interchangeable within the same frame size, although extension dimensions may vary. This needle valve utilizes a balanced adjustment mechanism that facilitates easy adjustments even under high pressure conditions. Its sharp-edged orifice design helps minimize variations in flow due to changes in fluid viscosity. Additionally, the floating style construction reduces the risk of internal parts binding caused by excessive installation torque or machining variations in the cavity or cartridge. The NCECYBN has a maximum capacity of 3 gpm (11 L/min) and can withstand operating pressures up to 5000 psi (350 bar). It exhibits minimal leakage, with a maximum valve leakage at 110 SUS (24 cSt) of just 5 drops per minute (0.3 cc/min). For installation, it requires a torque of 45-50 lbf ft (61-68 Nm), and its adjustment screw has an internal hex size of 5/32 inches (4 mm). The locknut requires a torque of 80-90 lbf in (9-10 Nm), with a hex size of 9/16 inches (15 mm). Weighing approximately 0.40 lb (0.20 kg), this model comes with Viton seal kits available for maintenance needs.

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.
