The Sun Hydraulics NCGCYDN (NCGCYDN) is a high-performance needle valve with a reverse flow check, designed to precisely regulate flow in hydraulic systems. This valve is fully adjustable from a closed position to the maximum orifice diameter, allowing for fine-tuned control of fluid flow. It features an integral high-capacity check valve that permits unrestricted flow from port 2 to port 1, making it versatile for various applications requiring directional control. Despite lacking pressure compensation, the valve's fixed orifice size effectively regulates flow in proportion to the square root of the pressure differential between ports 1 and 2. The NCGCYDN model incorporates a balanced adjustment mechanism for ease of use even under high-pressure conditions. Its sharp-edged orifice design helps minimize flow variations due to changes in fluid viscosity. The floating style construction reduces the risk of internal parts binding, which can occur due to excessive installation torque or machining variations. This model fits into Cavity T-18A and belongs to Series 4 with a capacity of 30 gpm (120 L/min) and can operate at pressures up to 5000 psi (350 bar). The maximum leakage rate at 110 SUS (24 cSt) is minimal at just 5 drops per minute. The valve allows for up to 5.5 counterclockwise turns from fully closed to fully open positions, providing substantial adjustability. Key specifications include a hex size of 1-5/8 inches for installation torque between 350 and 375 lbf ft, an internal hex size of 5/32 inches for adjustment screws, and a locknut hex size of 9/16 inches with a torque requirement of 80-90 lbf in. The model weighs approximately 3 pounds and uses Viton seals as part of its cartridge seal kit (990018006).

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.
