The Sun Hydraulics NCECYCV (NCECYCV) is a versatile needle valve with a reverse-flow check, designed to provide precise flow regulation in hydraulic systems. This component is fully adjustable, allowing for infinite control from a completely closed position to its maximum orifice diameter. It features an integral high-capacity check valve that ensures unrestricted flow from port 2 to port 1, although it is not pressure compensated. The NCECYCV is compatible with all 2-port flow control cartridges of the same frame size, offering functional interchangeability, though extension dimensions may vary based on the mounting surface. The valve operates by regulating flow in proportion to the square root of the pressure differential across ports 1 and 2, given its non-compensating nature. It includes a balanced adjustment mechanism for easy operation even under high pressures and utilizes a sharp-edged orifice design to minimize flow variations due to changes in fluid viscosity. The floating style construction reduces the risk of internal parts binding from excessive installation torque or machining variations. This model fits into a T-5A cavity and can handle a capacity of up to 3 gpm (11 L/min) with a maximum operating pressure of 5000 psi (350 bar). The leakage at maximum viscosity is minimal at just 5 drops/min (0.3 cc/min). The valve's adjustment range spans up to 5.5 counterclockwise turns from fully closed to open, and it features specific torque requirements for installation and adjustments: 45-50 lbf ft for installation and 80-90 lbf in for the locknut. With a weight of .40 lb (.20 kg), this needle valve uses Viton seal kits for optimal performance in various applications where precise flow control is critical.

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.
