The Sun Hydraulics NCECYEV (NCECYEV) is a precision-engineered needle valve with a reverse flow check, designed to regulate flow through an adjustable orifice. This component is capable of managing flow from fully closed to the maximum orifice diameter, allowing for precise control in hydraulic systems. It features an integral high-capacity check valve that enables unrestricted flow from port 2 to port 1, though it does not offer pressure compensation. The NCECYEV model is part of Sun Hydraulics' 2-port flow control cartridge series, which are interchangeable in terms of flow path and cavity for a given frame size, although extension dimensions may differ. This needle valve employs a balanced adjustment mechanism for ease of use even under high pressure conditions and utilizes a sharp-edged orifice design to minimize the impact of viscosity changes on flow variations. The floating style construction helps prevent internal binding caused by excessive installation torque or machining variations. The valve fits into a T-5A cavity and has a capacity of 3 gpm (11 L/min) with a maximum operating pressure of 5000 psi (350 bar). It exhibits minimal leakage at 5 drops/min (0.3 cc/min) when using oil with viscosity at 110 SUS (24 cSt). Key specifications include an adjustment range requiring up to five and a half counterclockwise turns from fully closed to open, a valve hex size of 1-1/8 inches (28.6 mm), and an installation torque specification between 45-50 lbf ft (61-68 Nm). The internal hex size for the adjustment screw is 5/32 inches (4 mm), while the locknut hex size is 9/16 inches (15 mm), needing a torque of 80-90 lbf in (9-10 Nm). This model weighs approximately .40 lb (.20 kg) and uses Viton seal kits identified by part number 990203006.

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.
