The Sun Hydraulics NCECKEV (Material Number: NCECKEV) is a needle valve with a reverse flow check designed for precise flow regulation. This valve features a fully adjustable orifice, allowing for infinite adjustment from fully closed to the maximum orifice diameter. It incorporates an integral high-capacity check valve that permits unrestricted flow from port 2 to port 1, though it is not pressure compensated. The NCECKEV model is part of Sun's 2-port flow control cartridges, which are interchangeable in terms of flow path and cavity for a given frame size, although extension dimensions may vary. This needle valve regulates flow based on the square root of the pressure differential across its ports due to its non-compensating nature. The design includes a balanced adjustment mechanism for easy tuning even under high pressures and features a sharp-edged orifice to minimize variations due to viscosity changes. Sun's floating style construction helps prevent internal binding caused by excessive installation torque or machining variations. The valve fits into a T-5A cavity and offers a capacity of 3 gpm (11 L/min) with a maximum operating pressure of 5000 psi (350 bar). It maintains minimal leakage at 5 drops/minute at 110 SUS (24 cSt). For installation, the valve requires a hex size of 1-1/8 inches and an installation torque between 45-50 lbf-ft. The adjustment screw has an internal hex size of 5/32 inches with up to five counterclockwise turns from fully closed to open. Additionally, the locknut requires a hex size of 9/16 inches and torque between 80-90 lbf-in. The NCECKEV model weighs approximately .40 lb (.20 kg) and uses Viton seals with seal kit number 990203006 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.
