The Sun Hydraulics NCGCKDV (NCGCKDV) is a versatile needle valve with an integrated reverse-flow check, designed to regulate hydraulic flow with precision. This component features a fully adjustable orifice, allowing users to fine-tune flow rates from fully closed to the maximum orifice diameter. It includes a high-capacity check valve that permits unrestricted flow from port 2 to port 1, making it suitable for applications where reverse flow needs to be accommodated without restriction. Although not pressure compensated, this needle valve is physically and functionally interchangeable with other two-port flow control cartridges of the same frame size, though extension dimensions may vary. The NCGCKDV is equipped with a balanced adjustment mechanism for ease of use even under high-pressure conditions. Its sharp-edged orifice design minimizes variations in flow due to changes in fluid viscosity, ensuring consistent performance. The floating style construction helps prevent internal binding caused by excessive installation torque or machining variations. With a cavity size of T-18A and a series 4 capacity of up to 30 gpm (120 L/min), this model can handle pressures up to 5000 psi (350 bar). It offers minimal leakage at standard oil viscosity and allows for adjustment through 5.5 counterclockwise turns from fully closed to open. Installation requires specific torques for both the valve and locknut, ensuring secure mounting and operation. The NCGCKDV also benefits from additional features such as corrosion-resistant zinc-nickel plating and compatibility with Viton seal kits, enhancing its durability in demanding environments. With its robust specifications and reliable construction, this needle valve is an essential component for precise hydraulic flow control applications.

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.
