The Sun Hydraulics NCECLDV (NCECLDV) is a versatile needle valve with reverse-flow check, designed to regulate flow through fully adjustable orifices. It allows for infinite adjustment from fully closed to the maximum orifice diameter, providing precise control over fluid flow. The valve features an integral high-capacity check valve that ensures unrestricted flow from port 2 to port 1. However, it is important to note that this model is not pressure compensated. The NCECLDV is part of the 2-port flow control cartridge series, which are both physically and functionally interchangeable within the same frame size, although dimensions may vary slightly from the mounting surface. This needle valve operates on the principle that its fixed orifice size will regulate flow proportionally to the square root of the pressure differential across ports 1 and 2. Its balanced adjustment mechanism facilitates easy adjustments even under high pressures. The sharp-edged orifice design minimizes variations in flow due to changes in fluid viscosity, enhancing its reliability in various conditions. Furthermore, it incorporates Sun's floating style construction, reducing the risk of internal parts binding due to excessive installation torque or machining variations. Key specifications include a cavity T-5A with a series capacity of 3 gpm (11 L/min) and a maximum operating pressure of 5000 psi (350 bar). The valve exhibits minimal leakage at specified conditions and features various adjustment parameters including a total of five counterclockwise turns from fully closed to open. It requires specific installation torque values and comes with a Viton seal kit for maintenance purposes. With its robust design and precise control capabilities, this needle valve is ideal for applications requiring reliable flow regulation in hydraulic systems.
