The Sun Hydraulics NCGCLCV (NCGCLCV) is a versatile needle valve with a reverse-flow check, designed to offer precise flow regulation. This component is fully adjustable, allowing for infinite modulation from fully closed to the maximum orifice diameter. It features an integral high-capacity check valve that ensures unrestricted flow from port 2 to port 1. Despite its advanced capabilities, it is important to note that this valve is not pressure compensated. Designed for interchangeability, all 2-port flow control cartridges share the same flow path and cavity dimensions for a given frame size, although extension dimensions may differ. The NCGCLCV model utilizes a balanced adjustment mechanism for easy tuning even under high-pressure conditions. Its sharp-edged orifice design effectively minimizes flow variations caused by changes in fluid viscosity. Furthermore, the Sun floating style construction reduces the risk of internal binding due to excessive installation torque or machining discrepancies in the cavity-cartridge interface. Key specifications include a T-18A cavity size and a Series 4 capacity of up to 30 gpm (120 L/min), withstanding a maximum operating pressure of 5000 psi (350 bar). The valve\u2019s leakage rate at 110 SUS (24 cSt) is minimal, at only 5 drops/minute (0.3 cc/min). Adjustment can be made over 5.5 counterclockwise turns from fully closed to open, with specific torque requirements for installation and locknut adjustments provided for optimal performance and reliability. The model weighs approximately 3 pounds (1.35 kg) and includes Viton seal kits as standard.
