The Sun Hydraulics NCGCHCV (NCGCHCV) is a versatile needle valve with a reverse-flow check, designed for precise flow regulation in hydraulic systems. This component offers infinite adjustability from fully closed to the maximum orifice diameter, allowing for tailored flow control. It features an integral high-capacity check valve that permits unrestricted flow from port 2 to port 1, making it suitable for applications requiring reliable reverse flow prevention. Notably, this model is not pressure compensated, meaning that the fixed orifice size regulates flow based on the square root of the pressure differential across ports 1 and 2. The Sun Hydraulics NCGCHCV incorporates a balanced adjustment mechanism, facilitating easy adjustments even under high-pressure conditions. Its sharp-edged orifice design minimizes flow variations due to changes in fluid viscosity, ensuring consistent performance. Additionally, the floating style construction reduces the risk of internal parts binding due to excessive installation torque or machining variations in the cavity-cartridge interface. This model fits into a Cavity T-18A and belongs to Series 4 with a capacity of 30 gpm (120 L/min). It operates at a maximum pressure of 5000 psi (350 bar) and exhibits minimal leakage at standard fluid viscosities. The valve features an adjustment range of up to five and a half counterclockwise turns from fully closed to fully open, with specific hex sizes for installation and adjustment tools. The NCGCHCV's robust construction and precise engineering make it an ideal choice for demanding hydraulic applications requiring reliable needle valve performance with reverse-flow capabilities.
