The Sun Hydraulics NCECLCV (Material Number: NCECLCV) is a needle valve with a reverse-flow check, designed for precise flow regulation in hydraulic systems. This valve is fully adjustable from a closed position to the maximum orifice diameter, providing flexibility in controlling fluid flow. It features an integral high-capacity check valve that allows unrestricted flow from port 2 to port 1, ensuring efficient performance without pressure compensation. The NCECLCV model is part of the 2-port flow control cartridges that are interchangeable in terms of flow path and cavity size for a given frame size, although extension dimensions may vary. This needle valve operates on a non-compensating principle where the fixed orifice size regulates flow based on the square root of the pressure differential across ports 1 and 2. It incorporates a balanced adjustment mechanism for easy operation even under high pressures, while its sharp-edged orifice design minimizes flow variations due to viscosity changes. The floating style construction reduces the risk of internal binding from excessive installation torque or machining variations. Key specifications include a capacity of 3 gpm (11 L/min) with a maximum operating pressure of 5000 psi (350 bar). The valve has minimal leakage at standard viscosity levels and requires specific torque values for installation and adjustment. Weighing just .40 lb (.20 kg), it is compact yet robust, making it suitable for various applications requiring precise fluid control. This model also supports Viton seal kits for enhanced durability and compatibility with different hydraulic fluids.
