The Sun Hydraulics NFCCHDV (Material Number: NFCCHDV) is a highly versatile needle valve designed for precise flow regulation in hydraulic systems. This fully adjustable orifice can be fine-tuned from a completely closed position to the maximum orifice diameter, offering infinite adjustment capabilities. It is important to note that the NFCCHDV is not pressure compensated, meaning it can function both as a flow control and a shutoff valve but will regulate flow based on the square root of the pressure differential across its ports. The valve's sharp-edged orifice design minimizes flow variations due to changes in fluid viscosity, ensuring consistent performance. Its balanced adjustment mechanism allows for smooth operation even at high pressures, and there is no leakage when the valve is fully closed. The NFCCHDV features bidirectional flow paths, with the preferred direction being from port 1 to port 2 for compatibility with other flow control devices. It boasts a maximum operating pressure of 5000 psi (350 bar) and can handle capacities up to 7 gpm (28 L/min). The valve requires specific installation torques and comes with detailed specifications for adjustment screw sizes and locknut torque settings, ensuring proper setup and maintenance. This model is also compatible with EPDM seals for systems utilizing phosphate ester fluids, though caution should be taken as these seals are not suitable for petroleum-based fluids. With its robust construction and precise control capabilities, the Sun Hydraulics NFCCHDV needle valve is an essential component for applications requiring reliable hydraulic flow management.
