The Sun Hydraulics NFCCLCE (NFCCLCE) is a precision needle valve designed to provide fully adjustable flow control in hydraulic systems. This product features an infinitely adjustable orifice, allowing the user to regulate flow from fully closed to the maximum orifice diameter, although it is not pressure compensated. As a versatile component, it can be used as either a flow control or shutoff valve and is interchangeable with other 2-port flow control cartridges of the same frame size. The NFCCLCE operates on a principle where the fixed orifice size regulates flow proportionally to the square root of the pressure differential between ports 1 and 2. It includes a balanced adjustment mechanism that facilitates easy adjustments even under high pressures, and its sharp-edged orifice design minimizes variations in flow due to changes in fluid viscosity. The valve's bidirectional flow path ensures flexibility in application, with a preferred direction from port 1 to 2 for compatibility with other controls. It guarantees no leakage when fully closed, making it reliable for critical applications. This model has a capacity of 7 gpm (28 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). The adjustment range spans up to 5.5 counterclockwise turns from fully closed to open. Installation requires specific torque settings for both the valve (30-35 lbf ft) and locknut (80-90 lbf in), ensuring secure assembly. The NFCCLCE is lightweight at .30 lb (.15 kg) and compatible with EPDM seals for systems using phosphate ester fluids, although care must be taken as these seals are susceptible to damage from petroleum-based substances.
