The Sun Hydraulics NFCCLIE (NFCCLIE) is a versatile needle valve designed to regulate flow through fully adjustable orifices. This model allows for precise control from fully closed to the maximum orifice diameter, functioning effectively as both a flow control and a shutoff valve. It features a balanced adjustment mechanism that facilitates easy adjustments even under high pressure conditions. The sharp-edged orifice design ensures minimal flow variations due to changes in fluid viscosity, and the bidirectional flow path offers flexibility, with the preferred direction being from port 1 to port 2 for compatibility with other flow controls. This needle valve is non-pressure compensated, meaning that the fixed orifice size regulates flow proportionally to the square root of the pressure differential across ports 1 and 2. The NFCCLIE model boasts a maximum operating pressure of 5000 psi (350 bar) and can handle a capacity of up to 7 gpm (.19 inch/28 L/min). Its compact design includes a valve hex size of .78 inches (22.2 mm) and requires an installation torque between 30-35 lbf ft (41-47 Nm). The adjustment screw has an internal hex size of 5/32 inches (4 mm), while the locknut has a hex size of 9/16 inches (15 mm) with a torque specification of 80-90 lbf in (9-10 Nm). The model weighs .30 lb (.15 kg) and is compatible with EPDM seals for systems using phosphate ester fluids, although exposure to petroleum-based substances should be avoided to prevent seal damage.
