The Sun Hydraulics NFCCYCN (Material Number: NFCCYCN) is a versatile needle valve designed for precise flow regulation in hydraulic systems. This fully adjustable orifice allows for infinite adjustment from a fully closed position to the maximum orifice diameter, making it suitable for use as both a flow control and shutoff valve. The NFCCYCN is not pressure compensated, meaning that the flow regulation is dependent on the pressure differential across ports 1 and 2, following the square root relationship. It features a balanced adjustment mechanism that facilitates easy tuning even under high-pressure conditions, up to a maximum operating pressure of 5000 psi (350 bar). The sharp-edged orifice design minimizes variations in flow due to changes in fluid viscosity, ensuring consistent performance. This needle valve supports bidirectional flow, with port 1 to port 2 being the preferred path for interchangeability with other flow controls. It guarantees zero leakage when the adjustment mechanism is turned to the shutoff position. The NFCCYCN model comes equipped with EPDM seals suitable for systems utilizing phosphate ester fluids but should be kept away from petroleum-based fluids which can damage these seals. The cartridge fits into a T-13A cavity and offers a capacity of up to 7 gpm (28 L/min), with an adjustment range of 5.5 counterclockwise turns from fully closed to fully open. For installation, it requires a valve hex size of 7/8 inches (22.2 mm) and should be torqued between 30 - 35 lbf ft (41 - 47 Nm). The internal hex size for the adjustment screw is 5/32 inches (4 mm), while the locknut hex size is 9/16 inches (15 mm), requiring a torque of 80 - 90 lbf in (9 -10 Nm). Weighing approximately .30 lb (.15 kg), this model offers robust performance in hydraulic applications demanding precise control over fluid flow.
