The Sun Hydraulics NFDCYAE (Material Number: NFDCYAE) is a versatile needle valve designed for precise flow regulation in hydraulic systems. This fully adjustable orifice allows for infinite adjustment from fully closed to the maximum orifice diameter, making it suitable for use as a flow control or shutoff valve. It is important to note that this valve is not pressure compensated, thus the flow regulation is dependent on the square root of the pressure differential across ports 1 and 2. The NFDCYAE model features a balanced adjustment mechanism, facilitating easy adjustments even under high-pressure conditions. Its sharp-edged orifice design effectively minimizes flow variations due to changes in fluid viscosity. The bidirectional flow path, with a preferred direction from port 1 to port 2, ensures compatibility with other flow controls. This cartridge valve has no leakage when the adjustment mechanism is set to the shutoff position, offering reliable performance in various applications. It can handle a maximum operating pressure of up to 5000 psi (350 bar) and supports a capacity of 12 gpm (45 L/min). The valve's installation requires a torque of 45-50 lbf ft (61-68 Nm) with an internal hex size of 5/32 inches for adjustment screw and a locknut hex size of 9/16 inches requiring a torque of 80-90 lbf in (9-10 Nm). Weighing approximately .60 lb (0.30 kg), this model comes with Viton seals as part of its cartridge seal kit (part number: 990203006), ensuring compatibility with specific fluid types while resisting exposure to petroleum-based substances. The NFDCYAE's robust construction and efficient design make it an ideal choice for precise hydraulic flow management tasks.
