The Sun Hydraulics NFDCLAN (Material Number: NFDCLAN) is a high-performance needle valve designed for precise flow regulation in hydraulic systems. This model offers fully adjustable orifices, allowing for infinite adjustment from fully closed to the maximum orifice diameter. It functions effectively as both a flow control and shutoff valve, though it is not pressure compensated. The NFDCLAN model ensures bidirectional flow with a preferred path from port 1 to port 2, which supports interchangeability with other flow control devices. The sharp-edged orifice design minimizes variations due to viscosity changes, providing consistent performance across different operating conditions. A notable feature of this needle valve is its balanced adjustment mechanism, which facilitates easy adjustments even under high-pressure scenarios, with a maximum operating pressure of 5000 psi (350 bar). The valve's installation requires a torque of 45 - 50 lbf ft (61 - 68 Nm), and it features an internal hex size of 5/32 inch for the adjustment screw. For secure locking, the locknut hex size is 9/16 inch with a torque specification of 80 - 90 lbf in (9 - 10 Nm). The valve's hex size measures at 1-1/8 inch (28.6 mm), ensuring compatibility with standard fittings. Sun Hydraulics has designed this model to be physically and functionally interchangeable across various applications, making it versatile for different hydraulic systems. It comes equipped with EPDM seals suitable for phosphate ester fluid systems while cautioning against exposure to petroleum-based fluids that could damage the seals. Weighing approximately .60 lb (.30 kg), this needle valve combines robust construction with efficient performance capabilities, making it an excellent choice for precise fluid control in demanding environments.
