The Sun Hydraulics NFCCLDE (NFCCLDE) is a precision-engineered needle valve designed for regulating flow in hydraulic systems. This fully adjustable orifice valve allows for infinite adjustment from fully closed to the maximum orifice diameter, making it suitable for applications requiring precise flow control or complete shutoff capabilities. The NFCCLDE model is not pressure compensated, meaning that it regulates flow based on the square root of the pressure differential across its ports. It features a balanced adjustment mechanism that facilitates easy operation even under high pressures, and its sharp-edged orifice design minimizes variations in flow due to changes in fluid viscosity. The valve is bidirectional, although the preferred flow path is from port 1 to port 2, which ensures interchangeability with other flow control devices. Notably, there is no leakage when the adjustment mechanism is set to the shutoff position. This model fits into a Cavity T-13A Series 1 and has a capacity of up to 7 gpm (28 L/min) at a maximum operating pressure of 5000 psi (350 bar). The adjustment range spans 5.5 counterclockwise turns from fully closed to open. Installation requires a torque setting between 30-35 lbf ft (41-47 Nm), and the internal hex size for adjustments is 5/32 inch (4 mm). The locknut hex size measures 9/16 inch (15 mm) with a torque requirement of 80-90 lbf in (9-10 Nm). Weighing approximately .30 lb (.15 kg), this model can be configured with EPDM seals for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based substances.
