The Sun Hydraulics FXFALAN (Material Number: FXFALAN) is a fixed orifice, pressure-compensated flow control valve designed to provide precise flow regulation for both meter-in and meter-out applications, even under wide pressure fluctuations. This model allows users to specify a flow rating, which is factory set with an accuracy of \u00b110% of the requested setting. Additionally, it offers a tunable control option that provides a \u00b120% variation from the nominal factory preset flow. The adjustment can be made by turning clockwise to increase the flow rate. Its sharp-edged orifice design effectively minimizes variations in flow due to viscosity changes, ensuring consistent performance. The FXFALAN model features two-port flow control cartridges that are physically and functionally interchangeable within the same frame size, although cartridge extension dimensions may vary from the mounting surface. It incorporates Sun's floating style construction, which helps minimize internal part binding due to excessive installation torque or machining variations in the cavity/cartridge. Key specifications include a cavity size of T-18A, series 4 capacity with a maximum operating pressure of 5000 psi (350 bar), and a capacity of 50 gpm (200 L/min). The valve hex size is 1-5/8 inches (41.3 mm), with an installation torque requirement between 350-375 lbf ft (475-508 Nm). The adjustment screw features an internal hex size of 5/32 inches (4 mm), while the locknut hex size is 9/16 inches (15 mm), requiring a torque between 80-90 lbf in (9-10 Nm). The model weighs approximately 2.80 lb (1.30 kg) and uses Viton seal kits for optimal performance.
