The Sun Hydraulics FXAAXJN (FXAAXJN) is a fixed orifice, pressure-compensated flow control valve designed for precise flow regulation in applications with significant pressure fluctuations. This model is suitable for both meter-in and meter-out scenarios, offering a range of flow rates to accommodate various system requirements. With a sharp-edged orifice design, it minimizes flow variations due to changes in fluid viscosity, ensuring consistent performance. The valve can handle pressures up to 5000 psi (350 bar) at ports 1 and 2, making it robust enough for demanding applications. The FXAAXJN features Sun's floating style construction, which reduces the risk of internal parts binding due to excessive installation torque or machining variations. It fits into a T8A cavity and belongs to the P series, with a capacity of 0.5 gpm (2 L/min). The valve's hex size is 7/8 inches (22.2 mm), and it requires an installation torque between 25-30 lbf-ft (35-40 Nm). It is equipped with Viton seals (seal kit number: 990008006) that are compatible with phosphate ester fluids but should not be exposed to petroleum-based products. Flow rate options include A at 2.0 in\u00b3/min (32 cc/min), B at 2.5 in\u00b3/min (40 cc/min), D and F at 3.0 in\u00b3/min (48 cc/min), H and J at 4.0 in\u00b3/min (64 cc/min), and L at 4.5 in\u00b3/min (72 cc/min). The valve maintains accuracy within \u00b110%, although production testing sets it to \u00b15% for better reliability under varying conditions. It's important to note that while this model offers effective flow control, it may not address heat issues unless properly sized within the system's specific parameters.
