The Sun Hydraulics FXAAXBN (FXAAXBN) is a fixed orifice, pressure-compensated flow control valve designed for precise flow regulation in meter-in or meter-out applications, even under wide pressure fluctuations. This model offers a variety of flow rates, with specific tolerances for each: A Flow Rate at 32 cc/min, B Flow Rate at 40 cc/min, D and F Flow Rates at 48 cc/min, H and J Flow Rates at 64 cc/min, and L Flow Rate at 72 cc/min. Featuring a sharp-edged orifice design, it minimizes flow variations due to viscosity changes. It can handle a maximum operating pressure of 5000 psi (350 bar) at ports 1 and 2. The cartridge incorporates Sun's floating style construction to reduce the risk of internal parts binding due to excessive installation torque or cavity/cartridge machining variations. It is housed in a T8A cavity and belongs to the P series with a capacity of .5 gpm (2 L/min). The valve hex size is .78 inches (22.2 mm), with an installation torque range between 25-30 lbf ft (35-40 Nm). For optimal performance in systems using phosphate ester fluids, cartridges with EPDM seals are recommended; exposure to petroleum-based fluids can damage these seals. This model also features compensating pressure via spring force equating to about 100 psi (7 bar), providing acceptable capacity without compromising circuit operation. In terms of installation, the product includes compatibility with Viton seal kits such as the 990008006. The FXAAXBN is engineered for accuracy within its specified range while maintaining efficiency across various hydraulic applications.
