The Sun Hydraulics FXAAXDE (FXAAXDE) is a fixed orifice, pressure-compensated flow control valve that provides precise flow regulation for applications requiring consistent performance despite wide pressure fluctuations. This model is designed to handle maximum operating pressures of up to 5000 psi (350 bar) at ports 1 and 2, making it suitable for demanding hydraulic systems. The sharp-edged orifice design effectively minimizes flow variations caused by changes in fluid viscosity, ensuring reliable operation across different conditions. Available flow rates include options from 2.0 in\u00b3/min (32 cc/min) to 4.5 in\u00b3/min (72 cc/min), catering to various system requirements. The FXAAXDE incorporates Sun's floating style construction, which reduces the likelihood of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. It fits into a T8A cavity and belongs to the P series with a capacity of .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 to 30 lbf ft (35 to 40 Nm). This model is equipped with EPDM seals, suitable for systems using phosphate ester fluids; however, exposure to petroleum-based fluids can cause seal damage. Sun Hydraulics claims the flow controls have an accuracy of \u00b110%, though they are set to \u00b15% during production testing for better precision under varying customer conditions. For optimal accuracy, it is recommended to operate within the lower two-thirds of the flow range. The compensating pressure provided by the spring force in these controls is approximately 100 psi (7 bar), which balances capacity and proper circuit operation without excessive pressure drops that could generate heat and reduce efficiency.
