The Sun Hydraulics FDBAOAN (FDBAOAN) is a fully adjustable, pressure-compensated flow control valve designed for applications requiring precise flow regulation in meter-in or meter-out configurations, especially where significant pressure fluctuations occur. This model features an integral high-capacity check valve for unrestricted reverse flow from port 2 to port 1. Its design allows infinite adjustability from nearly closed to maximum flow, with a balanced adjustment mechanism that facilitates easy adjustments even under high-pressure conditions. The sharp-edged orifice minimizes variations in flow due to changes in fluid viscosity, ensuring consistent performance. This cartridge is interchangeable with other 2-port flow control cartridges of the same frame size, although extension dimensions may vary. It fits into a T-13A cavity and belongs to Series 1 with a capacity of up to 6 gpm (23 L/min) and can operate at a maximum pressure of 5000 psi (350 bar). The adjustment mechanism allows for up to 5.5 counterclockwise turns from fully closed to fully open. Installation requires specific torque settings: the valve hex size is 7/8 inch (22.2 mm) with an installation torque of 30 - 35 lbf\u00b7ft (41 - 47 Nm), while the locknut hex size is 9/16 inch (15 mm) requiring a torque of 80 - 90 lbf\u00b7in (9 - 10 Nm). The model weighs approximately .40 lb (.20 kg). For systems using phosphate ester fluids, cartridges with EPDM seals are recommended; exposure to petroleum-based fluids will damage these seals. The FDBAOAN ensures minimal leakage at .1 gpm (.4 L/min) when shut off and maintains accuracy within \u00b110%, optimized by staying within the lower two-thirds of its range.
