The Sun Hydraulics FDBAYCN (FDBAYCN) is a fully adjustable, pressure-compensated flow control valve with a reverse flow check designed for precise flow regulation in meter-in or meter-out applications, especially where wide pressure fluctuations occur. This model allows for infinite adjustment from nearly closed to maximum flow, ensuring adaptability to various operational demands. An integral high-capacity check valve ensures unrestricted flow from port 2 to port 1, enhancing its functionality. The cartridges are interchangeable across similar frame sizes with consistent flow paths and cavities, although the extension dimensions may vary. The balanced adjustment mechanism facilitates easy adjustments even at high pressures, and the sharp-edged orifice design minimizes variations due to viscosity changes. It features minimal leakage at .1 gpm when set to the shutoff position. Compatible with systems using phosphate ester fluids, it requires EPDM seals and should not be exposed to petroleum-based fluids as this will damage the seals. The FDBAYCN fits into a T-13A cavity and belongs to Series 1 with a capacity of 6 gpm (23 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). The adjustment mechanism allows for 5.5 counterclockwise turns from fully closed to fully open. Installation requires a torque of 30 - 35 lbf ft (41 - 47 Nm), while the locknut needs an application of 80 - 90 lbf in (9 - 10 Nm). Weighing just .40 lbs (.20 kg), it is compact yet robust enough for demanding applications. For optimal performance accuracy is maintained within \u00b110%, though production testing sets this at \u00b15% under controlled conditions.
