The Sun Hydraulics RVBBKBV (Material Number: RVBBKBV) is a three-port normally closed modulating element with relief, designed to provide dual functions when used with an external orifice. This component acts as a bypass compensator in the main stage, controlling priority flow into a circuit as dictated by the external orifice. Any input flow exceeding the priority flow is redirected to tank port 2. Additionally, if the pressure at inlet port 1 exceeds the valve setting, it functions as a standard relief valve. The compensating pressure across all ranges is maintained at 50 psi (3.5 bar). The performance curve indicates system pressure on the X-axis and pressure differential across the control orifice on the Y-axis, with various curves representing differing bypass flows\u2014the capacity and performance hinge on this bypass flow rather than control flow. Key specifications include a cavity size of T-163A Series 0, with a capacity of 5 gpm (20 L/min). The factory pressure settings are established at 4 gpm (15 L/min), and it can handle a maximum operating pressure of 5000 psi (350 bar). It boasts a typical response time of 10 milliseconds and has minimal leakage at maximum valve leakage rates of 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). Adjustment for increasing settings involves up to five clockwise turns. The valve hex size is .34 inches (19.1 mm), requiring an installation torque of between 20 to 25 lbf-ft (27 to 33 Nm). The adjustment screw features an internal hex size of .532 inches (4 mm), while the locknut hex size is .916 inches (15 mm) with an associated torque range of 80 to 90 lbf-in (9 to 10 Nm). This model weighs approximately .30 lb (.15 kg) and utilizes Viton seal kits under cartridge number: 990163006.
