The Sun Hydraulics RVBBLBV (RVBBLBV) is a three-port normally closed modulating element with relief, designed to perform dual functions when used with an external orifice. This component acts as a bypass compensator, managing priority flow into a circuit as dictated by the external orifice, while excess input flow is redirected to tank port 2. Additionally, if pressure at inlet port 1 exceeds the valve setting, it functions as a standard relief valve. It offers compensating pressure across all ranges at 50 psi (3.5 bar). The performance curve illustrates system pressure on the X-axis and the pressure differential across the control orifice on the Y-axis, with various curves representing different bypass flows. Importantly, this valve's capacity and performance are influenced by bypass flow rather than control flow. The RVBBLBV operates within a T-163A cavity and provides a series 0 capacity of up to 5 gpm (20 L/min), with factory pressure settings established at 4 gpm (15 L/min). It has a maximum operating pressure of 5000 psi (350 bar) and typical response time of 10 milliseconds. Maximum valve leakage at 110 SUS (24 cSt) is rated at 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). To adjust settings, users can make up to five clockwise turns. The valve features a hex size of .34 inches (19.1 mm) for installation torque between 20-25 lbf ft (27-33 Nm), an internal hex size for adjustment screw of .532 inches (4 mm), and locknut hex size of .916 inches (15 mm), requiring locknut torque between 80-90 lbf in (9-10 Nm). The model weighs approximately .30 lb (.15 kg) and utilizes Viton seal kits.
