The Sun Hydraulics RVBBKQV (RVBBKQV) is a versatile 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, controlling priority flow into a circuit as determined by the external orifice. Any input flow exceeding this priority flow is directed to tank port 2. Additionally, if pressure at inlet port 1 increases to the valve's preset level, it functions as a standard relief valve. The compensating pressure for all ranges is set at 50 psi (3.5 bar). The performance curve of this valve is explained by its system pressure (X-axis) and the pressure differential across the control orifice (Y-axis), with various curves indicating different bypass flows. The valve's capacity and performance are primarily determined by bypass flow rather than control flow. It features a cavity T-163A series with a capacity of 5 gpm (20 L/min) and can operate at a maximum pressure of 5000 psi (350 bar). Typical response time is around 10 ms, and maximum valve leakage at 110 SUS (24 cSt) is rated at 2 in\u00b3/min (30 cc/min) under 1000 psi (70 bar). Adjustment involves up to five clockwise turns to increase settings, with specific torque requirements for installation and adjustment components: valve hex size is .34 in. (19.1 mm), installation torque between 20-25 lbf ft (27-33 Nm), internal hex size for adjustment screw is .532 in. (4 mm), locknut hex size is .916 in. (15 mm), and locknut torque ranges from 80-90 lbf in. (9-10 Nm). The model weighs approximately .30 lb (.15 kg) and utilizes Viton seal kits for optimal performance under specified conditions.
