The Sun Hydraulics RVBBCAV (Material Number: RVBBCAV) is a versatile hydraulic component designed to perform dual functions when used with an external orifice. It acts as a three-port normally closed modulating element with relief capabilities. The mainstage of this valve serves as a bypass compensator that regulates priority flow into a circuit, which is determined by the external orifice. Any input flow exceeding the priority flow is redirected to the tank port 2. Additionally, if the pressure at inlet port 1 exceeds the valve's set threshold, it functions as a standard relief valve. This model features a compensating pressure of 50 psi (3.5 bar) across all ranges and offers detailed performance curves that illustrate system pressure versus pressure differential across the control orifice. The valve's capacity and performance are dictated by bypass flow, independent of control flow. The RVBBCAV model fits into cavity T-163A and has a series 0 capacity of 5 gpm (20 L/min). It can handle a maximum operating pressure of up to 5000 psi (350 bar) and exhibits a typical response time of 10 milliseconds. The maximum allowable leakage at 110 SUS (24 cSt) is specified at 2 in\u00b3/min (30 cc/min) at 1000 psi (70 bar). For adjustments, it requires approximately five clockwise turns to increase settings, with installation torque ranging from 20 to 25 lbf ft (27 to 33 Nm). The internal hex size for adjustment screws is ^5/32 in. (4 mm), while the locknut hex size measures ^9/16 in. (15 mm), requiring torque between 80 and 90 lbf in. (9 to 10 Nm). This model weighs approximately .30 lb (.15 kg) and comes with Viton seal kits available under part number: 990-163-006.
