The Sun Hydraulics RVBBCNN (RVBBCNN) is a three-port, normally closed modulating element with relief, designed to perform dual functions when used in conjunction with an external orifice. Primarily, it acts as a bypass compensator that manages priority flow into a circuit based on the external orifice's settings. Any input flow exceeding this priority flow is redirected to tank port 2. Additionally, if the pressure at inlet port 1 exceeds the valve setting, it functions as a conventional relief valve. The compensating pressure for all ranges is set at 50 psi (3.5 bar). Its performance curve indicates that the X axis represents system pressure while the Y axis shows the pressure differential created across the control orifice, with curves depicting various bypass flows (pump flow minus control flow). The valve's capacity and performance are determined by bypass flow, independent of control flow. The valve fits into cavity T-163A Series 0 and has a capacity of 5 gpm (20 L/min), with factory pressure settings established at 4 gpm (15 L/min). It can handle a maximum operating pressure of 5000 psi (350 bar) and has a typical response time of 10 ms. Maximum valve leakage at 110 SUS (24 cSt) is rated at 2 in\u00b3/min (30 cc/min) at 1000 psi (70 bar). Adjustment can be made via number of clockwise turns to increase setting up to five turns. The valve hex size measures .34 in. (19.1 mm) and requires an installation torque between 20 - 25 lbf ft (27 - 33 Nm). Additional specifications include an adjustment screw internal hex size of .532 in. (4 mm), locknut hex size of .916 in. (15 mm), and locknut torque between 80 - 90 lbf in. (9 - 10 Nm). The model weighs .30 lb (.15 kg) and uses Viton seal kits for cartridge sealing needs.
