The Sun Hydraulics RVBBLAN (RVBBLAN) is a versatile three-port, normally closed modulating element with relief functionality. It serves dual purposes when integrated with an external orifice. Primarily, it acts as a bypass compensator that manages priority flow into the circuit, as dictated by the external orifice. Any input flow surpassing this priority flow is diverted to tank port 2. Additionally, if the pressure at inlet port 1 reaches the valve's predetermined setting, it functions as a conventional relief valve. The compensating pressure across all ranges is maintained at 50 psi (3.5 bar). The performance curve illustrates the relationship between system pressure and the pressure differential created across the control orifice, with various curves representing different bypass flows\u2014indicating that valve capacity and performance are contingent on bypass flow rather than control flow. This model fits into cavity T-163A and boasts a series 0 capacity of 5 gpm (20 L/min), with factory pressure settings calibrated at 4 gpm (15 L/min). It can withstand a maximum operating pressure of 5000 psi (350 bar) and features a typical response time of 10 ms. The maximum valve leakage at 110 SUS (24 cSt) is rated at 2 in\u00b3/min (30 cc/min) under a pressure of 1000 psi (70 bar). For adjustments, it requires approximately five clockwise turns to increase settings, with specific torque values for installation and adjustment components provided for accurate setup. The model has a weight of .30 lb (.15 kg) and includes a Viton seal kit under cartridge number 990163006 for maintenance purposes.
