The Sun Hydraulics RVIBKCV (RVIBKCV) is a three-port normally closed modulating element with relief functionality, designed to provide dual functions when paired with an external orifice. It acts as a bypass compensator, managing priority flow within a circuit based on the external orifice, while excess input flow is redirected to tank port 2. Should the pressure at inlet port 1 exceed the valve's set point, it functions as a conventional relief valve. The compensating pressure for all ranges is set at 90 psi (6 bar). The performance curve illustrates system pressure on the X-axis and the pressure differential across the control orifice on the Y-axis, with curves representing various bypass flows. This valve's capacity and performance are influenced by bypass flow rather than control flow. It is essential to note that cartridges equipped with EPDM seals are intended for systems utilizing phosphate ester fluids; contact with petroleum-based fluids will damage these seals. The RVIBKCV fits into cavity T-19A and belongs to Series 4, offering a capacity of up to 80 gpm (320 L/min). Its maximum operating pressure reaches 5000 psi (350 bar), with a typical response time of 10 ms. Maximum valve leakage at 110 SUS (24 cSt) is rated at 5 in\u00b3/min (80 cc/min) under conditions of 1000 psi (70 bar). For adjustments, it requires up to five clockwise turns to increase settings, and installation torque ranges between 350 - 375 lbf\u00b7ft (474 - 508 Nm). Weighing approximately 3.10 lb (1.40 kg), this model can be sealed using Viton seal kits like CartridgeViton: 990019006 for optimal performance in compatible applications.
