The Sun Hydraulics RVIBCDV (RVIBCDV) is a three-port, normally closed modulating element with relief that provides dual functions when paired with an external orifice. This component operates as a bypass compensator, managing priority flow into the circuit as dictated by the external orifice, while excess input flow is directed to tank port 2. Additionally, if the pressure at inlet port 1 surpasses the valve setting, it functions as a conventional relief valve. The compensating pressure across all ranges is maintained at 90 psi (6 bar). The performance curve illustrates system pressure on the X-axis and the pressure differential created across the control orifice on the Y-axis, with curves representing various bypass flows. Notably, valve capacity and performance are influenced by bypass flow rather than control flow. This valve is suitable for systems utilizing phosphate ester fluids when equipped with EPDM seals; however, exposure to petroleum-based substances can damage these seals. It features a cavity T-19A series 4 configuration and supports a capacity of up to 80 gpm (320 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), with a typical response time of 10 ms and maximum leakage of 5 in/min at 110 SUS (24 cSt) under 1000 psi (70 bar). Adjustment for increasing settings requires approximately five clockwise turns. Installation specifications include a valve hex size of 1-5/8 inches (41.3 mm) and torque requirements between 350 to 375 lbf-ft (474 to 508 Nm). The internal hex size for adjustment screws is set at 5/32 inches (4 mm), while locknut torque ranges from 80 to 90 lbf-in (9 to 10 Nm). The model's weight stands at approximately 3.10 lb (1.40 kg), and it utilizes Viton seal kits for enhanced durability.
