The Sun Hydraulics RVGBKDN (RVGBKDN) is a three-port normally closed modulating element with relief, designed to perform dual functions when used in conjunction with an external orifice. This valve acts as a bypass compensator, managing priority flow into the circuit as determined by the external orifice, with any excess input flow being diverted 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 across all ranges is maintained at 120 psi (8 bar). The performance curve illustrates system pressure on the X-axis and the pressure differential created by the valve across the control orifice on the Y-axis, with various curves representing different bypass flows. The valve's capacity and performance are dictated by this bypass flow, independent of control flow. The RVGBKDN model fits into cavity T-17A and belongs to Series 3, offering a capacity of up to 40 gpm (160 L/min). It can operate at a maximum pressure of 5000 psi (350 bar) and typically responds within 10 milliseconds. At an oil viscosity of 110 SUS (24 cSt), maximum valve leakage is limited to 4 in\u00b3/min (65 cc/min) at 1000 psi (70 bar). Adjustments can be made with up to 5.5 clockwise turns to increase settings, using a hex size of 5/32 in. for adjustment screws and a locknut hex size of 9/16 in., requiring torque settings between 80-90 lbf.in (9-10 Nm). Weighing approximately 1.60 lb (0.70 kg), it is compatible with Viton seal kits identified by cartridge number: 990017006.
