The Sun Hydraulics RVGBKBV (RVGBKBV) is a three-port normally closed modulating element with relief, designed to provide dual functionalities when paired with an external orifice. This valve acts as a bypass compensator, controlling priority flow into the circuit as dictated by the external orifice, while excess input flow is redirected to tank port 2. Additionally, if pressure at inlet port 1 exceeds the valve's setting, it functions as a standard relief valve. The compensating pressure across all ranges is set at 120 psi (8 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. The valve's capacity and performance are determined by bypass flow rather than control flow. It features a T-17A cavity, series 3 capacity of 40 gpm (160 L/min), and can handle a maximum operating pressure of up to 5000 psi (350 bar). Typical response time is around 10 ms, and maximum leakage at 110 SUS (24 cSt) is specified at 4 in\u00b3/min at 1000 psi (65 cc/min at 70 bar). Adjustment for increasing settings requires approximately five clockwise turns. The valve's hex size measures 1\u00bc inches (31.8 mm), with installation torque between 150\u2013160 lbf ft (203\u2013217 Nm). The internal hex size for adjustment screws is ^5/32 inch (4 mm), while the locknut hex size is ^9/16 inch (15 mm) with a torque range of 80\u201390 lbf in (9\u201310 Nm). Weighing approximately 1.60 lb (0.70 kg), it comes equipped with Viton cartridge seals part number: 990017006 for optimal performance in hydraulic systems.
