The Sun Hydraulics RVBBKWV (RVBBKWV) is a versatile three-port normally closed modulating element with relief capabilities, designed to perform dual functions when used with an external orifice. This component acts as a bypass compensator, managing priority flow into a circuit as defined by the external orifice, while any excess input flow is diverted to the tank port 2. Additionally, if the pressure at inlet port 1 exceeds the valve's predetermined setting, it operates as a conventional relief valve. The compensating pressure for all ranges is set at 50 psi (3.5 bar), and its performance is illustrated through a curve where the X-axis represents system pressure and the Y-axis denotes the pressure differential across the control orifice. The valve\u2019s capacity and performance are contingent upon bypass flow rather than control flow. This model features a cavity T-163A series with a capacity of 5 gpm (20 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). It exhibits a typical response time of 10 ms and allows for maximum valve leakage at 110 SUS (24 cSt) of 2 in\u00b3/min (1000 psi) or 30 cc/min (70 bar). Adjustments can be made with up to 5.5 clockwise turns to increase settings, utilizing an internal hex size of 5/32 in. (4 mm) for adjustment screws and requiring locknut torque between 80 - 90 lbf-in. (9 - 10 Nm). The valve has an installation torque range of 20 - 25 lbf-ft (27 - 33 Nm), with an overall weight of .30 lb (.15 kg). It includes a Viton seal kit cartridge identified by part number 990163006.
