The Sun Hydraulics RVBBKCN (RVBBKCN) is a three-port normally closed modulating element with relief, designed to provide dual functionality when combined with an external orifice. It acts as a bypass compensator, controlling priority flow into a circuit based on the external orifice while bypassing excess input flow to tank port 2. Additionally, if the pressure at inlet port 1 exceeds the valve setting, it functions as a standard relief valve. This model is engineered to compensate pressure across all ranges at 50 psi (3.5 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. Its capacity and performance are determined by bypass flow rather than control flow. The RVBBKCN features a T-163A cavity and offers a series 0 capacity of up to 5 gpm (20 L/min). It can handle a maximum operating pressure of 5000 psi (350 bar) with typical response times around 10 ms and maximum valve leakage at 110 SUS (24 cSt) of 2 in\u00b3/min (30 cc/min). Adjustment is achieved via clockwise turns to increase settings, with specifics including a valve hex size of 3/4 inch (19.1 mm), installation torque between 20-25 lbf ft (27-33 Nm), an internal hex size for adjustment screws of 5/32 inch (4 mm), and locknut hex size of 9/16 inch (15 mm) requiring torque between 80-90 lbf in (9-10 Nm). The model weighs approximately .30 lb (.15 kg) and utilizes Viton seal kits, specifically cartridge number 990163006.
