The Sun Hydraulics RVCBKBN (Material Number: RVCBKBN) is a three-port normally closed modulating element with relief capability, designed to provide dual functionality when used in conjunction with an external orifice. The mainstage functions as a bypass compensator, controlling priority flow into the circuit as dictated by the external orifice. Any input flow exceeding this priority flow is directed to tank port 2. Additionally, if the pressure at inlet port 1 exceeds the valve setting, it operates like a standard relief valve. The compensating pressure varies across different ranges: 45 psi (3 bar) for the A range, 30 psi (2 bar) for the B range, and 100 psi (7 bar) for the C range. Performance is illustrated through a curve where system pressure is plotted on the X-axis and pressure differential across the control orifice on the Y-axis. This valve's capacity and performance are influenced by bypass flow; control flow remains unaffected. It features a cavity size of T-11A, Series 1, with a capacity of 10 gpm (40 L/min) and can handle maximum operating pressures up to 5000 psi (350 bar). Typical response time is around 10 ms with minimal leakage rates at specified conditions. Installation specifics include a valve hex size of .78 inches (22.2 mm), installation torque ranging from 30 to 35 lbf ft (41 to 47 Nm), adjustment screw internal hex size of .532 inches (4 mm), locknut hex size of .916 inches (15 mm), and locknut torque between 80 to 90 lbf in (9 to 10 Nm). The model weighs approximately .40 lb (.20 kg) and utilizes Viton seals for its cartridge seal kit.
