The Sun Hydraulics RVCBKCN (Material Number: RVCBKCN) is a three-port normally closed modulating element with relief, designed to provide dual functionality when used with an external orifice. Primarily, it serves as a bypass compensator that regulates priority flow into a circuit, with any excess input flow being redirected to tank port 2. Additionally, if the pressure at inlet port 1 exceeds the valve setting, the valve functions as a conventional relief valve. The compensating pressure varies across ranges: 45 psi (3 bar) for A range, 30 psi (2 bar) for B range, and 100 psi (7 bar) for C range. The performance curve illustrates system pressure on the X-axis and pressure differential across the control orifice on the Y-axis, dependent on bypass flows rather than control flow. The valve fits a T-11A cavity and has a capacity of 10 gpm (40 L/min). It operates at a maximum pressure of 5000 psi (350 bar), with a typical response time of 10 ms and maximum leakage of 2 in\u00b3/min at 110 SUS (30 cc/min at 70 bar). The factory pressure settings are established at 4 gpm (15 L/min). Adjustments can be made via clockwise turns to increase settings up to a maximum of five turns. Installation requires specific torque values: valve installation torque is between 30-35 lbf ft (41-47 Nm), while locknut torque is set between 80-90 lbf in (9-10 Nm). The model weighs approximately .40 lb (.20 kg) and uses Viton seal kits under part number 990011006.
