The Sun Hydraulics RVCBLBN (RVCBLBN) is a three-port normally closed modulating element with relief that provides dual functionality when integrated with an external orifice. This component primarily acts as a bypass compensator, regulating priority flow into a circuit as determined by the external orifice, while any surplus input flow is redirected to tank port 2. Additionally, if the pressure at inlet port 1 exceeds the valve's set threshold, it functions as a standard 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 how system pressure on the X-axis correlates with the pressure differential on the Y-axis that this valve creates across the control orifice. Notably, the valve's capacity and performance are influenced by bypass flow rather than control flow. This model is designed to fit cavity T-11A and belongs to Series 1 with a capacity of up to 10 gpm (40 L/min). It supports a maximum operating pressure of 5000 psi (350 bar) and typically responds within 10 milliseconds. Its maximum leakage rate at 110 SUS (24 cSt) is specified at 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). The adjustment mechanism allows for setting increases through up to five full clockwise turns. Key dimensions include a valve hex size of .78 inches (22.2 mm), installation torque ranging from 30 to 35 lbf\u00b7ft (41 to 47 Nm), an internal hex size of .156 inches (4 mm) for adjustment screws, and a locknut hex size of .5625 inches (15 mm), with locknut torque specifications between 80 to 90 lbf\u00b7in (9 to 10 Nm). The model weighs approximately .40 lb (.20 kg).
