The Sun Hydraulics RVCBCBN (Material Number: RVCBCBN) is a three-port normally closed modulating element with relief functionality, designed to perform dual roles when paired with an external orifice. This component operates as a bypass compensator, regulating priority flow into a circuit based on the external orifice while diverting any excess flow to tank port 2. Additionally, it functions as a standard relief valve if the pressure at inlet port 1 exceeds the valve's preset threshold. The compensating pressure varies across different ranges: 45 psi (3 bar) for range A, 30 psi (2 bar) for range B, and 100 psi (7 bar) for range C. The performance curve of this valve illustrates the relationship between system pressure and the pressure differential created across the control orifice, with various curves corresponding to different bypass flows. Key specifications include a cavity size of T-11A and Series 1 capacity handling up to 10 gpm (40 L/min). The factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). The typical response time is approximately 10 milliseconds, while maximum valve leakage at 110 SUS (24 cSt) is measured at 2 in\u00b3/min (30 cc/min) at pressures up to 1000 psi (70 bar). Adjustment features include up to five clockwise turns to increase settings, with specific torque requirements for installation and adjustments. The model weighs approximately .40 lb (.20 kg), and it utilizes Viton seal kits for reliable operation in hydraulic systems.
