The Sun Hydraulics RVCBLWN (RVCBLWN) is a versatile three-port, normally closed modulating element with relief capabilities. Designed to provide dual functions when paired with an external orifice, this component acts as a bypass compensator. It regulates a priority flow into the hydraulic circuit determined by the external orifice, while any input flow exceeding this priority is diverted to tank port 2. Additionally, when the inlet port 1 pressure reaches the valve's preset level, it functions as a typical relief valve. The compensating pressure varies across different 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 of this valve illustrates system pressure on the X-axis and the pressure differential across the control orifice on the Y-axis. These curves indicate various bypass flows, which are calculated by subtracting control flow from pump flow; notably, control flow does not impact capacity and performance. This model fits within cavity T-11A series 1 and boasts a capacity of up to 10 gpm (40 L/min). It can operate at a maximum pressure of 5000 psi (350 bar), with a typical response time of just 10 milliseconds. Additional specifications include maximum valve leakage at 110 SUS (24 cSt) of 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). The adjustment mechanism allows for up to five clockwise turns to increase settings. The valve hex size is .78 inches (22.2 mm), requiring an installation torque between 30-35 lbf ft (41-47 Nm). The internal hex size for adjustment screws is 5/32 inches (4 mm), while the locknut hex size is 9/16 inches (15 mm), with a locknut torque range of 80-90 lbf in (9-10 Nm). This model weighs .40 lb (.20 kg) and uses Viton seal kits identified by cartridge number: 990011006.
