The Sun Hydraulics RVCBLCN (RVCBLCN) is a three-port normally closed modulating element with relief that provides dual functions when paired with an external orifice. This component acts as a bypass compensator, regulating priority flow into a circuit based on the external orifice's specifications, while excess input flow is redirected to tank port 2. When pressure at inlet port 1 exceeds the valve setting, it operates as a standard relief valve. The compensating pressure varies by range: 45 psi (3 bar) for A, 30 psi (2 bar) for B, and 100 psi (7 bar) for C. The valve's performance curve illustrates system pressure on the X axis and the resulting pressure differential across the control orifice on the Y axis, with curves indicating various bypass flows\u2014demonstrating that capacity and performance are determined by bypass flow rather than control flow. Designed to fit cavity T-11A Series 1, this model has a capacity of up to 10 gpm (40 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). Its typical response time is approximately 10 ms, with maximum valve leakage at 110 SUS/24 cSt rated at 2 in\u00b3/min (30 cc/min) at pressures of up to 1000 psi (70 bar). Adjustment is achieved through clockwise turns of up to five and a half turns for increasing settings. Installation requires a valve hex size of .78 inches (22.2 mm) and torque between 30 - 35 lbf ft (41 - 47 Nm). The internal hex size for adjustment screws is .532 inches (4 mm), while locknut hex size is .916 inches (15 mm), requiring torque between 80 - 90 lbf in (9 -10 Nm). This model weighs approximately .40 lb (.20 kg), and it uses Viton seal kits identified by part number 990011006.
