The Sun Hydraulics RVCBCBV (RVCBCBV) is a versatile three-port normally closed modulating element designed to provide dual functionality when used with an external orifice. This component acts as a bypass compensator, controlling priority flow into the circuit based on the external orifice specifications, while excess input flow is redirected to tank port 2. Additionally, if the inlet pressure at port 1 exceeds the predefined valve setting, it functions as a standard 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 illustrates system pressure on the X-axis and the pressure differential across the control orifice on the Y-axis, with curves representing various bypass flows. Notably, this valve's capacity and performance are determined by bypass flow rather than control flow. Key specifications include a cavity type of T-11A Series 1 with a capacity of 10 gpm (40 L/min), a maximum operating pressure of 5000 psi (350 bar), and typical response time of 10 ms. Maximum valve leakage is specified at 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). The adjustment mechanism involves up to five clockwise turns to increase setting, with specific hex sizes for various components: valve hex size is .78 in. (22.2 mm), adjustment screw internal hex size is .532 in. (4 mm), and locknut hex size is .916 in. (15 mm). Installation torque ranges from 30-35 lbf ft (41-47 Nm), and locknut torque from 80-90 lbf in. (9-10 Nm). The model weighs .40 lb (.20 kg) and uses a Viton seal kit identified by cartridge number 990011006.
