The Sun Hydraulics RVCBCDV (RVCBCDV) is a three-port normally closed modulating element with relief capabilities, designed to provide dual functions when used with an external orifice. This versatile component operates primarily as a bypass compensator, controlling priority flow into a circuit as determined by the external orifice. Any input flow exceeding the priority flow is efficiently bypassed to tank port 2. Additionally, if the pressure at inlet port 1 surpasses the valve's set point, it functions as a standard relief valve. The compensating pressure varies across different ranges: 45 psi (3 bar) for the A range, 30 psi (2 bar) for the B range, and 100 psi (7 bar) for the C range. The performance curve explanation highlights that system pressure is plotted on the X-axis while the Y-axis represents the pressure differential created across the control orifice. These curves indicate various bypass flows\u2014calculated as pump flow minus control flow\u2014demonstrating that valve capacity and performance are determined by bypass flow alone, irrespective of control flow. The RVCBCDV features a T-11A cavity and Series 1 capacity of up to 10 gpm (40 L/min), with factory pressure settings established at 4 gpm (15 L/min). It supports a maximum operating pressure of 5000 psi (350 bar) and typical response time of just 10 ms. Maximum valve leakage at 110 SUS (24 cSt) is limited to 2 in\u00b3/min (30 cc/min) at 1000 psi (70 bar). Installation and adjustment specifics include a valve hex size of .78 in. (22.2 mm), installation torque between 30\u201335 lbf ft (41\u201347 Nm), adjustment screw internal hex size of .532 in. (4 mm), locknut hex size of .916 in. (15 mm), and locknut torque ranging from 80\u201390 lbf in. (9\u201310 Nm). The model weighs approximately .40 lb (.20 kg) and utilizes Viton seal kits for optimal performance and durability.
