The Sun Hydraulics RVCBKCV (RVCBKCV) is a versatile three-port, normally closed modulating element with relief capabilities. This component is designed to provide dual functions when used with an external orifice. Primarily, it acts as a bypass compensator, regulating priority flow into the circuit based on the external orifice's specifications. Any input flow exceeding this priority flow is redirected to tank port 2. Additionally, if the pressure at inlet port 1 surpasses the valve's set threshold, it functions as a standard relief valve. 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 of this valve is illustrated through its performance curve, where system pressure is plotted against the pressure differential created across the control orifice. The curves indicate various bypass flows which are determined by subtracting control flow from pump flow; notably, control flow does not influence capacity and performance. Key specifications include a cavity T-11A series 1 capacity of 10 gpm (40 L/min), maximum operating pressure of 5000 psi (350 bar), and typical response time of 10 ms. The valve has a maximum leakage rate of 2 in\u00b3/min at 110 SUS (24 cSt) and can be adjusted by turning clockwise up to five turns to increase settings. Installation requires specific torque values: valve hex size of .78 in. (22.2 mm), installation torque between 30-35 lbf ft (41-47 Nm), adjustment screw internal hex size of .532 in. (4 mm), locknut hex size of .916 in. (15 mm), and locknut torque between 80-90 lbf in. (9-10 Nm). The model weighs approximately .40 lb (.20 kg) and utilizes a Viton seal kit with cartridge number 990011006 for optimal performance and durability in hydraulic systems.
