The Sun Hydraulics RVCBCAV (RVCBCAV) is a three-port normally closed modulating element with relief capabilities, designed to manage specific hydraulic flow and pressure requirements. This valve serves dual functions when paired with an external orifice: it acts as a bypass compensator controlling priority flow into the circuit, while any excess input flow is redirected to tank port 2. Additionally, if the inlet port 1 pressure exceeds the valve's setting, it functions as a conventional 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 indicates that the system pressure on the X-axis and pressure differential on the Y-axis are influenced by bypass flows, independent of control flow. With a capacity of 10 gpm (40 L/min) and maximum operating pressure reaching up to 5000 psi (350 bar), this valve is built for demanding applications. It features a rapid response time of approximately 10 ms and maintains minimal leakage at specified conditions. Installation parameters include a valve hex size of .78 in. (22.2 mm) and an installation torque between 30 to 35 lbf ft (41 to 47 Nm). Adjustments can be made using an internal hex screw size of 5/32 in. (4 mm), with locknut adjustments requiring a torque of 80 to 90 lbf in. (9 to 10 Nm). Weighing .40 lb (.20 kg), this component is also equipped with Viton seals for enhanced durability and reliability in various hydraulic systems.
