The Sun Hydraulics RVIBCCV (Material Number: RVIBCCV) is a versatile three-port normally closed modulating element designed to provide dual functionality when paired with an external orifice. It acts as a bypass compensator, managing priority flow into a circuit while redirecting excess input flow to tank port 2. Additionally, if the inlet pressure at port 1 exceeds the valve setting, it functions as a standard relief valve. This model features a compensating pressure of 90 psi (6 bar) across all ranges. The performance curve illustrates that the system pressure on the X-axis correlates with the pressure differential on the Y-axis created by the valve across the control orifice. The curves depict various bypass flows, indicating that the valve's capacity and performance are primarily determined by bypass flow rather than control flow. This cartridge is configured with EPDM seals suitable for systems utilizing phosphate ester fluids, as exposure to petroleum-based substances can damage these seals. The RVIBCCV fits into cavity T-19A and belongs to Series 4, boasting a capacity of up to 80 gpm (320 L/min). It can operate under maximum pressures of 5000 psi (350 bar) with a typical response time of 10 ms and minimal leakage rates at specified conditions. For installation, the valve requires torque specifications between 350-375 lbf ft (474-508 Nm), and adjustments can be made via an internal hex screw requiring up to five clockwise turns to increase settings. The model weighs approximately 3.10 lb (1.40 kg) and utilizes Viton seal kits for maintenance or replacement needs.
