The Sun Hydraulics RVIBCAV (Material Number: RVIBCAV) is a three-port, normally closed modulating element with relief capabilities. This versatile component serves dual functions when paired with an external orifice. The mainstage acts as a bypass compensator, controlling priority flow into a circuit as dictated by the external orifice, while excess input flow is redirected to tank port 2. Additionally, if pressure at inlet port 1 exceeds the valve's setting, it functions as a standard relief valve. The compensating pressure for all ranges is set at 90 psi (6 bar). The performance curve indicates system pressure on the X-axis and the pressure differential across the control orifice on the Y-axis, with bypass flows determining capacity and performance. This cartridge is optimized for systems using phosphate ester fluids due to its EPDM seals; exposure to petroleum-based substances will compromise seal integrity. It features a T-19A cavity and series 4 capacity of up to 80 gpm (320 L/min), supporting a maximum operating pressure of 5000 psi (350 bar). Typical response time is approximately 10 ms, and maximum valve leakage at 110 SUS (24 cSt) is rated at 5 in\u00b3/min (80 cc/min) under pressures of up to 1000 psi (70 bar). Adjustments can be made via an internal hex screw with specific torque requirements for installation and locknut adjustments. The model weighs approximately 3.10 lb (1.40 kg), and Viton seal kits are available under part number 990019006.
