The Sun Hydraulics RVIBCDN (RVIBCDN) is a versatile three-port normally closed modulating element with relief, designed to perform dual functions when paired with an external orifice. Acting as a bypass compensator, this mainstage component regulates priority flow within a circuit based on the external orifice's determination. Any input flow surpassing the priority flow is redirected to the tank port 2. Additionally, should the inlet port 1 pressure exceed the valve's setting, it transitions to operate as a conventional relief valve. The valve features a compensating pressure of 90 psi (6 bar) across all ranges. Its performance curve illustrates system pressure on the X-axis and the pressure differential across the control orifice on the Y-axis, with curves representing various bypass flows where capacity and performance are dictated by bypass flow rather than control flow. Configured with EPDM seals, this cartridge is suitable for systems utilizing phosphate ester fluids; however, exposure to petroleum-based fluids can damage these seals. It fits into Cavity T-19A and belongs to Series 4, offering a capacity of up to 80 gpm (320 L/min). The factory pressure settings are established at 4 gpm (15 L/min), while it can handle a maximum operating pressure of 5000 psi (350 bar). Typical response time is around 10 ms, and maximum valve leakage at 110 SUS (24 cSt) is limited to 5 in\u00b3/min (80 cc/min) at 1000 psi (70 bar). The adjustment requires approximately five clockwise turns to increase setting, with specific torque requirements for installation and adjustment components ensuring secure placement and operation. The model weighs approximately 3.10 lb (1.40 kg), and for maintenance or replacement purposes, it uses Viton seal kit number 990019006.
