The Sun Hydraulics RVIBCBV (RVIBCBV) is a versatile three-port normally closed modulating element with relief capabilities, designed to provide dual functions when paired with an external orifice. This component acts primarily as a bypass compensator, regulating priority flow into a circuit based on the external orifice, while excess input flow is redirected to the tank port 2. Additionally, if pressure at inlet port 1 exceeds the valve's preset level, it functions as a conventional relief valve. The compensating pressure for all ranges stands at 90 psi (6 bar), and its performance is illustrated through curves that map system pressure against the pressure differential across the control orifice. Notably, this valve's capacity and performance are influenced by bypass flow rather than control flow. Cartridges equipped with EPDM seals are specifically intended for systems using phosphate ester fluids; exposure to petroleum-based substances can damage these seals. The RVIBCBV fits into cavity T-19A and belongs to series 4, offering a maximum capacity of 80 gpm (320 L/min) and operating under pressures up to 5000 psi (350 bar). It features a typical response time of 10 ms and maintains minimal leakage at specified conditions. The valve allows adjustment via an internal hex screw, with specific torque settings for installation and locknut adjustments. Weighing in at 3.10 lbs (1.40 kg), this model also includes options for Viton seal kits if needed for alternative fluid compatibility.
