The Sun Hydraulics RVIBLAV (RVIBLAV) is a versatile three-port normally closed modulating element with relief functionality, designed to provide dual operations when paired with an external orifice. This component primarily acts as a bypass compensator, regulating priority flow into the system circuit as defined by the external orifice, while excess input flow is redirected to tank port 2. Additionally, it serves as a standard relief valve if the pressure at inlet port 1 exceeds the valve's preset threshold. The compensating pressure for all ranges is established at 90 psi (6 bar). The performance of this valve is depicted through curves showing the relationship between system pressure and the pressure differential across the control orifice, with capacity determined by bypass flow rather than control flow. Notably, cartridges with EPDM seals are suitable for systems utilizing phosphate ester fluids and should avoid contact with petroleum-based substances to prevent seal damage. The RVIBLAV model fits into Cavity T-19A and is part of Series 4, offering a capacity of up to 80 gpm (320 L/min). It operates under a maximum pressure of 5000 psi (350 bar) and typically responds within 10 milliseconds. Valve leakage is minimal at specific conditions, and adjustments can be made via an internal hex screw. Installation requires specific torque settings for optimal performance. Weighing approximately 3.10 lb (1.40 kg), this model also supports Viton seal kits for maintenance needs.
