The Sun Hydraulics RVBBKNV (RVBBKNV) is a sophisticated three-port normally closed modulating element with relief capabilities, designed to perform dual functions when used alongside an external orifice. This component acts primarily as a bypass compensator, regulating priority flow into the circuit as dictated by the external orifice, while any excess input flow is redirected to tank port 2. Additionally, if the pressure at inlet port 1 exceeds the valve's set threshold, it operates as a standard relief valve. It features a compensating pressure of 50 psi (3.5 bar) across all ranges and is characterized by its performance curve where system pressure (X-axis) influences the pressure differential across the control orifice (Y-axis). The valve's capacity and performance are governed by bypass flow rather than control flow. It supports a cavity T-163A series with a capacity of 5 gpm (20 L/min), and it can withstand a maximum operating pressure of 5000 psi (350 bar). The typical response time for this model is approximately 10 ms, and it maintains minimal valve leakage at 110 SUS (24 cSt), specifically 2 in\u00b3/min (30 cc/min) at 1000 psi (70 bar). Adjustments to increase settings require up to five clockwise turns, with specific torque requirements for installation and locknut adjustments. Weighing .30 lb (.15 kg), this model also includes options for Viton seal kits under cartridge specifications.
