The Sun Hydraulics RVBBLCN (Material Number: RVBBLCN) is a versatile three-port normally closed modulating element with relief functionality, designed to provide dual operations when paired with an external orifice. Its primary role as a bypass compensator allows it to regulate priority flow into a circuit, dictated by the external orifice, while excess input flow is diverted to tank port 2. Additionally, the valve acts as a standard relief valve if the pressure at inlet port 1 reaches the valve's set limit. The compensating pressure across all ranges stands at 50 psi (3.5 bar), and the performance curve illustrates system pressure against the pressure differential created across the control orifice, emphasizing that its capacity and efficacy are determined by bypass flow rather than control flow. This model features a cavity type T-163A and operates with a maximum capacity of 5 gpm (20 L/min). It can handle pressures up to 5000 psi (350 bar) and exhibits rapid response times typically around 10 ms. Leakage rates are minimal, with maximum valve leakage at 110 SUS (24 cSt) being 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). Adjustments for increasing settings require approximately five clockwise turns, with specific torque requirements for installation and adjustments: valve installation torque ranges from 20 to 25 lbf ft (27 to 33 Nm), while locknut torque is between 80 to 90 lbf in (9 to 10 Nm). This model weighs approximately .30 lb (.15 kg) and utilizes a Viton seal kit identified by cartridge number: 990163006.
