The Sun Hydraulics RVBBLBN (RVBBLBN) is a versatile three-port, normally closed modulating element with relief capabilities. This component serves dual functions when paired with an external orifice. The main stage acts as a bypass compensator that prioritizes flow into the circuit according to the external orifice setting, while any excess input flow is redirected to tank port 2. In cases where the inlet port 1 pressure exceeds the valve setting, it operates as a standard relief valve. With a compensating pressure of 50 psi (3.5 bar) across all ranges, this valve's performance is illustrated through its specific performance curve, highlighting system pressure against the pressure differential created across the control orifice. This model has a capacity of 5 gpm (20 L/min) and a maximum operating pressure of 5000 psi (350 bar). It features a typical response time of 10 milliseconds and minimal leakage at maximum levels, ensuring efficient operation under various conditions. Installation requires specific torque settings, with an adjustment screw internal hex size of 5/32 in. (4 mm) and locknut torque between 80-90 lbf in. (9-10 Nm). The RVBBLBN model weighs approximately .30 lb (.15 kg) and uses a Viton seal kit identified by cartridge number 990163006 for maintenance purposes.
