The Sun Hydraulics RVBBCBN (Material Number: RVBBCBN) is a three-port normally closed modulating element with relief, designed to perform dual functions when used with an external orifice. It acts as a bypass compensator to manage priority flow into the circuit, defined by the external orifice, while diverting any excess input flow to the tank port 2. Additionally, if pressure at inlet port 1 exceeds the valve's setting, it functions as a standard relief valve. The compensating pressure across all ranges is maintained at 50 psi (3.5 bar). The performance curve illustrates system pressure on the X-axis and the pressure differential created across the control orifice on the Y-axis, with curves depicting various bypass flows. This valve's capacity and performance are contingent upon bypass flow; control flow does not influence these factors. The valve fits into cavity T-163A and has a series 0 capacity of 5 gpm (20 L/min). It can operate at a maximum pressure of 5000 psi (350 bar) with a typical response time of 10 ms. The maximum valve leakage at 110 SUS (24 cSt) is recorded at 2 in\u00b3/min (30 cc/min) at 1000 psi (70 bar). The adjustment requires up to five clockwise turns to increase settings, and installation demands a torque of 20\u201325 lbf ft (27\u201333 Nm). The internal hex size for adjustment screws is ^5/32 in. (4 mm), while locknut hex size is ^9/16 in. (15 mm), requiring a torque of 80\u201390 lbf in. (9\u201310 Nm). The model weighs .30 lb (.15 kg) and utilizes Viton seal kits for cartridges, specifically part number 990163006.
