The Sun Hydraulics RVBBCCV (RVBBCCV) is a versatile three-port normally closed modulating element with relief that combines two essential functions when used with an external orifice. Primarily, it serves as a bypass compensator, managing priority flow into the circuit as determined by the external orifice while redirecting excess flow to tank port 2. Additionally, when the inlet port 1 pressure reaches the valve's preset level, it functions as a standard relief valve. The valve's compensating pressure across all ranges is set at 50 psi (3.5 bar). Its performance is illustrated by a curve where the X-axis represents system pressure and the Y-axis indicates the pressure differential created across the control orifice. The curves depict various bypass flows, which are calculated as pump flow minus control flow, highlighting that the valve's capacity and performance are determined by bypass flow rather than control flow. This model fits into cavity T-163A and offers 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. At 110 SUS (24 cSt), its maximum valve leakage is rated at 2 in\u00b3/min (30 cc/min) under 1000 psi (70 bar). For adjustments, turning clockwise increases settings up to 5.5 turns with specific installation requirements including a valve hex size of .34 in. (19.1 mm) and installation torque of 20 - 25 lbf ft (27 - 33 Nm). The adjustment screw requires an internal hex size of .532 in. (4 mm), while the locknut has a hex size of .916 in. (15 mm) with torque specifications between 80 - 90 lbf in. (9 -10 Nm). The model weighs approximately .30 lb (.15 kg) and utilizes Viton cartridge seals as per seal kit number 990163006.
