The Sun Hydraulics RVBBKBN (Material Number: RVBBKBN) is a versatile three-port normally closed modulating element with relief capabilities, designed to offer dual functions when used in conjunction with an external orifice. This component serves as a bypass compensator, managing priority flow into the circuit as defined by the external orifice. Any input flow exceeding this priority flow is efficiently redirected to tank port 2. Additionally, if the pressure at inlet port 1 surpasses the valve's preset threshold, it functions as a conventional 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 by the valve across the control orifice on the Y-axis, with curves representing various bypass flows\u2014where pump flow minus control flow determines capacity and performance. This model accommodates a capacity of 5 gpm (20 L/min) within cavity T-163A Series 0 and operates at a maximum pressure of 5000 psi (350 bar). It boasts a typical response time of 10 ms and has minimal leakage rates under specified conditions. The adjustment mechanism involves up to 5.5 clockwise turns to increase settings, with specific torque requirements for installation and adjustment components. Weighing in at .30 lb (.15 kg), this model uses Viton cartridge seals for enhanced durability and performance under various conditions.

Three-port normally closed modulating elements with relief provide two functions when combined with an external orifice. The mainstage is a bypass compensator that controls a priority flow into the circuit, determined by the external orifice. Input flow in excess of the priority flow is bypassed to tank (port 2). If the inlet (port 1) pressure rises to the valve setting, the valve operates as a normal relief valve.

  • Compensating pressure for all ranges is 50 psi (3,5 bar).
  • Explanation of the performance curve: The X axis is system pressure. The Y axis shows the pressure differential that the valve creates across the control orifice. The curves represent various bypass flows (pump flow minus control flow). The capacity and performance of this valve is determined by the bypass flow, control flow is not a factor.
