The Sun Hydraulics RVBBCNV (Material Number: RVBBCNV) is a three-port, normally closed modulating element with relief, designed to provide dual functions when used with an external orifice. This versatile hydraulic component functions primarily as a bypass compensator, which regulates a priority flow into the circuit, determined 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 setting, it operates as a conventional relief valve. The compensating pressure for all ranges is set at 50 psi (3.5 bar). The performance curve of this component is characterized by system pressure on the X-axis and the pressure differential across the control orifice on the Y-axis, with various curves illustrating different bypass flows. Notably, the valve's capacity and performance are influenced by bypass flow rather than control flow. The Sun Hydraulics RVBBCNV has a cavity size of T-163A Series 0 and a capacity of 5 gpm (20 L/min). It can handle a maximum operating pressure of up to 5000 psi (350 bar) and exhibits a typical response time of approximately 10 ms. Under conditions of maximum valve leakage at 110 SUS (24 cSt), it leaks about 2 in\u00b3/min (30 cc/min) at 1000 psi (70 bar). The adjustment for increasing settings requires approximately five clockwise turns, with specific torque requirements for installation and locknut adjustments provided for precision assembly and maintenance. The model weighs about .30 lb (.15 kg) and uses Viton seal kits for reliable sealing performance.
