The Sun Hydraulics RVBBCWV (Material Number: RVBBCWV) is a three-port normally closed modulating element with relief, designed to provide dual functionality when used alongside an external orifice. This component acts as a bypass compensator, regulating priority flow into the circuit as defined by the external orifice. Any input flow exceeding this priority flow is redirected to tank port 2. Additionally, if pressure at inlet port 1 exceeds the valve setting, it functions as a standard relief valve. The compensating pressure for all ranges is set at 50 psi (3.5 bar). The performance curve illustrates system pressure on the X-axis against the pressure differential across the control orifice on the Y-axis, with various curves representing different bypass flows (pump flow minus control flow). The valve's capacity and performance are dictated by the bypass flow, independent of control flow. The valve fits into Cavity T-163A Series 0 and has a capacity of 5 gpm (20 L/min). It can handle a maximum operating pressure of up to 5000 psi (350 bar) and typically responds within 10 ms. Under conditions of 110 SUS (24 cSt), its maximum leakage rate is 2 in\u00b3/min (30 cc/min) at 1000 psi (70 bar). Adjustments to increase settings can be made with up to 5.5 clockwise turns, requiring an installation torque between 20-25 lbf ft (27-33 Nm). The valve features a hex size of .34 in. (19.1 mm) and weighs approximately .30 lb (.15 kg). For maintenance, it uses Viton seal kits identified by cartridge number 990163006.
