The Sun Hydraulics RVBBCWN (Material Number: RVBBCWN) is a three-port, normally closed modulating element with relief functionality, designed to provide dual operations when paired with an external orifice. This component serves as a bypass compensator, controlling priority flow into a hydraulic circuit as dictated by the external orifice. Any input flow exceeding the priority flow is redirected to the tank via port 2. Additionally, if the pressure at inlet port 1 escalates to the valve's predetermined setting, it acts as a conventional relief valve. The compensating pressure across all ranges is maintained at 50 psi (3.5 bar). The performance curve of this valve illustrates system pressure on the X-axis and the pressure differential across the control orifice on the Y-axis, with curves representing various bypass flows\u2014defined as pump flow minus control flow\u2014where capacity and performance are contingent upon bypass flow rather than control flow. The valve fits within cavity T-163A and offers a series 0 capacity of 5 gpm (20 L/min). It operates under a maximum pressure of 5000 psi (350 bar) with a typical response time of 10 ms and maximum leakage at 110 SUS (24 cSt) of 2 in\u00b3/min (30 cc/min) at 1000 psi (70 bar). The adjustment for increasing settings requires approximately five clockwise turns, with installation torque specified between 20 to 25 lbf ft (27 to 33 Nm). The internal hex size for adjustment screws is ^5\u204432 in. (4 mm), while the locknut hex size is ^9\u204416 in. (15 mm), requiring torque between 80 to 90 lbf in. (9 to 10 Nm). This model weighs approximately .30 lb (.15 kg) and utilizes Viton cartridge seal kits under part number 990163006 for maintenance or replacement needs.

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.
