The Sun Hydraulics RVBBLQN (Material Number: RVBBLQN) is a three-port, normally closed modulating element with relief functionality, designed to provide dual operations when used with an external orifice. Primarily, it acts as a bypass compensator that manages priority flow into a circuit based on the external orifice's parameters. Any input flow exceeding the priority flow is redirected to tank port 2. Additionally, should the pressure at inlet port 1 surpass the valve's preset threshold, it functions as a conventional relief valve. The valve maintains a compensating pressure of 50 psi (3.5 bar) across all ranges. Performance characteristics are depicted through curves where the X-axis represents system pressure and the Y-axis indicates the pressure differential caused by the valve across the control orifice; these curves illustrate various bypass flows (the difference between pump flow and control flow). The valve's capacity and performance are dictated by bypass flow, independent of control flow factors. The RVBBLQN fits a T-163A cavity and offers a series 0 capacity of up to 5 gpm (20 L/min). It can withstand maximum operating pressures of up to 5000 psi (350 bar) and typically responds within 10 milliseconds. The maximum leakage rate at 110 SUS (24 cSt) is approximately 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). Users can adjust settings with up to five clockwise turns, requiring specific torque values for installation and adjustment components: valve installation torque ranges from 20 to 25 lbf\u00b7ft (27 to 33 Nm), while locknut torque requires between 80 and 90 lbf\u00b7in (9 to 10 Nm). The model weighs approximately .30 lb (.15 kg) and uses Viton seal kits for cartridge sealing 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.
