The Sun Hydraulics RVBAKBN (RVBAKBN) is a ventable, pilot-operated, balanced piston relief cartridge designed to regulate pressure by throttling flow when the inlet pressure reaches the valve setting. It features a vent port that allows for remote control by other pilot or 2-way valves, enhancing its versatility. This valve is known for its accuracy, low pressure rise versus flow, smooth operation, and moderate response speed. It is particularly suitable for applications requiring maximum pressure at port 2 and can be used in cross-port relief circuits, although spool leakage should be considered in such scenarios. The valve has a minimum setting of 75 psi (5 bar) across all spring ranges but is not recommended for load holding applications due to potential spool leakage. The RVBAKBN can handle back pressure on tank port 2 at a 1:1 ratio to the valve setting and features a main stage orifice protected against contamination. Its construction minimizes internal binding risks due to installation torque or machining variations. The valve fits into Cavity T-163A and has a capacity of 7.5 gpm (30 L/min), with factory pressure settings established at 4 gpm (15 L/min). It operates under a maximum pressure of 5000 psi (350 bar) with control pilot flow between 7-10 in\u00b3/min (0.11-0.16 L/min). Typical response time is around 10 ms with maximum leakage at specified conditions being 2 in\u00b3/min (30 cc/min). The adjustment requires up to five clockwise turns to increase the setting, and it includes specific hex sizes for adjustments and installation torque requirements. The model weighs approximately .30 lb (.15 kg) and uses Viton seal kits for maintenance purposes.
