The Sun Hydraulics RVBACQN (RVBACQN) is a ventable, pilot-operated, balanced piston relief cartridge designed to function as a normally closed pressure regulating valve. This model is engineered to open at the tank port when the inlet pressure reaches the pre-set level, effectively throttling flow to maintain consistent pressure. It features a vent port that allows for remote control through other pilot or two-way valves, making it adaptable for various hydraulic applications. The RVBACQN is known for its accuracy, low pressure rise versus flow characteristics, and smooth operation with moderate response speed. This valve is capable of handling maximum pressures at port 2 and can be used in cross-port relief circuits with considerations for spool leakage. However, it is not suitable for load-holding applications due to potential leakage issues. The minimum setting for this model is 75 psi (5 bar), and any backpressure on the tank port directly affects the valve setting in a 1:1 ratio. The main stage orifice's design protects against contamination and incorporates Sun's floating style construction to minimize risks of internal binding due to excessive installation torque or machining variations. The RVBACQN fits into cavity T-163A and offers a series 0 capacity of 7.5 gpm (30 L/min). It operates under a maximum pressure of 5000 psi (350 bar) with control pilot flow ranging from 7-10 in\u00b3/min (0.11-0.16 L/min). Typical response time is around 10 ms, ensuring efficient performance in dynamic systems. With a maximum valve leakage at standard conditions being minimal, this model provides reliable performance across various settings. Installation specifications include a valve hex size of 3/4 inch (19.1 mm) and an adjustment screw internal hex size of 5/32 inch (4 mm). The model weighs approximately .30 lb (.15 kg) and uses Viton seal kits for enhanced durability.

Ventable, pilot-operated, balanced piston relief cartridges are normally closed pressure regulating valves. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to regulate the pressure. They provide a vent port (port 3) that connects between the main piston and pilot stage to provide for remote control by other pilot or 2-way valves. These valves are accurate, have low pressure rise vs. flow, they are smooth and quiet, and are moderately fast.
- A remote pilot relief on port 3 (vent) will control the valve below its own setting.
- Will accept maximum pressure at port 2; suitable for use in cross port relief circuits. If used in cross port relief circuits, consider spool leakage.
- Minimum setting is 75 psi (5 bar) for all spring ranges.
- Not suitable for use in load holding applications due to spool leakage.
- Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.
- The main stage orifice is protected against contamination.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
