The Sun Hydraulics RVBACQV (Material Number: RVBACQV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation. This valve remains closed under normal conditions and opens to the tank port when the inlet pressure reaches its set point, effectively throttling flow to maintain desired pressure levels. It features a vent port that allows for remote control via other pilot or two-way valves. Notably smooth and quiet in operation, this valve is characterized by low-pressure rise relative to flow and moderate response speed. The RVBACQV can handle maximum pressure at port 2, making it suitable for cross-port relief circuits, though spool leakage should be considered in such applications. The minimum setting across all spring ranges is 75 psi (5 bar), but it is not recommended for load-holding applications due to potential spool leakage. Backpressure on the tank port directly affects the valve setting at a 1:1 ratio. To protect against contamination, the main stage orifice is safeguarded, and its floating style construction minimizes risks of internal binding due to excessive installation torque or machining variations. With a capacity of 7.5 gpm (30 L/min) and maximum operating pressure up to 5000 psi (350 bar), this valve offers reliable performance with typical response times around 10 ms. Its design includes features like adjustable settings with up to five clockwise turns and secure installation torque parameters. The RVBACQV model weighs approximately .30 lb (.15 kg) and requires specific installation tools including a hex size of 3/4 inch (19.1 mm). For maintenance or adjustments, an internal hex size of 5/32 inch (4 mm) and locknut hex size of 9/16 inch (15 mm) are needed, ensuring precise control over operational settings.
