The Sun Hydraulics RVCAOGN (Material Number: RVCAOGN) is a ventable, pilot-operated, balanced piston relief cartridge designed for pressure regulation in hydraulic systems. This normally closed valve 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 for remote control by other pilot or 2-way valves, enabling precise and smooth operation with low pressure rise versus flow. The valve's main stage orifice is safeguarded by a 150-micron stainless steel screen, enhancing durability and performance reliability. This relief cartridge is suitable for applications where maximum pressure at port 2 is needed, such as in cross-port relief circuits; however, users should consider potential spool leakage in these scenarios. It is not recommended for load-holding applications due to this leakage characteristic. The valve setting directly correlates with back pressure on the tank port at a 1:1 ratio, allowing for straightforward adjustments. The RVCAOGN model incorporates Sun's floating style construction to reduce the risk of internal binding from installation torque or machining variations. It accommodates systems with phosphate ester fluids when equipped with EPDM seals but should not be exposed to petroleum-based substances as they may cause seal damage. Key specifications include a capacity of 15 gpm (60 L/min), maximum operating pressure of 5000 psi (350 bar), and typical response time of 10 ms. The adjustment mechanism involves up to five clockwise turns to increase settings, ensuring ease of use and adaptability in various hydraulic configurations. With its robust design and efficient control capabilities, this cartridge offers reliable performance across diverse hydraulic applications.
