The Sun Hydraulics RVEAOSV (RVEAOSV) 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 threshold, effectively throttling flow to maintain regulated pressure. It features a vent port that enables remote control by other pilot or 2-way valves. Known for its accuracy and low-pressure rise versus flow characteristics, the RVEAOSV provides smooth and quiet operation with moderate speed. It is capable of handling maximum pressure at port 2 and is suitable for use in cross-port relief circuits, though spool leakage should be considered in such applications. The main stage orifice is protected by a 150-micron stainless steel screen, ensuring durability and reliability. However, this valve is not recommended for load-holding applications due to potential spool leakage. Back pressure on the tank port directly influences the valve setting at a 1:1 ratio. Cartridges with EPDM seals are specifically designed for systems using phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. The valve incorporates Sun's floating style construction to minimize internal binding risks caused by excessive installation torque or machining variations. With a capacity of 30 gpm (120 L/min) and maximum operating pressure of 5000 psi (350 bar), this cartridge features an adjustment range facilitated by a number of clockwise turns to increase settings up to five times. The valve installation requires specific torque settings and comes with Viton seal kits available under part number 990202006. The RVEAOSV model weighs approximately 0.70 lb (0.30 kg), making it a robust yet manageable component for hydraulic systems requiring precise pressure regulation capabilities.
