The Sun Hydraulics RVEAONN (RVEAONN) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation. These normally closed pressure regulating valves open to the tank port when the inlet pressure reaches the valve setting, throttling flow to maintain desired pressure levels. They feature a vent port that allows for remote control via other pilot or 2-way valves. Known for their accuracy and smooth operation, these valves exhibit low pressure rise relative to flow and are moderately fast in response. A key feature is their ability to accept maximum pressure at port 2, making them suitable for cross-port relief circuits; however, spool leakage should be considered in such applications. The design incorporates a main stage orifice shielded by a 150-micron stainless steel screen, ensuring durability and reliability. Notably, these cartridges are not recommended for load-holding applications due to potential spool leakage. The valve setting is directly influenced by back pressure on the tank port at a 1:1 ratio. Cartridges with EPDM seals are intended for systems utilizing phosphate ester fluids; exposure to petroleum-based substances could harm the seals. Sun Hydraulics employs a floating style construction in this model to minimize internal binding risks caused by excessive installation torque or machining variations. The RVEAONN model supports a capacity of 30 gpm (120 L/min) with maximum operating pressures up to 5000 psi (350 bar). It features an adjustment screw with internal hex size specifications and accommodates specific torque requirements during installation. With its robust design and reliable performance characteristics, this cartridge valve is suitable for various hydraulic applications requiring precise pressure control.
