The Sun Hydraulics RBAEOEN (RBAEOEN) is a versatile two-port, pilot-stage, direct-acting relief cartridge designed for precise pressure regulation in hydraulic systems. This normally closed pressure regulating valve opens a flow path from port 1 to port 2 when the inlet pressure at port 1 surpasses the spring force setting. It's engineered to fit into the Sun T-8A two-port cavity, making it an optimal choice for integration with Sun's main stage pilot or vent-to-operate cartridges. This design eliminates separate pilot lines and requires only one cavity for both control and primary functions. The valve supports pressures up to 5000 psi (350 bar) at ports 1 and 2, with backpressure at port 2 directly additive to the pressure setting at port 1. Featuring hardened poppet and seat components, the RBAEOEN ensures consistent operation with low leakage rates and exceptional wear resistance. It incorporates Sun's floating style construction to minimize internal binding risks due to excessive torque or machining variations. The valve accommodates a flow capacity of 2.5 gpm (10 L/min) and maintains factory pressure settings established at a minimum of 30 cc/min. The response time is typically around 2 milliseconds, with a maximum valve leakage of 15 drops/min (1 cc/min) at 110 SUS (24 cSt). For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended; however, exposure to petroleum-based fluids can damage these seals. Installation requires specific torque values: the main stage valve should be installed first followed by the T8A pilot control section. The product includes detailed specifications for installation and adjustment screws, ensuring ease of use in various hydraulic applications where precise pressure control is crucial.
