The Sun Hydraulics RBAEYAE (RBAEYAE) is a two-port, pilot-stage, direct-acting relief cartridge designed for precise pressure regulation. This normally closed valve operates by opening a flow path from port 1 to port 2 when the inlet pressure at port 1 surpasses the preset spring force. It utilizes the Sun T8A two-port cavity, making it an optimal choice for integration with Sun's main stage pilot or vent-to-operate cartridges, eliminating the need for separate pilot lines and requiring only one cavity to accommodate both control and primary functions. The valve can handle pressures up to 5000 psi (350 bar) at both ports. The hardened poppet and seat ensure consistent operation with low leakage rates and superior wear characteristics. The RBAEYAE incorporates Sun's floating style construction, minimizing internal part binding due to excessive installation torque or machining variations. It features a factory pressure setting established at 2 in\u00b3/min (30 cc/min) and has a maximum operating pressure of 5000 psi (350 bar) with a typical response time of 2 ms. The maximum valve leakage at 110 SUS (24 cSt) is limited to 15 drops/min (1 cc/min). Installation requires specific torque values: valve installation torque is between 20\u201325 lbf-ft (27\u201333 Nm), while the locknut torque is set between 80\u201390 lbf-in (9\u201310 Nm). For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended; however, exposure to petroleum-based fluids should be avoided as it will damage these seals. With its robust design and reliable performance characteristics, this relief cartridge is suitable for applications requiring quick response and stable pressure regulation without compromising on durability or efficiency.
