The Sun Hydraulics RBAAODN (RBAAODN) is a direct-acting, pilot relief cartridge designed to remotely control the pressure setting of other pilot-operated valves. It is specifically engineered for use in load-holding applications, with a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 0.5 gpm (2 L/min). The valve's main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability in various environments. The RBAAODN model incorporates Sun's floating style construction to minimize internal parts binding due to excessive installation torque or cavity/cartridge machining variations. The valve features adjustable settings via W or Y controls, which can be specified with or without a special setting that determines the maximum valve setting. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended, as exposure to petroleum-based fluids can damage these seals. Additionally, the model supports back pressure on the tank port at a 1:1 ratio directly additive to the valve setting. This cartridge valve is suitable for corrosive environments when configured with corrosion-resistant options like external stainless steel components (AP suffix) or zinc-nickel plated components (LH suffix). The RBAAODN has a typical response time of 2 ms and a maximum valve leakage rate of 5 drops/min at 110 SUS (24 cSt). Installation requires specific torque settings and adjustment procedures detailed in its specifications. The product also includes a Viton seal kit for maintenance and compatibility purposes.
