The Sun Hydraulics RBAAJEN (RBAAJEN) is a direct-acting, pilot relief cartridge designed for remote pressure control in hydraulic systems. This valve is ideal for applications where load holding is crucial, as it effectively prevents overpressure by controlling the pressure settings of other pilot-operated valves. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability in various environments. The cartridge is suitable for use with phosphate ester fluids when equipped with EPDM seals; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. This corrosion-resistant valve incorporates Sun's floating style construction to minimize internal binding due to installation torque or machining variations. It operates with a maximum capacity of 0.5 gpm (2 L/min) and can withstand pressures up to 5000 psi (350 bar). The response time of this valve is typically around 2 ms, making it fast and efficient for its intended use. The RBAAJEN model features an adjustable setting range, which can be modified using the W or Y control options. When no special setting is specified, the valve remains adjustable throughout its full range. For added protection against corrosive environments, external components are available in stainless steel or zinc-nickel plating, identified by model code suffixes AP or LH. Installation requires specific torque values: 45 - 50 lbf ft (61 - 68 Nm) for the valve and 80 - 90 lbf in (9 - 10 Nm) for the locknut. The adjustment screw has an internal hex size of 5/32 in. (4 mm), while the locknut hex size measures 9/16 in. (15 mm). With a compact weight of just .50 lb (0.25 kg), this cartridge offers robust performance and adaptability across various hydraulic applications.
