The Sun Hydraulics RBAAJAV (RBAAJAV) is a direct-acting, pilot relief cartridge designed to remotely control the pressure setting of other pilot-operated valves. With a capacity limited to pilot flow, it is ideally used in conjunction with higher flow valves. This model features a main stage orifice protected by a 150-micron stainless steel screen, making it suitable for load holding applications. It is important to note that back pressure on the tank port is directly additive to the valve setting at a 1:1 ratio. The valve can be configured with EPDM seals for systems using phosphate ester fluids; however, exposure to petroleum-based fluids will damage these seals. The RBAAJAV incorporates Sun's floating style construction, reducing the risk of internal parts binding due to excessive installation torque or cavity/cartridge machining variations. It has a maximum operating pressure of 5000 psi (350 bar) and offers a typical response time of 2 milliseconds. The valve ensures minimal leakage with a maximum rate of 5 drops/minute at 110 SUS (24 cSt). Adjustments can be made using the internal hex screw, with up to five clockwise turns available to increase settings. This model also offers corrosion-resistant options identified by suffixes AP or LH for external stainless steel or zinc-nickel plated components respectively, catering to use in corrosive environments. The RBAAJAV weighs approximately 0.50 lb (0.25 kg) and requires specific installation torques for optimal performance: valve installation torque between 45-50 lbf ft (61-68 Nm), and locknut torque between 80-90 lbf in (9-10 Nm).
