The Sun Hydraulics RBAAJBV (RBAAJBV) is a direct-acting, pilot relief cartridge designed to remotely control the pressure setting of other pilot-operated valves. It is specifically intended for use in load-holding applications, where it provides reliable performance by limiting capacity to pilot flow. This valve incorporates a 150-micron stainless steel screen to protect the main stage orifice and can handle a maximum operating pressure of 5000 psi (350 bar). It is suitable for systems using phosphate ester fluids when configured with EPDM seals, though exposure to petroleum-based fluids should be avoided as it may damage the seals. The RBAAJBV model features corrosion-resistant construction options, denoted by suffixes AP for stainless steel components or LH for zinc-nickel plating, making it ideal for use in corrosive environments. This valve allows back pressure on the tank port (port 2) to be directly additive to the valve setting at a 1:1 ratio. The adjustment can be made using W or Y controls throughout its full range unless a special setting is specified, which then represents the maximum setting of the valve. The model incorporates Sun's floating style construction, minimizing potential internal part binding due to excessive installation torque or cavity/cartridge machining variations. With a capacity of 0.5 gpm (2 L/min) and typical response time of 2 ms, this cartridge valve offers efficient performance with minimal leakage at maximum conditions. Installation requires specific torque settings and hex sizes for adjustments and locknuts. The RBAAJBV weighs approximately 0.50 lb (0.25 kg) and utilizes Viton seal kits (990203006) for optimal sealing performance.
