The Sun Hydraulics RBAAJAN (RBAAJAN) is a direct-acting, pilot relief cartridge valve designed to remotely control the pressure setting of other pilot-operated valves. This component is optimized for load holding applications and should be used in conjunction with higher flow valves due to its capacity being limited to pilot flow. It features a main stage orifice protected by a 150-micron stainless steel screen, ensuring durability and reliability in various conditions. The valve's design allows back pressure on the tank port (port 2) to be directly additive to the valve setting at a 1:1 ratio, enhancing its precision in pressure control. This model is suitable for systems using phosphate ester fluids when equipped with EPDM seals; however, exposure to petroleum-based fluids can damage these seals. For environments prone to corrosion, the RBAAJAN can be configured with corrosion-resistant materials, identified by suffixes AP or LH in the model code. The valve incorporates Sun's floating style construction, which minimizes internal binding due to excessive installation torque or machining variations. The RBAAJAN operates within a maximum pressure of 5000 psi (350 bar) and offers a capacity of 0.5 gpm (2 L/min). It has a typical response time of 2 ms and minimal leakage at standard viscosity levels. Adjustments can be made throughout its full range using W or Y controls unless specified otherwise for special settings. The cartridge's compact design includes specific installation requirements such as torque specifications and hex sizes for both the valve and locknut components. Overall, this versatile valve provides robust performance in controlling hydraulic systems' pressure settings while offering customization options for various operational needs and environmental conditions.
