The Sun Hydraulics RBACLBE (RBACLBE) is a direct-acting, pilot relief cartridge designed for precise pressure control in hydraulic systems. This cartridge is specifically utilized to remotely manage the pressure settings of other pilot-operated valves, with its capacity limited to pilot flow, making it suitable for integration with higher flow valves. It features EPDM seals that are compatible with phosphate ester fluids, but caution must be exercised as exposure to petroleum-based fluids can damage these seals. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability even in corrosive environments. Notably, this valve is effective in load-holding applications and has a back pressure on the tank port that directly influences the valve setting at a 1:1 ratio. The RBACLBE model incorporates Sun's floating style construction to minimize potential internal binding due to excessive installation torque or machining variations. It operates within a cavity T-10A Series 1 and has a capacity of 0.25 gpm (1 L/min), withstanding a maximum operating pressure of 5000 psi (350 bar). The response time is typically around 2 milliseconds, and it exhibits minimal leakage at maximum conditions\u2014approximately 5 drops/minute (0.3 cc/min). Adjustments can be made with up to five clockwise turns to increase the setting, utilizing an internal hex size adjustment screw of 5/32 inches (4 mm). The locknut requires a torque of 80\u201390 lbf-in (9\u201310 Nm) for secure installation. The corrosion-resistant design options include external stainless steel components or zinc-nickel plating for enhanced longevity in harsh environments. Weighing approximately 0.30 lb (0.15 kg), this cartridge valve is engineered for robust performance and adaptability across various hydraulic applications requiring precise pressure regulation and control.
