The Sun Hydraulics RBAALAV (RBAALAV) is a direct-acting, pilot relief cartridge valve designed for remote pressure control in systems using other pilot-operated valves. This valve is optimal for applications requiring load holding capabilities and should be paired with high-flow valves due to its limited pilot flow capacity. The main stage orifice is safeguarded by a 150-micron stainless steel screen, enhancing its durability and reliability. It features a unique floating style construction that minimizes internal binding risks caused by excessive installation torque or machining variations. The valve's design accommodates back pressure on the tank port, which directly affects the valve setting at a 1:1 ratio. This model can be configured with EPDM seals for compatibility with phosphate ester fluids, but it is crucial to avoid petroleum-based fluids as they can damage the seals. The RBAALAV offers corrosion-resistant options identified by suffixes AP or LH for external stainless steel or zinc-nickel plated components, respectively. With a cavity size of T-3A and a series of 2, it has a capacity of 0.5 gpm (2 L/min) and operates at a maximum pressure of 5000 psi (350 bar). The response time is typically around 2 ms, with minimal leakage rates. Adjustments are made via an internal hex screw, requiring up to five clockwise turns to increase settings. Installation requires specific torque values for both the valve and locknut to ensure proper function and stability. Weighing just 0.50 lb (0.25 kg), this compact cartridge valve is robust and stable, making it suitable for various hydraulic applications where precise pressure control is essential.
