The Sun Hydraulics RBAAJWV (RBAAJWV) is a direct-acting, pilot relief cartridge valve designed for remote pressure control in hydraulic systems. This valve is ideal for use in load-holding applications and works by controlling the pressure setting of other pilot-operated valves, with its capacity limited to pilot flow. It features a main stage orifice protected by a 150-micron stainless steel screen, ensuring durability and reliability. The valve can handle back pressure on the tank port at a 1:1 ratio directly additive to the valve setting. It's important to note that cartridges with EPDM seals are compatible with phosphate ester fluids only; exposure to petroleum-based fluids will damage these seals. The RBAAJWV model incorporates Sun's floating style construction, which minimizes binding due to excessive installation torque or machining variations. It is corrosion-resistant, available with external stainless steel components (suffix AP) or zinc-nickel plated components (suffix LH). With a cavity T-3A and Series 2 capacity of 0.5 gpm (2 L/min), this cartridge can operate at a maximum pressure of 5000 psi (350 bar) and has a typical response time of 2 ms. The maximum valve leakage is minimal at 5 drops/minute (0.3 cc/min). For adjustments, the valve requires five clockwise turns to increase settings and features an internal hex size adjustment screw of 5/32 inches (4 mm). The installation torque ranges from 45 to 50 lbf ft (61 to 68 Nm), while the locknut torque ranges from 80 to 90 lbf in (9 to 10 Nm). Weighing just .50 lb (0.25 kg), it offers robust performance in demanding environments.
