The Sun Hydraulics RBAAOWV (RBAAOWV) is a direct-acting, pilot relief cartridge designed for remote pressure control in hydraulic systems. It is intended for use with other higher flow valves due to its limited capacity to pilot flow. The cartridge features a main stage orifice protected by a 150-micron stainless steel screen, making it suitable for load-holding applications. It is important to note that back pressure on the tank port (port 2) directly affects the valve setting at a 1:1 ratio. For systems using phosphate ester fluids, cartridges with EPDM seals are available, as exposure to petroleum-based fluids can damage these seals. This model incorporates Sun's floating style construction, reducing the risk of internal part binding due to excessive installation torque or machining variations in the cavity/cartridge. The RBAAOWV can be configured with corrosion-resistant components, either with an AP suffix for external stainless steel parts or an LH suffix for zinc-nickel plated parts. With a capacity of 0.5 gpm (2 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve exhibits a typical response time of 2 ms and minimal leakage at maximum conditions. The valve allows adjustment through its W or Y controls across its full range unless specified otherwise for a special setting. Installation requires specific torque values: valve installation torque ranges from 45-50 lbf ft (61-68 Nm), and locknut torque ranges from 80-90 lbf in (9-10 Nm). The valve weighs approximately 0.50 lb (0.25 kg) and utilizes Viton seal kits for optimal performance in compatible environments.
