The Sun Hydraulics RBACJBV (RBACJBV) is a direct-acting pilot relief cartridge valve designed for use in hydraulic systems to remotely control the pressure setting of other pilot-operated valves. This valve is optimal for applications requiring load holding capabilities and should be used in conjunction with higher flow valves due to its limited capacity to pilot flow. It features EPDM seals, making it suitable for systems utilizing phosphate ester fluids, while exposure to petroleum-based fluids can damage the seals. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability. This model is particularly effective in environments that demand corrosion resistance, with options available for external stainless steel components or zinc-nickel plating, identifiable by the model code suffixes AP or LH. It incorporates Sun's floating style construction, which minimizes internal parts binding due to installation torque or cavity machining variations. The RBACJBV operates within a cavity T-10A and Series 1 configuration, offering a capacity of 0.25 gpm (1 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). The response time is typically around 2 ms with minimal valve leakage at 110 SUS (24 cSt). Adjustments can be made using the W or Y controls throughout its full range unless a special setting is specified. The valve's dimensions include a hex size of 7/8 inch (22.2 mm), an installation torque range of 30 - 35 lbf ft (41 - 47 Nm), and an adjustment screw internal hex size of 5/32 inch (4 mm). The locknut hex size is 9/16 inch (15 mm) with a torque specification of 80 - 90 lbf in (9 - 10 Nm). The model weighs approximately .30 lb (.15 kg) and utilizes Viton seal kits under part number: 990010006.
