The Sun Hydraulics RBADOAV (Material Number: RBADOAV) is a direct-acting, pilot relief cartridge designed with back-to-back check valves. This configuration enables it to remotely control two other pilot-operated valves or serve as a thermal relief for both ends of an actuator. It is particularly suitable for load-holding applications due to its ability to prevent overpressure caused by thermal expansion of the fluid. The valve's capacity is limited to pilot flow, making it ideal for use with other valves that have comparable pilot flows. The back-to-back check valves are engineered to prevent cross-talk between the two remote-controlled valves, and a single adjustment controls both valves simultaneously. The valve features a check cracking pressure of 15 psi (1 bar), and the pressure at port 3 is directly additive to the valve setting. Its construction incorporates Sun's floating style design, minimizing the risk of internal parts binding due to excessive installation torque or cavity/cartridge machining variations. The RBADOAV has a cavity T-11A Series 1 and a capacity of 0.25 gpm (1 L/min), with a typical response time of 2 milliseconds. Maximum valve leakage at 110 SUS (24 cSt) is limited to 5 drops/minute (0.3 cc/minute). For installation, the valve requires a hex size of 7/8 inch (22.2 mm) and an installation torque between 30 - 35 lbf ft (41 - 47 Nm). The adjustment screw has an internal hex size of 5/32 inch (4 mm), while the locknut hex size is 9/16 inch (15 mm) with a locknut torque range of 80 - 90 lbf in (9 -10 Nm). It utilizes Viton seal kits, specifically part number: 990011006, ensuring reliable performance under various conditions.
