The Sun Hydraulics RBADOBN (RBADOBN) is a direct-acting, pilot relief cartridge designed with back-to-back check valves, allowing it to remotely control two other pilot-operated valves or serve as a thermal relief for both ends of an actuator. This design is suitable for load-holding applications and prevents cross-talk between the two controlled valves, with one adjustment managing both. The check cracking pressure is set at 15 psi (1 bar), and pressure at port 3 adds directly to the valve setting. The valve's capacity is limited to pilot flow, indicating it should be paired with other valves that have comparable pilot flows. It incorporates Sun\u2019s floating style construction, minimizing internal part binding due to excessive installation torque or variations in cavity/cartridge machining. The RBADOBN features a cavity size of T-11A Series 1 with a capacity of 0.25 gpm (1 L/min) and a typical response time of 2 ms. Its maximum valve leakage at 110 SUS (24 cSt) is minimal, at just 5 drops/min (0.3 cc/min). The adjustment mechanism allows for up to five clockwise turns to increase the setting, with specific torque requirements for installation and locknut adjustments: valve installation torque ranges from 30 to 35 lbf ft (41 to 47 Nm), while locknut torque ranges from 80 to 90 lbf in (9 to 10 Nm). This product includes a Viton seal kit under cartridge number 990011006.
