The Sun Hydraulics RBADOEN (Material Number: RBADOEN) is a direct-acting, pilot relief cartridge featuring back-to-back check valves. This design enables it to remotely control two other pilot-operated valves or serve as a thermal relief for both ends of an actuator. Its capacity is limited to pilot flow, making it suitable for use with other valves that have comparable pilot flows. The back-to-back check valves are designed to prevent cross-talk between the two remote-controlled valves, and a single adjustment can control both. The valve's check cracking pressure is set at 15 psi (1 bar), and the pressure at port 3 adds directly to the valve setting, making it suitable for load-holding applications. The thermal relief function prevents overpressure due to thermal expansion of the fluid. The RBADOEN incorporates Sun's floating style construction, which minimizes the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. It fits into a T-11A cavity and has a series 1 capacity of 0.25 gpm (1 L/min). Typical response time is around 2 ms, with maximum valve leakage at 110 SUS (24 cSt) being 5 drops/min (0.3 cc/min). The adjustment requires five clockwise turns to increase the setting, with various hex sizes specified for different components: valve hex size is 7/8 inch (22.2 mm), adjustment screw internal hex size is 5/32 inch (4 mm), and locknut hex size is 9/16 inch (15 mm). Installation torque for the valve ranges from 30 to 35 lbf\u00b7ft (41 to 47 Nm), while locknut torque ranges from 80 to 90 lbf\u00b7in (9 to 10 Nm). A Viton seal kit (990011006) is available for this cartridge model.
