The Sun Hydraulics RBADODV (RBADODV) is a direct-acting, pilot relief cartridge designed to enhance hydraulic system control through its unique configuration incorporating back-to-back check valves. This feature allows the valve to remotely control two other pilot-operated valves or serve as a thermal relief for both ends of an actuator, making it suitable for load-holding applications. The valve's capacity is limited to pilot flow, so it should be used in conjunction with other valves that have comparable pilot flows. The back-to-back check valves effectively prevent cross talk between the two remotely controlled valves, and a single adjustment can control both. The RBADODV features a check cracking pressure of 15 psi (1 bar), and pressure at port 3 is directly additive to the valve setting. It incorporates Sun's floating style construction, minimizing the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With a cavity T-11A Series 1 capacity of 0.25 gpm (1 L/min) and typical response time of 2 ms, this valve ensures efficient system performance. Additional specifications include a maximum valve leakage at 110 SUS (24 cSt) of 5 drops/min (0.3 cc/min), with adjustment settings that increase with five clockwise turns. The valve hex size is 7/8 inch (22.2 mm), and installation torque ranges from 30 to 35 lbf ft (41 to 47 Nm). It also features an internal hex size adjustment screw of 5/32 inch (4 mm) and locknut hex size of 9/16 inch (15 mm), with locknut torque ranging from 80 to 90 lbf in (9 to 10 Nm). The cartridge seal kit uses Viton material, identified by part number 990011006.
