The Sun Hydraulics RBADLDV (RBADLDV) is a direct-acting, pilot relief cartridge designed for versatile hydraulic applications. This innovative valve integrates back-to-back check valves, enabling it to remotely control two other pilot-operated valves or function as a thermal relief for both ends of an actuator. It is essential to pair this valve with others that have comparable pilot flows due to its capacity being limited to pilot flow. The back-to-back check valves effectively prevent cross talk between the two remotely controlled valves, and a single adjustment can control both valves simultaneously. The valve features a check cracking pressure of 15 psi (1 bar), and any pressure at port 3 adds directly to the valve setting, making it suitable for load-holding applications. The term \"thermal relief\" in this context refers to the valve's ability to prevent overpressure caused by thermal expansion of the fluid. The RBADLDV incorporates Sun's floating style construction, which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. It fits into a Cavity T-11A Series 1 with a capacity of 0.25 gpm (1 L/min) and has a typical response time of 2 ms. The maximum valve leakage at 110 SUS (24 cSt) is limited to 5 drops/min (0.3 cc/min). For adjustments, it requires five clockwise turns to increase the setting, with specific hex sizes for the adjustment screw and locknut. This cartridge is designed with robust specifications such as an installation torque range of 30 - 35 lbf ft (41 - 47 Nm) and locknut torque between 80 - 90 lbf in (9 - 10 Nm). A Viton seal kit is available under part number 990011006 for maintenance purposes.
