The Sun Hydraulics RBADCEN (RBADCEN) is a direct-acting, pilot relief cartridge that features back-to-back check valves, enabling it to remotely control two other pilot-operated valves or act as a thermal relief for both ends of an actuator. Designed for applications where capacity is limited to pilot flow, this valve should be paired with other valves of similar pilot flows. The back-to-back check valves are engineered to prevent cross-talk between the two remotely controlled valves, and a single adjustment can control both. The check cracking pressure stands at 15 psi (1 bar), with pressure at port 3 being directly additive to the valve setting, making it suitable for load-holding applications. The term \"thermal relief\" refers to its capability to prevent overpressure resulting from thermal fluid expansion. Constructed with Sun's floating style design, the valve minimizes the risk of internal components 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 approximately 2 ms, and maximum valve leakage at 110 SUS (24 cSt) is rated at 5 drops/min (0.3 cc/min). Adjustment involves five clockwise turns to increase the setting, with specific hex sizes and torque specifications provided for both the valve and locknut components. This robust design ensures stability and dirt tolerance in various demanding scenarios while offering precise control over hydraulic systems.
