The Sun Hydraulics RBADCDV (RBADCDV) is a direct-acting, pilot relief cartridge designed with back-to-back check valves, enabling it to remotely control two other pilot-operated valves or serve as a thermal relief for both ends of an actuator. This valve is suitable for applications where capacity is limited to pilot flow and should be used in conjunction with other valves of comparable pilot flows. The back-to-back check valves are engineered to prevent cross-talk between the two remote-controlled valves. A single adjustment mechanism allows control over both valves, with a check cracking pressure set at 15 psi (1 bar). The pressure at port 3 adds directly to the valve setting, making it ideal for load-holding applications. The thermal relief feature prevents overpressure due to fluid thermal expansion. The RBADCDV incorporates Sun's floating style construction, which minimizes the risk of internal parts binding from excessive installation torque or variations in cavity/cartridge machining. It fits into the T-11A cavity and has a series 1 capacity of 0.25 gpm (1 L/min), with a typical response time of 2 milliseconds and maximum valve leakage at 110 SUS (24 cSt) of 5 drops/minute (0.3 cc/min). To adjust the setting, turn clockwise up to five times; 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). The internal hex size for adjustment screws is 5/32 inch (4 mm), while the locknut hex size measures 9/16 inch (15 mm) with a torque range of 80 to 90 lbf in (9 to 10 Nm). The seal kit for this cartridge uses Viton material, part number: 990011006.
