The Sun Hydraulics RBADCEV (RBADCEV) is a direct-acting, pilot relief cartridge designed to incorporate back-to-back check valves. This unique configuration enables the valve to remotely control two other pilot-operated valves or function as a thermal relief for both ends of an actuator. It is particularly suitable for load-holding applications due to its ability to prevent overpressure from thermal expansion of the fluid. The valve's capacity is limited to pilot flow, making it ideal for use with other valves that have comparable pilot flows. A key feature of this model is the prevention of cross-talk between the two controlled valves, achieved through its back-to-back check valves design. Users benefit from a single adjustment that controls both valves simultaneously, with a check cracking pressure set at 15 psi (1 bar). The pressure at port 3 directly adds to the valve setting, providing precise control in various applications. The RBADCEV model incorporates Sun's floating style construction, which minimizes potential binding of internal parts due to excessive installation torque or machining variations in cavity/cartridge construction. The valve fits into a Cavity T-11A and has a capacity of 0.25 gpm (1 L/min) with a typical response time of 2 ms. Maximum leakage at 110 SUS (24 cSt) is minimal at 5 drops/min (0.3 cc/min). For adjustments, five clockwise turns increase the setting, and it features specific hex sizes for various components\u2014valve hex size at 7/8 in. (22.2 mm), internal hex size for adjustment screw at 5/32 in. (4 mm), and locknut hex size at 9/16 in. (15 mm). Installation torque ranges from 30-35 lbf ft (41-47 Nm), while locknut torque ranges from 80-90 lbf in (9-10 Nm).
