The Sun Hydraulics RBADLEV (Material Number: RBADLEV) is a direct-acting, pilot relief cartridge designed with 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 important to note that its capacity is limited to pilot flow, making it ideal for use with other valves that have comparable pilot flows. The back-to-back check valves effectively prevent cross talk between the two remote-controlled valves. A single adjustment on this valve manages two distinct valves, with a check cracking pressure of 15 psi (1 bar). Additionally, the pressure at port 3 directly adds to the valve setting, making it suitable for load-holding applications. The term \"thermal relief\" refers to its capability to prevent overpressure caused by fluid thermal expansion. The RBADLEV incorporates Sun's floating style construction, which reduces the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. Key specifications include a cavity size of T-11A Series 1 and a capacity of 0.25 gpm (1 L/min). The typical response time is 2 ms, and maximum valve leakage at 110 SUS (24 cSt) is limited to 5 drops/min (0.3 cc/min). The adjustment requires five clockwise turns to increase the setting, and the valve hex size measures 7/8 in. (22.2 mm) with an installation torque range of 30 - 35 lbf ft (41 - 47 Nm). The adjustment screw has an internal hex size of 5/32 in. (4 mm), while the locknut hex size is 9/16 in. (15 mm) with a torque specification of 80 - 90 lbf in. (9 -10 Nm). A Viton seal kit is available under part number: 990011006 for maintenance or replacement needs.
