The Sun Hydraulics RBADKAV (RBADKAV) 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 serve as a thermal relief for both ends of an actuator. Designed for applications where capacity is limited to pilot flow, this valve is ideal for use with other valves that have comparable pilot flows. The back-to-back check valves prevent cross-talk between the two controlled valves, and a single adjustment manages both. With a check cracking pressure of 15 psi (1 bar), the pressure at port 3 adds directly to the valve setting, making it suitable for load-holding applications. The valve's thermal relief capability prevents overpressure due to fluid thermal expansion. It incorporates Sun's floating style construction to minimize internal part binding from excessive installation torque or cavity/cartridge machining variations. This Series 1 cartridge fits into a T-11A cavity and has a capacity of 0.25 gpm (1 L/min). It offers a typical response time of 2 ms and maximum valve leakage at 110 SUS (24 cSt) of 5 drops/min (0.3 cc/min). The adjustment mechanism allows up to five clockwise turns to increase the setting. Installation requires a valve hex size of 7/8 in. (22.2 mm) and torque between 30-35 lbf ft (41-47 Nm). The internal hex size for adjustment screws is 5/32 in. (4 mm), while the locknut hex size is 9/16 in. (15 mm) with a torque range of 80-90 lbf in. (9-10 Nm). This product comes with a Viton seal kit under part number 990011006, ensuring reliable performance across various hydraulic systems requiring precise pressure control and thermal relief functions.
