The Sun Hydraulics RBADKCN (RBADKCN) is a direct-acting, pilot relief cartridge designed with back-to-back check valves, making it suitable for controlling two other pilot-operated valves or functioning as a thermal relief for both ends of an actuator. This design ensures that cross talk between the two remotely controlled valves is prevented, with a single adjustment managing both. The valve is ideal for applications requiring load holding and thermal relief to prevent overpressure from fluid expansion. It features a check cracking pressure of 15 psi (1 bar), and pressure at port 3 adds directly to the valve setting. The RBADKCN has a capacity limited to pilot flow, thus it should be paired with other valves of similar pilot flow capacities. It incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations in the cavity/cartridge. The valve's cavity is T-11A, Series 1, with a capacity of 0.25 gpm (1 L/min) and typical response time of 2 ms. Maximum leakage at 110 SUS (24 cSt) is limited to 5 drops/min (0.3 cc/min). Adjustment can be made by turning clockwise up to five turns to increase the setting, with an internal hex size of 5/32 in (4 mm) for the adjustment screw and a locknut hex size of 9/16 in (15 mm). The valve should be installed with a torque between 30-35 lbf ft (41-47 Nm), while the locknut requires a torque of 80-90 lbf in (9-10 Nm). A Viton seal kit is available under part number 990011006, ensuring compatibility and durability for various hydraulic applications.
