The Sun Hydraulics RBADCBV (RBADCBV) 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 function as a thermal relief for both ends of an actuator. This valve is ideal for applications requiring load holding and prevention of overpressure due to thermal expansion of fluid. It is important to note that its capacity is limited to pilot flow, making it suitable for use with other valves that have comparable pilot flows. The back-to-back check valves are essential in preventing cross-talk between the two controlled valves, and a single adjustment can manage both. The valve features a check cracking pressure of 15 psi (1 bar), and any pressure at port 3 directly adds to the valve setting. The RBADCBV incorporates Sun's floating style construction, which minimizes the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. It fits into a T-11A cavity and has a series 1 capacity of 0.25 gpm (1 L/min). The typical response time is approximately 2 milliseconds, with maximum valve leakage at 110 SUS (24 cSt) being limited to 5 drops/minute (0.3 cc/min). Adjustments are made via an internal hex screw, with specific torque requirements for installation and locknut adjustments ensuring secure operation. Additionally, the valve includes Viton seals as part of its construction, ensuring compatibility with various hydraulic fluids and temperature ranges.
