The Sun Hydraulics RBADOWV (RBADOWV) is a direct-acting, pilot relief cartridge designed with back-to-back check valves, making it ideal for controlling two other pilot-operated valves or serving as a thermal relief for both ends of an actuator. This valve is specifically engineered to handle pilot flow capacity and should be paired with other valves that have comparable pilot flows. The integrated check valves prevent cross-talk between the controlled valves, ensuring precise operation. One adjustment mechanism effectively manages two valves simultaneously, and the valve features a check cracking pressure of 15 psi (1 bar). Pressure at port 3 can be directly added to the valve setting, which is particularly beneficial for load-holding applications. The term \"thermal relief\" refers to its ability to prevent overpressure due to fluid thermal expansion. The RBADOWV incorporates Sun's floating style construction, which minimizes the risk of internal parts binding from excessive installation torque or variations in cavity/cartridge machining. It fits into a T-11A Series 1 cavity and offers a capacity of 0.25 gpm (1 L/min) with a typical response time of 2 ms. The maximum valve leakage at 110 SUS (24 cSt) is limited to 5 drops/min (0.3 cc/min). Adjustments can be made with up to five clockwise turns to increase the setting, using an internal hex size of 5/32 in. (4 mm), and secured by a locknut requiring a torque of 80-90 lbf in (9-10 Nm). The valve's hex size is 7/8 in. (22.2 mm), with an installation torque range between 30-35 lbf ft (41-47 Nm). For maintenance or replacement needs, Viton seal kits are available under part number 990011006.
