The Sun Hydraulics RBADCCV (RBADCCV) 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 specifically suited for load holding applications and offers a solution for preventing overpressure due to thermal fluid expansion. The capacity of this valve is limited to pilot flow, thus it should be used alongside other valves with comparable pilot flows. One of its key features includes the prevention of cross-talk between the two controlled valves through its back-to-back check valve design. The valve's adjustment mechanism allows for the simultaneous control of two valves with a single adjustment point. The RBADCCV model features a check cracking pressure set at 15 psi (1 bar), and any pressure at port 3 directly adds to the valve setting. Its construction incorporates Sun's floating style design, minimizing potential internal binding due to excessive installation torque or machining variations in cavity/cartridge setups. The valve can handle a capacity of 0.25 gpm (1 L/min) and offers a quick response time typically around 2 ms. It exhibits minimal leakage at maximum conditions, rated at five drops per minute (0.3 cc/min). Installation specifications include a valve hex size of 7/8 inch (22.2 mm), an installation torque requirement between 30-35 lbf ft (41-47 Nm), and an adjustment screw internal hex size of 5/32 inch (4 mm). The locknut has a hex size of 9/16 inch (15 mm) with torque requirements ranging from 80-90 lbf in (9-10 Nm). For maintenance or replacement needs, the seal kit cartridge is compatible with Viton: 990011006.
