The Sun Hydraulics RBACTDV (RBACTDV) is a direct-acting, pilot relief cartridge designed to remotely control the pressure setting of other pilot-operated valves. This model is optimized for use with higher flow valves due to its capacity being limited to pilot flow. It features EPDM seals suitable for systems with phosphate ester fluids, though they are incompatible with petroleum-based substances, which can cause damage. The main stage orifice is safeguarded by a 150-micron stainless steel screen, enhancing its durability in load-holding applications. Notably, back pressure on the tank port directly influences the valve setting at a 1:1 ratio. The RBACTDV offers adjustable settings through W and Y controls, allowing users to fine-tune it across its full range unless a special maximum setting is specified. Corrosion resistance is another key feature; cartridges can be configured with either stainless steel or zinc-nickel plated components for enhanced durability in corrosive environments. The floating style construction minimizes internal part binding due to excessive installation torque or machining variations. Key specifications include a cavity T-10A Series 1 capacity of 0.25 gpm (1 L/min), maximum operating pressure of 5000 psi (350 bar), and typical response time of 2 ms. The valve exhibits minimal leakage at standard conditions and includes adjustable components such as an internal hex adjustment screw and locknut with specified torque values. With a weight of just 0.30 lb (0.15 kg), this cartridge valve is lightweight yet robust, making it an ideal choice for precise pressure control in various hydraulic applications where reliability and performance are critical.
