The Sun Hydraulics RBATQWV (RBATQWV) is a direct-acting, pilot relief cartridge designed for precise pressure control in hydraulic systems. This component is particularly useful for remotely controlling the pressure settings of other pilot-operated valves, making it ideal for systems that require high responsiveness and accuracy. The valve's design includes a main stage orifice protected by a 150-micron stainless steel screen, ensuring durability and reliability in various applications, including load-holding scenarios. It features Sun's floating style construction, which minimizes the risk of internal parts binding due to excessive installation torque or machining variations. This cartridge valve operates with a capacity of 0.25 gallons per minute (1 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). Its typical response time is approximately 2 milliseconds, providing rapid adjustments to pressure changes. The valve's leakage rate at 110 SUS (24 cSt) is minimal, at just 5 drops per minute (0.3 cc/min), ensuring efficient operation without significant fluid loss. Installation requires specific torque settings: the valve hex size is 7/8 inch (22.2 mm), with an installation torque range between 30 to 35 lbf-ft (41 to 47 Nm). The adjustment screw has an internal hex size of 5/32 inch (4 mm), and the locknut hex size is 9/16 inch (15 mm) with a torque setting of 80 to 90 lbf-in (9 to 10 Nm). Weighing in at just .30 lb (.15 kg), this compact yet robust cartridge is suitable for various hydraulic applications requiring reliable pressure control. Additionally, the RBATQWV incorporates back pressure on the tank port directly additive to the valve setting at a ratio of 1:1, enhancing its adaptability in diverse operational conditions.
