The Sun Hydraulics RBAAOWN (RBAAOWN) is a direct-acting, pilot relief cartridge designed to remotely control the pressure setting of other pilot-operated valves. This cartridge valve is specifically engineered for applications where capacity is limited to pilot flow and is ideal for use in load-holding scenarios. It features a main stage orifice protected by a 150-micron stainless steel screen, ensuring durability and reliability. The valve's design allows back pressure on the tank port (port 2) to be directly additive to the valve setting at a 1:1 ratio, enhancing its adaptability in various systems. The RBAAOWN model can be configured with EPDM seals, making it suitable for systems using phosphate ester fluids while cautioning against exposure to petroleum-based substances that could damage the seals. Additionally, corrosion-resistant options are available, identified by model code suffixes AP or LH, featuring external stainless steel or zinc-nickel plated components respectively. The cartridge incorporates Sun's floating style construction to minimize internal part binding due to excessive torque or machining variations. This Series 2 cartridge has a capacity of 0.5 gpm (2 L/min) and can operate at a maximum pressure of 5000 psi (350 bar), with a typical response time of 2 ms. It boasts minimal leakage rates and offers adjustable settings through its W or Y controls, providing flexibility in application-specific configurations. The valve's installation specifications include a hex size of 1-1/8 inches and an installation torque range of 45-50 lbf-ft (61-68 Nm). With its robust design and versatile capabilities, the Sun Hydraulics RBAAOWN serves as an efficient solution for controlling hydraulic pressure in demanding environments.
