The Sun Hydraulics RBAALDV (RBAALDV) is a direct-acting, pilot relief cartridge valve designed for controlling the pressure setting of other pilot-operated valves. This component is particularly suited for load-holding applications, offering a reliable solution where back pressure on the tank port is directly additive to the valve setting at a 1:1 ratio. The valve's main stage orifice is protected by a 150-micron stainless steel screen, ensuring durability and resistance to contaminants. It features corrosion-resistant components, with options for external stainless steel or zinc-nickel plated parts, making it suitable for use in corrosive environments. This model incorporates Sun\u2019s floating style construction to minimize internal part binding due to installation torque or machining variations. The RBAALDV supports systems using phosphate ester fluids when configured with EPDM seals but should avoid exposure to petroleum-based fluids as they can damage the seals. The valve's adjustment range can be fully utilized with W or Y controls unless a special setting is specified, which then represents its maximum setting. Key specifications include a cavity size of T-3A Series 2, a capacity of 0.5 gpm (2 L/min), and a maximum operating pressure of 5000 psi (350 bar). The typical response time is 2 ms, and it has minimal leakage at maximum conditions. Installation requires specific torque settings for both the valve and locknut to ensure optimal performance. This versatile relief cartridge offers robust performance in various hydraulic systems, especially where precise pressure control and reliability are paramount.
