The Sun Hydraulics RBAALCN (RBAALCN) is a direct-acting, pilot relief cartridge designed to remotely control the pressure setting of other pilot-operated valves. This component is specifically engineered for use in load-holding applications and should be paired with higher flow valves due to its limited capacity to pilot flow. It features a main stage orifice protected by a 150-micron stainless steel screen, ensuring durability and reliability in various conditions. The cartridge is suitable for systems using phosphate ester fluids when configured with EPDM seals, but it should not be exposed to petroleum-based fluids as they can damage the seals. This model supports back pressure on the tank port, which is directly additive to the valve setting at a 1:1 ratio. The Sun Hydraulics RBAALCN incorporates floating style construction, minimizing the risk of internal parts binding due to excessive installation torque or machining variations. It offers corrosion resistance with external components available in stainless steel or zinc-nickel plating, identified by model code suffixes AP or LH respectively. With a capacity of 0.5 gpm (2 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve responds typically within 2 milliseconds and has minimal leakage rates at specified conditions. The adjustment can be made through five clockwise turns to increase settings, with specific dimensions provided for installation and adjustment tools. This valve's robust design makes it ideal for applications where quick response and stability are critical, providing effective overpressure prevention in hydraulic systems.
