The Sun Hydraulics RBACLBV (RBACLBV) is a direct-acting, pilot relief cartridge designed for remote pressure control in hydraulic systems. It is primarily used to set the pressure of other pilot-operated valves and is suitable for load-holding applications. The valve operates with a maximum capacity of 0.25 gpm (1 L/min) and can handle pressures up to 5000 psi (350 bar). The RBACLBV features a main stage orifice protected by a 150-micron stainless steel screen, ensuring reliability and durability in operation. This cartridge valve incorporates Sun's floating style construction, which reduces the potential for internal part binding caused by excessive installation torque or machining variations in the cavity or cartridge. The valve's response time is typically around 2 milliseconds, with a maximum leakage rate of 5 drops per minute at 110 SUS (24 cSt). It includes adjustment capabilities via an internal hex screw and locknut, allowing for precise pressure settings with up to five clockwise turns to increase the setting. The RBACLBV model offers corrosion-resistant options identified by suffixes AP or LH, indicating external stainless steel components or zinc-nickel plating, respectively. For systems using phosphate ester fluids, cartridges with EPDM seals are recommended; however, exposure to petroleum-based fluids should be avoided as it may damage these seals. Additionally, back pressure on the tank port directly affects the valve setting at a 1:1 ratio. The valve is designed for easy installation with specific torque requirements: valve installation torque ranges from 30 to 35 lbf ft (41 to 47 Nm), and locknut torque ranges from 80 to 90 lbf in (9 to 10 Nm). The compact design has a weight of approximately .30 lb (.15 kg), making it an efficient choice for various hydraulic applications requiring precise pressure control.
