The Sun Hydraulics RBACMBV (RBACMBV) is a direct-acting, pilot relief cartridge valve designed for remote pressure control in hydraulic systems. This valve is intended to work alongside higher flow pilot-operated valves due to its limited capacity for pilot flow. It features EPDM seals, making it suitable for systems using phosphate ester fluids, while exposure to petroleum-based fluids can damage these seals. The main stage orifice is protected by a 150-micron stainless steel screen, ensuring durability and reliability in load-holding applications. The valve's setting can be adjusted with W and Y controls, with an option for special settings that define the maximum limit of the valve's range. This corrosion-resistant cartridge is ideal for harsh environments and offers configurations with either stainless steel or zinc-nickel plated components. It utilizes Sun's floating style construction to prevent internal binding from excessive installation torque or machining variations. The RBACMBV fits a T-10A cavity and operates at a maximum pressure of 5000 psi (350 bar) with a response time of approximately 2 milliseconds. It allows a maximum leakage rate of 5 drops per minute at 110 SUS (24 cSt). The valve requires specific installation torques: 30-35 lbf ft (41-47 Nm) for the valve itself and 80-90 lbf in (9-10 Nm) for the locknut. The RBACMBV weighs .30 lb (.15 kg) and includes adjustment screws that require a 5/32 inch internal hex size tool. This model is particularly fast, stable, dirt-tolerant, and robust, making it an excellent choice for preventing overpressure in hydraulic systems where precise pressure control is essential.
