The Sun Hydraulics RBACQAV (RBACQAV) is a specialized direct-acting pilot relief cartridge designed for remote pressure control in hydraulic systems. This valve is ideal for load-holding applications, with a specific capacity limited to pilot flow, necessitating its use alongside higher flow valves. It features EPDM seals suitable for systems utilizing phosphate ester fluids, but these seals should not be exposed to petroleum-based fluids, greases, or lubricants due to potential damage. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability in operation. The RBACQAV model offers an adjustable valve setting using W and Y controls, with the option for a special setting that denotes the valve\u2019s maximum setting. This product is corrosion-resistant, available with external stainless steel components (suffix AP) or zinc-nickel plated components (suffix LH), making it well-suited for corrosive environments. The design incorporates Sun's floating style construction to reduce internal part binding due to excessive installation torque or machining variations. Key specifications include a cavity T-10A series 1 design with a capacity of 0.25 gpm (1 L/min) and a maximum operating pressure of 5000 psi (350 bar). The typical response time is approximately 2 ms, with minimal leakage at 110 SUS (24 cSt), measured at 5 drops/min (0.3 cc/min). The valve features an adjustment screw internal hex size of 5/32 inch (4 mm) and requires an installation torque between 30-35 lbf ft (41-47 Nm). The locknut hex size is 9/16 inch (15 mm), with a torque specification of 80-90 lbf in (9-10 Nm). The model weighs approximately 0.30 lb (0.15 kg), and the seal kit cartridge Viton number is 990010006.
