The Sun Hydraulics RBACYCV (Material Number: RBACYCV) is a direct-acting, pilot relief cartridge valve designed for remote pressure control in hydraulic systems. This valve is particularly suited for applications where it works in conjunction with higher flow pilot-operated valves, given its capacity is limited to pilot flow. It features EPDM seals specifically for systems utilizing phosphate ester fluids, as exposure to petroleum-based substances can cause damage. The main stage orifice is safeguarded by a 150-micron stainless steel screen, making it suitable for load-holding applications. Notably, any back pressure on the tank port (port 2) directly adds to the valve setting at a 1:1 ratio. The RBACYCV model employs Sun's floating style construction, minimizing internal part binding due to excessive installation torque or machining variations. It boasts a maximum operating pressure of 5000 psi (350 bar) and a typical response time of 2 milliseconds. The valve allows adjustment throughout its full range using W or Y controls unless a special setting is specified, which then serves as the maximum setting. Corrosion-resistant options are available with external stainless steel components (suffix AP) or zinc-nickel plated components (suffix LH). The valve's hex size measures 7/8 inches (22.2 mm), while its installation torque ranges between 30 and 35 lbf ft (41 to 47 Nm). The adjustment screw has an internal hex size of 5/32 inches (4 mm), and the locknut requires a torque of between 80 and 90 lbf in (9 to 10 Nm). Weighing just .30 lb (.15 kg), this cartridge valve is compact yet robust for various hydraulic applications.
