The Sun Hydraulics RBACTEN (Material Number: RBACTEN) is a direct-acting, pilot relief cartridge designed to remotely control the pressure setting of other pilot-operated valves. This valve is specifically tailored for applications where capacity is limited to pilot flow, making it ideal for integration with higher flow valves. Notably, cartridges with EPDM seals are compatible with phosphate ester fluids but should not be exposed to petroleum-based fluids, greases, or lubricants due to potential seal damage. The main stage orifice is safeguarded by a 150-micron stainless steel screen, enhancing its suitability for load-holding applications. The valve's setting can be adjusted using W and Y controls across its full range unless a special maximum setting is specified. It features corrosion-resistant options identified by model code suffixes AP or LH, indicating external stainless steel or zinc-nickel plated components respectively. The Sun floating style construction minimizes the risk of internal parts binding due to excessive installation torque or machining variations. The RBACTEN operates within a cavity T-10A and offers a series 1 capacity of 0.25 gpm (1 L/min) with a maximum operating pressure of 5000 psi (350 bar). It boasts a typical response time of 2 ms and exhibits minimal leakage at 5 drops/min (0.3 cc/min) at 110 SUS (24 cSt). For adjustments, the valve requires approximately five clockwise turns to increase the setting and features specific hex sizes for various components to ensure precise installation and adjustment torque specifications are met. Weighing in at .30 lb (.15 kg), this cartridge valve provides robust performance in demanding environments while maintaining stability and dirt tolerance.
