The Sun Hydraulics RBATTWN (Material Number: RBATTWN) is a direct-acting, pilot relief cartridge designed to remotely control the pressure setting of other pilot-operated valves. This component is ideal for use in load holding applications, where it can effectively manage pressure settings due to its capacity being limited to pilot flow. It features a main stage orifice protected by a 150-micron stainless steel screen, ensuring durability and reliability in various conditions. The valve's construction incorporates Sun's floating style design, which minimizes the risk of internal parts binding from excessive installation torque or cavity/cartridge machining variations. The RBATTWN model is suitable for applications requiring precise pressure control, as back pressure on the tank port (port 2) directly adds to the valve setting at a 1:1 ratio. It has a cavity T-10A with a series 1 capacity of 0.25 gpm (1 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). The typical response time for this model is approximately 2 milliseconds, and it has minimal valve leakage at 110 SUS (24 cSt), rated at only five drops per minute (0.3 cc/min). For adjustments, the RBATTWN allows up to five clockwise turns to increase the setting, with specific torque requirements for installation and adjustment components: valve hex size is 7/8 inch (22.2 mm), installation torque ranges between 30-35 lbf ft (41-47 Nm), adjustment screw internal hex size is 5/32 inch (4 mm), locknut hex size is 9/16 inch (15 mm), and locknut torque ranges between 80-90 lbf in (9-10 Nm). The model weighs approximately .30 lb (.15 kg) and utilizes Viton seal kits for optimal performance.
