The Sun Hydraulics RBATCAN (Material Number: RBATCAN) is a direct-acting, pilot relief cartridge specifically designed to remotely control the pressure setting of other pilot-operated valves. It is optimized for use in load-holding applications where capacity is limited to pilot flow, necessitating its pairing with higher flow valves. The main stage orifice is protected by a 150-micron stainless steel screen, ensuring durability and reliability. This valve features Sun's floating style construction to reduce the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. It has a cavity T-10A series 1 capacity with a flow rate of 0.25 gpm (1 L/min) and can operate at a maximum pressure of 5000 psi (350 bar). The typical response time is approximately 2 ms, and it exhibits minimal leakage at 5 drops/min (0.3 cc/min) when tested with oil viscosity at 110 SUS (24 cSt). The adjustment mechanism allows for five clockwise turns to increase the setting, with specific torque requirements for installation and adjustments: valve hex size is 7/8 in. (22.2 mm), installation torque ranges from 30 to 35 lbf ft (41 to 47 Nm), adjustment screw internal hex size is 5/32 in. (4 mm), locknut hex size is 9/16 in. (15 mm), and locknut torque ranges from 80 to 90 lbf in. (9 to 10 Nm). Weighing only .30 lb (.15 kg), this cartridge incorporates Viton seals for enhanced performance and reliability under demanding conditions, making it suitable for various hydraulic applications requiring precise pressure control and stability.
