The Sun Hydraulics RBATCAV (RBATCAV) is a direct-acting, pilot relief cartridge designed for remote pressure control in conjunction with other pilot-operated valves. It is engineered specifically for applications requiring load holding capabilities. The main stage orifice of the valve is protected by a 150-micron stainless steel screen, ensuring durability and reliability. This cartridge is ideal for use when back pressure on the tank port (port 2) needs to be directly additive to the valve setting at a 1:1 ratio. The Sun floating style construction helps minimize internal binding due to excessive installation torque or machining variations in the cavity/cartridge. The RBATCAV has a cavity T-10A and series 1 capacity of 0.25 gpm (1 L/min), with a maximum operating pressure of 5000 psi (350 bar). It features an exceptionally fast response time of approximately 2 ms and allows for minimal leakage, with a maximum valve leakage at 110 SUS (24 cSt) being just 5 drops/min (0.3 cc/min). The adjustment mechanism includes up to five clockwise turns to increase the setting, with specific torque requirements: valve hex size is 7/8 in. (22.2 mm), installation torque ranges from 30 - 35 lbf ft (41 - 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 - 90 lbf in. (9 -10 Nm). The model weighs approximately .30 lb (.15 kg) and uses Viton seal kits identified as part number: 990010006.
