The Sun Hydraulics RBACQDV (RBACQDV) is a direct-acting, pilot relief cartridge designed for controlling the pressure setting of other pilot-operated valves. This component is ideal for systems where capacity is limited to pilot flow and should be used in conjunction with higher flow valves. It includes EPDM seals, suitable for use with phosphate ester fluids, but caution is advised as exposure to petroleum-based fluids can damage these seals. The main stage orifice features a 150-micron stainless steel screen, making it suitable for load holding applications. The valve's design allows back pressure on the tank port (port 2) to be directly additive to the valve setting at a 1:1 ratio. The RBACQDV can be specified with W and Y controls, adjustable throughout their full range unless a special setting is designated, which represents the maximum setting of the valve. It incorporates corrosion-resistant features with options for external stainless steel components or zinc-nickel plating, identified by model code suffixes AP or LH respectively. This cartridge employs Sun's floating style construction to reduce the risk of internal parts binding due to excessive installation torque or machining variations. The RBACQDV fits into Cavity T-10A Series 1 and has a capacity of 0.25 gpm (1 L/min) with a maximum operating pressure of 5000 psi (350 bar). The typical response time is approximately 2 ms, and maximum valve leakage at 110 SUS (24 cSt) is limited to five drops per minute (0.3 cc/min). Adjustment involves up to five clockwise turns to increase settings, and it features specific dimensions for hex sizes and installation torque requirements. Weighing only 0.30 lb (0.15 kg), this model also includes a Viton seal kit option under part number 990010006, ensuring robust performance in various hydraulic applications requiring precise pressure control.
