The Sun Hydraulics RBACFBV (Material Number: RBACFBV) is a direct-acting pilot relief cartridge designed for precise pressure control in hydraulic systems. These cartridges are primarily used to remotely control the pressure setting of other pilot-operated valves, making them suitable for applications requiring load holding capabilities. The valve's design incorporates a 150-micron stainless steel screen to protect the main stage orifice and features corrosion-resistant options identified by model code suffixes AP or LH. The RBACFBV is configured with EPDM seals, specifically for use with phosphate ester fluids, as exposure to petroleum-based fluids can damage the seals. This cartridge operates within a cavity T-10A and has a 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 maximum valve leakage at 110 SUS (24 cSt) of 5 drops/min (0.3 cc/min). The valve is adjustable throughout its range using W or Y controls, unless specified otherwise with a special setting. Installation requires a torque of 30-35 lbf ft (41-47 Nm), and it features an internal hex size for adjustment screw at 5/32 in. (4 mm). The RBACFBV's robust construction includes Sun\u2019s floating style design to minimize binding due to installation torque variations, ensuring stability and reliability under various conditions. It is ideal for systems requiring fast response times and dirt-tolerant operations, such as those found in agricultural machinery like portable grain augers where rapid pressure adjustments are critical for safety and efficiency.
