The Sun Hydraulics RBAACBN (RBAACBN) is a direct-acting, pilot relief cartridge designed to remotely control the pressure setting of other pilot-operated valves. It is best utilized in conjunction with higher flow valves due to its capacity being limited to pilot flow. The main stage orifice is safeguarded by a 150-micron stainless steel screen, making it suitable for load-holding applications. Notably, back pressure on the tank port (port 2) directly adds to the valve setting at a 1:1 ratio. For systems using phosphate ester fluids, cartridges with EPDM seals are recommended, as exposure to petroleum-based fluids can damage these seals. The valve features W and Y controls that allow for full-range adjustability unless a special setting is specified. Corrosion-resistant options are available with external stainless steel or zinc-nickel plated components, identified by model code suffixes AP or LH respectively. This cartridge incorporates Sun\u2019s floating style construction, minimizing internal binding risks due to excessive installation torque or cavity-cartridge machining variations. It fits into Cavity T-3A and belongs to Series 2, with a capacity of 0.5 gpm (2 L/min) and a maximum operating pressure of 5000 psi (350 bar). Typical response time is approximately 2 ms, with maximum valve leakage at 110 SUS (24 cSt) being around 5 drops/min (0.3 cc/min). The valve's adjustment involves five clockwise turns to increase the setting and requires specific torque values for installation and locknut adjustments. With a weight of 0.50 lb (0.25 kg), it comes equipped with Viton seal kits for optimal performance in demanding environments.
