The Sun Hydraulics RBAAFAV (RBAAFAV) is a direct-acting, pilot relief cartridge designed for remote pressure control in conjunction with other pilot-operated valves. This model is specifically built for load-holding applications and features a main stage orifice protected by a 150-micron stainless steel screen. The valve's capacity is limited to pilot flow, making it essential to pair with higher flow valves for optimal performance. Notably, back pressure on the tank port (port 2) directly adds to the valve setting at a 1:1 ratio. For systems utilizing phosphate ester fluids, cartridges with EPDM seals are recommended; however, these seals are not compatible with petroleum-based fluids. The RBAAFAV model can incorporate corrosion-resistant components, identifiable by suffixes AP or LH in its model code, suitable for corrosive environments. It utilizes Sun's floating style construction to reduce the risk of internal binding due to installation torque or machining variations. The cartridge fits into Cavity T-3A and belongs to Series 2, with a flow capacity of 0.5 gpm (2 L/min) and can operate at pressures up to 5000 psi (350 bar). It exhibits a typical response time of 2 milliseconds and has minimal leakage at maximum settings\u20145 drops per minute (0.3 cc/min). Adjustment of the valve setting requires up to five clockwise turns, facilitated through an internal hex adjustment screw size of 5/32 inches (4 mm). Installation torque ranges between 45-50 lbf ft (61-68 Nm), while locknut torque should be maintained between 80-90 lbf in (9-10 Nm). The unit weighs approximately 0.50 lb (0.25 kg), and it is compatible with Viton seal kits under part number 990203006.
