The Sun Hydraulics RBAAJWN (RBAAJWN) is a direct-acting, pilot relief cartridge designed to remotely control the pressure setting of other pilot-operated valves. This model is engineered for use in load-holding applications, offering a capacity of 0.5 gpm (2 L/min) and a maximum operating pressure of 5000 psi (350 bar). The valve's main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability in its operation. It incorporates Sun's floating style construction to minimize the risk of internal parts binding due to excessive installation torque or machining variations. The RBAAJWN model is suitable for systems utilizing phosphate ester fluids when equipped with EPDM seals; however, exposure to petroleum-based fluids can damage these seals. The valve's back pressure on the tank port is directly additive to the valve setting at a 1:1 ratio. It features adjustable settings throughout its full range using W or Y controls unless specified otherwise with a special setting. This cartridge valve is also designed for corrosive environments and can be configured with external stainless steel components (suffix AP) or external zinc-nickel plated components (suffix LH). Additional specifications include a typical response time of 2 ms, maximum valve leakage at 110 SUS (24 cSt) of 5 drops/min (0.3 cc/min), and adjustment capabilities through five clockwise turns to increase the setting. Installation requires a torque of 45-50 lbf ft (61-68 Nm), and it includes an internal hex size adjustment screw of 5/32 in. (4 mm). Overall, the Sun Hydraulics RBAAJWN offers robust performance in controlling pressure settings with precision and reliability, making it ideal for applications requiring stable and fast response under varying conditions.
