The Sun Hydraulics RBACJEN (RBACJEN) is a direct-acting, pilot relief cartridge designed for remote control of pressure settings in pilot-operated valves. This component is ideal for load holding applications and should be paired with higher flow valves due to its capacity being limited to pilot flow. The valve's main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability in operation. It's particularly suitable for systems utilizing phosphate ester fluids, as cartridges with EPDM seals are specifically designed for such use; exposure to petroleum-based fluids can damage these seals. The RBACJEN model features corrosion-resistant options, identifiable by the suffixes AP or LH in the model code, indicating external stainless steel or zinc-nickel plated components, respectively. It incorporates Sun\u2019s floating style construction to prevent internal parts from binding due to excessive installation torque or machining variations. This valve allows back pressure on the tank port (port 2) that directly adds to the valve setting at a 1:1 ratio. For adjustments, it offers W and Y controls that can be specified with or without a special setting. The valve is adjustable throughout its full range unless a special setting is specified, which then represents the maximum setting. The RBACJEN supports a maximum operating pressure of 5000 psi (350 bar) and has a typical response time of 2 ms. It maintains minimal leakage at standard conditions, making it both efficient and reliable for various applications requiring precise pressure control.
