The Sun Hydraulics RBAECEN (Material Number: RBAECEN) is a two-port, pilot-stage, direct-acting relief cartridge designed for pressure regulation in hydraulic systems. This fully adjustable, normally closed valve opens a flow path from port 1 to port 2 when the inlet pressure at port 1 surpasses the spring force setting. It utilizes the Sun T8A two-port cavity, making it an optimal choice for integration with Sun's main stage pilot or vent-to-operate cartridges. This design eliminates the need for separate pilot lines and requires only one cavity to accommodate both control and primary functions. The valve can handle pressures up to 5000 psi (350 bar) at ports 1 and 2. It features a hardened poppet and seat, ensuring consistent operation, low leakage rates, and superior wear characteristics. The backpressure at port 2 is directly additive to the pressure setting at port 1. The valve incorporates Sun's floating style construction to minimize internal binding due to excessive installation torque or machining variations. Cartridges with EPDM seals are suitable for systems using phosphate ester fluids but should not be exposed to petroleum-based fluids. The installation requires specific torque values: the main stage valve should be installed first, followed by the T8A pilot control section. Additional specifications include a capacity of 2.5 gpm (10 L/min), typical response time of 2 ms, maximum valve leakage of 15 drops/min (1 cc/min), and various hex sizes for installation and adjustment procedures. For applications requiring fast response times and robust performance in preventing overpressure scenarios, this direct-acting relief cartridge is highly effective.
