The Sun Hydraulics RBAECBV (RBAECBV) is a two-port, pilot-stage, direct-acting relief cartridge designed for precise pressure regulation in hydraulic systems. This normally closed valve is fully adjustable and operates by opening a flow path from port 1 to port 2 when the inlet pressure at port 1 surpasses the set spring force. It utilizes the Sun T8A two-port cavity, making it an ideal choice for integration with Sun's main stage pilot or vent-to-operate cartridges without needing separate pilot lines. The valve can handle pressures up to 5000 psi (350 bar) at both ports and features hardened poppet and seat components for consistent operation, low leakage rates, and high wear resistance. The backpressure at port 2 directly adds to the pressure setting at port 1, ensuring reliable performance under varying conditions. This cartridge is particularly suited for applications requiring quick response times, with a typical reaction time of just 2 milliseconds. It has a maximum flow capacity of 2.5 gpm (10 L/min) and exhibits minimal leakage rates of up to 15 drops/min (1 cc/min) at standard viscosity levels. Installation requires specific torque values: the main stage valve should be torqued first, followed by the T8A pilot control section. The valve's design incorporates Sun's floating style construction to minimize internal binding risks due to installation torque or machining variations. The RBAECBV is compatible with EPDM seals for phosphate ester fluid systems but should avoid exposure to petroleum-based fluids. For installation, it features a valve hex size of 7/8 inch (22.2 mm), an adjustment screw internal hex size of 5/32 inch (4 mm), and requires specific locknut torque settings ranging from 80-90 lbf-in (9-10 Nm).

Two-port, pilot-stage, direct-acting relief cartridges are fully adjustable, normally closed pressure regulating valves. When the pressure at port 1 (inlet) is sufficient to overcome the spring force (valve setting), a flow path is opened from port 1 to port 2 (tank).
- Utilizes the Sun T-8A 2-port cavity making it the ideal choice to use in conjunction with Sun's main stage pilot or vent-to-operate cartridges. Separate pilot lines are eliminated and only one cavity needs to be machined to accommodate both the control and primary function. Note: All 2-position, 2-way pilot stage control cartridges utilize the same cavity and are physically interchangeable. Functionality is the only consideration.
- Note: The main stage valve should first be installed to the correct torque value followed by the T-8A pilot control section into the main stage valve to its required torque value.
- Ports 1 and 2 may be pressured to 5000 psi (350 bar).
- Hardened poppet and seat provide consistent operation, low leakage rates and superior wear characteristics.
- Backpressure at port 2 (outlet) is directly additive to the pressure setting at port 1 (inlet).
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
