The Sun Hydraulics RBAEOAV (RBAEOAV) is a two-port, pilot-stage, direct-acting relief cartridge that functions as a fully adjustable, normally closed pressure regulating valve. Its primary application is to manage pressure by opening a flow path from port 1 to port 2 when the inlet pressure at port 1 surpasses the spring force setting of the valve. This cartridge is designed for use with Sun's main stage pilot or vent-to-operate cartridges and utilizes the T8A two-port cavity, allowing for streamlined installation by eliminating separate pilot lines and requiring only one machined cavity for both control and primary functions. The valve operates effectively up to a maximum pressure of 5000 psi (350 bar) at both ports, making it suitable for high-pressure applications. The RBAEOAV features hardened poppet and seat components which ensure consistent operation, minimal leakage rates, and enhanced wear resistance. The design incorporates Sun's floating style construction to reduce risks of internal binding due to excessive torque or machining variations. It also accommodates systems with phosphate ester fluids when configured with EPDM seals but warns against exposure to petroleum-based substances which can damage these seals. Specifications include a capacity of 2.5 gpm (10 L/min), factory pressure settings established at 2 in\u00b3/min (30 cc/min), typical response time of 2 ms, and maximum leakage rate of 15 drops/min (1 cc/min). Installation requires specific torque values: the main stage valve should be torqued first followed by the T8A pilot control section. The valve hex size is 7/8 in. (22.2 mm) with an installation torque range of 20 - 25 lbf\u00b7ft (27 - 33 Nm). Additionally, it includes an internal hex adjustment screw size of 5/32 in. (4 mm) and a locknut hex size of 9/16 in. (15 mm), requiring locknut torque between 80 - 90 lbf\u00b7in (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.
