The Sun Hydraulics RBAEKAV (RBAEKAV) is a two-port, pilot-stage, direct-acting relief cartridge designed for precise pressure regulation in hydraulic systems. This 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, effectively regulating system pressure. Utilizing the Sun T8A two-port cavity, it is ideal for integration with Sun's main stage pilot or vent-to-operate cartridges, eliminating the need for separate pilot lines and simplifying installation by requiring only one machined cavity for both control and primary functions. The valve supports pressures up to 5000 psi (350 bar) at both ports and features a hardened poppet and seat for consistent operation with low leakage rates and excellent wear resistance. Notably, backpressure at port 2 is directly additive to the pressure setting at port 1. The RBAEKAV incorporates Sun's floating style construction to reduce binding risks due to excessive torque or machining variations. It accommodates EPDM seals suitable for phosphate ester fluid systems but cautions against exposure to petroleum-based fluids which could damage the seals. With a capacity of 2.5 gpm (10 L/min), factory pressure settings are established at a flow rate of 30 cc/min, offering a typical response time of just 2 milliseconds. Installation specifics include a valve hex size of 7/8 inches (22.2 mm), an installation torque range of 20-25 lbf ft (27-33 Nm), and an adjustment screw internal hex size of 5/32 inches (4 mm). The locknut requires a hex size of 9/16 inches (15 mm) and torque between 80-90 lbf in (9-10 Nm). This cartridge is versatile in applications demanding rapid response and robust performance in direct-acting relief scenarios.

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.
