The Sun Hydraulics RBAELEE (RBAELEE) is a two-port, pilot-stage, direct-acting relief cartridge that is fully adjustable and functions as a normally closed pressure regulating valve. It is designed to open a flow path from port 1 to port 2 tank when the inlet pressure at port 1 exceeds the spring force valve setting. This cartridge 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. A key advantage of this design is the elimination of separate pilot lines, requiring only one cavity to be machined for both control and primary functions. The cartridge supports pressures up to 5000 psi (350 bar) at ports 1 and 2, with a capacity of 2.5 gpm (10 L/min). Its hardened poppet and seat ensure consistent operation with low leakage rates and superior wear characteristics. The RBAELEE features Sun's floating style construction, minimizing internal part binding due to installation torque or machining variations. The cartridge's response time is typically around 2 ms, with maximum leakage at 110 SUS (24 cSt) rated at 15 drops/min (1 cc/min). It includes an internal hex adjustment screw size of 5/32 in. (4 mm) and requires specific installation torques for both the valve body and locknut. Additionally, cartridges configured with EPDM seals are intended for systems using phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. This product is suitable for applications requiring fast response times and robust performance in pressure regulation tasks. It is particularly useful in preventing overpressure scenarios in hydraulic systems while maintaining ease of adjustability and dirt tolerance.

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.
