The Sun Hydraulics RBAEYDN (RBAEYDN) is a two-port, pilot-stage, direct-acting relief cartridge designed for pressure regulation in hydraulic systems. This fully adjustable valve remains normally closed until the inlet pressure at port 1 exceeds the preset spring force, allowing flow to port 2. The valve features the Sun T-8A 2-port cavity, making it an optimal choice for integration with Sun's main stage pilot or vent-to-operate cartridges. This design eliminates separate pilot lines and requires only one machined cavity for both control and primary functions. The valve can handle pressures up to 5000 psi (350 bar) at both ports and incorporates hardened poppet and seat components for consistent operation, low leakage rates, and enhanced wear resistance. Backpressure at port 2 is directly added to the pressure setting at port 1. The RBAEYDN employs Sun's floating style construction to reduce internal binding due to excessive installation torque or machining variations. It features a maximum flow capacity of 2.5 gpm (10 L/min) and a typical response time of 2 milliseconds. The valve is designed for minimal leakage, with a maximum of 15 drops per minute at standard fluid viscosities. Installation requires specific torque settings: the main stage should be torqued first followed by the T-8A pilot control section. This cartridge is compatible with systems using phosphate ester fluids when configured with EPDM seals but should not be exposed to petroleum-based fluids as they may damage the seals. The RBAEYDN is suitable for applications requiring rapid response and precise pressure control in hydraulic circuits where space efficiency is crucial due to its integrated design capabilities.

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.
