The Sun Hydraulics DRBAOSN (DRBAOSN) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It functions as a switching device and can be used independently or to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses the preset value. With a maximum operating pressure of 5000 psi (350 bar), this valve features low internal leakage and minimal pilot flow consumption due to its direct-acting design. It is capable of modulating between two positions and is not bistable, making it suitable for applications requiring precise control. The DRBAOSN incorporates Sun's floating style construction, which reduces the risk of internal parts binding from excessive installation torque or machining variations. This valve fits into T-11A cavities and offers a capacity of 7 gpm (28 L/min), with factory pressure settings established at 4 gpm (15 L/min). The valve's adjustment involves up to 5.5 clockwise turns to increase the setting, with a valve hex size of 7/8 inch (22.2 mm) and an installation torque range of 30-35 lbf ft (41-47 Nm). For users needing alternative configurations, direct-acting and pilot-operated versions are interchangeable within the same cavities and flow paths. The DRBAOSN is particularly suited for applications where low pilot flow consumption is critical, offering flexibility in various hydraulic circuit designs while maintaining robust performance under high-pressure conditions.

Normally open, direct-acting, 2-way directional cartridges are switching devices typically used in moderate flow circuits. They can be used by themselves or to actuate larger pilot-operated directional cartridges or logic cartridges. The valve shifts when the pressure differential between port 1 and port 3 exceeds the setting.
- Pressure at port 3 is directly additive to the setting of the valve. Because of this, port 3 may not be useable as a work port in your circuit. If this is a consideration, the 4 port version of this valve may be a solution.
- Because of their direct-acting design, these cartridges feature low internal leakage and low pilot flow consumption.
- Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- 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.
