The Sun Hydraulics DRBAOBN (DRBAOBN) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It is versatile 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 exceeds its set value, with pressure at port 3 being directly additive to the setting. This characteristic may limit its use as a work port in certain circuits, for which a 4-port version may be more suitable. The DRBAOBN features low internal leakage and minimal pilot flow consumption due to its direct-acting design. It is interchangeable with pilot-operated versions, sharing the same cavities and flow paths but differing in their operational characteristics; direct-acting valves are preferred for their speed and robustness, while pilot-operated valves offer ease of adjustment and lower pressure rise versus flow curves. This valve incorporates Sun's floating style construction to reduce the risk of internal parts binding from excessive installation torque or machining variations. It fits into cavity T-11A, belongs to series 1, and has a capacity of 7 gpm (28 L/min). The factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). The maximum valve leakage at 110 SUS (24 cSt) is limited to 2 in\u00b3/min (30 cc/min). The adjustment mechanism requires up to five clockwise turns to increase the setting, with specific torque requirements for installation and adjustments provided for optimal performance. The model weighs approximately .60 lb (.30 kg) and comes with a Viton seal kit option available under part number 990011006.

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.
