The Sun Hydraulics DRBAOBV (DRBAOBV) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It can function independently or be used to actuate larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 exceeds the set value, with pressure at port 3 being directly additive to the setting. This design consideration means that port 3 might not be suitable as a work port in some circuits; in such cases, a 4-port version of this valve could be more appropriate. The DRBAOBV features low internal leakage and minimal pilot flow consumption due to its direct-acting design. It is capable of modulating between two positions but is not bistable. The valve incorporates Sun's floating style construction, minimizing the risk of internal parts binding due to excessive installation torque or cavity/cartridge machining variations. Key specifications include a T-11A cavity, series 1 classification, with a capacity of 7 gpm (28 L/min), and factory pressure settings established at 4 gpm (15 L/min). It supports a maximum operating pressure of up to 5000 psi (350 bar) and exhibits maximum valve leakage at 110 SUS (24 cSt) of about 2 in\u00b3/min (30 cc/min). The adjustment screw requires five full clockwise turns to increase the setting, with specified torque requirements for installation and locknut adjustments. The model weighs approximately .60 lb (.30 kg) and utilizes Viton seal kits for maintenance.

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.
