The Sun Hydraulics DRBOOAV (DRBOOAV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or in conjunction with larger pilot-operated directional cartridges or logic cartridges. It shifts when the pressure differential between port 1 and port 4 surpasses the set threshold, with port 3 serving as a work port and allowing bidirectional flow between ports 2 and 3. The direct-acting design ensures low internal leakage and minimal pilot flow consumption, making it efficient for various applications. Direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities with identical flow paths. The DRBOOAV operates within a maximum pressure of 5000 psi (350 bar) and has a capacity of 7 gpm (28 L/min). It features Sun's floating style construction to reduce the risk of internal parts binding due to excessive installation torque or cavity/cartridge machining variations. The valve is not bistable but can modulate between two positions, with bidirectional flow capability between ports 1 and 2. The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits. Installation specifications include a valve hex size of 7/8 inch (22.2 mm), installation torque of 30-35 lbf ft (41-47 Nm), an adjustment screw internal hex size of 5/32 inch (4 mm), locknut hex size of 9/16 inch (15 mm), and locknut torque ranging from 80-90 lbf in (9-10 Nm). The model weighs approximately .55 lb (.25 kg) and comes with a Viton seal kit under material number 990021006.

Direct-acting, 3-way directional cartridges (1 blocked, 2 to 3 open) 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 4 exceeds the setting.
- Port 3 can be used as a work port.
- The flow path between port 2 and port 3 is bidirectional.
- 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.
- Pressure at port 4 is directly additive to the setting of the valve.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- The flow path between port 1 and port 2 is bidirectional.
- Maximum pressure at port 3 should be limited to 3000 psi (210 bar). This is due to fatigue strength limits not hydraulic operating limits.
- 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.
