The Sun Hydraulics DRBOOBN (DRBOOBN) is a direct-acting, 3-way directional cartridge valve designed for use in moderate flow circuits. This versatile component can function independently or be utilized to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses the set threshold, with port 3 serving as a potential work port. Notably, the flow paths between ports 2 and 3, as well as ports 1 and 2, are bidirectional, allowing for flexible application in various circuit configurations. The DRBOOBN is engineered with low internal leakage and minimal pilot flow consumption due to its direct-acting design. It is interchangeable with pilot-operated versions, sharing cavity compatibility and flow paths. The valve incorporates Sun's floating style construction to mitigate internal part binding caused by excessive installation torque or machining variations. It features a maximum operating pressure of 5000 psi (350 bar) and has a capacity of handling up to 7 gpm (28 L/min). Pressure at port 4 directly adds to the valve setting, while the maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength limits. The DRBOOBN is not bistable but can modulate between two positions as needed. Installation requires specific torque settings: valve hex size of .78 inches (22.2 mm), installation torque of 30-35 lbf ft (41-47 Nm), adjustment screw internal hex size of .532 inches (4 mm), locknut hex size of .916 inches (15 mm), and locknut torque of 80-90 lbf in (9-10 Nm). The model weighs approximately .55 lb (.25 kg) and includes a Viton seal kit under part number 990021006 for maintenance needs.

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.
