The Sun Hydraulics DRBOOEN (Material Number: DRBOOEN) is a versatile direct-acting, 3-way directional cartridge valve. It functions as a switching device in moderate flow circuits and can be used independently or to actuate larger pilot-operated directional or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 exceeds the set threshold. With a bidirectional flow path between ports 2 and 3, port 3 can also serve as a work port. The design ensures low internal leakage and minimal pilot flow consumption, making it efficient for various applications. This model is interchangeable with pilot-operated versions, fitting the same cavities and maintaining identical flow paths. Notably, it is not bistable but can modulate between two positions. The maximum pressure at port 3 should be limited to 3000 psi due to fatigue strength constraints. It features Sun's floating style construction, minimizing internal binding risks from installation torque or machining variations. Key specifications include a T-21A cavity, Series 1 capacity of 7 gpm (28 L/min), maximum operating pressure of 5000 psi (350 bar), and a factory pressure setting established at 4 gpm (15 L/min). The valve's hex size is .78 inches (22.2 mm) with an installation torque range of 30-35 lbf ft (41-47 Nm). Additionally, the adjustment screw has an internal hex size of .156 inches (4 mm) with a locknut hex size of .562 inches (15 mm) requiring a torque of 80-90 lbf in (9-10 Nm). The model weighs approximately .55 lb (.25 kg) and uses Viton seal kit number 990021006 for maintenance or replacement 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.
