The Sun Hydraulics DRBOOSN (DRBOOSN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits, with one blocked port and two open ports. This versatile component can function independently or be used to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds a specific setting. With bidirectional flow paths between ports 2 and 3, as well as ports 1 and 2, the valve is highly adaptable for various applications. It features low internal leakage and minimal pilot flow consumption due to its direct-acting design. Additionally, it is interchangeable with pilot-operated versions, fitting the same cavities and offering identical flow paths. The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits. The valve incorporates Sun's floating style construction to minimize binding risks from installation torque or machining variations. The DRBOOSN fits cavity T21A, belongs to series 1, and has a capacity of up to 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). Its design includes an adjustment screw with an internal hex size of 5/32 inches (4 mm) and requires a locknut torque of 80\u201390 lbf-in (9\u201310 Nm). Weighing .55 lb (.25 kg), this model is compatible with Viton seal kits identified by part 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.
