The Sun Hydraulics DRBOOWN (Material Number: DRBOOWN) 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. It operates by shifting when the pressure differential between port 1 and port 4 exceeds the valve's setting. Notably, port 3 can serve as a work port, and the flow paths between ports 2 and 3, as well as ports 1 and 2, are bidirectional. The valve's direct-acting design ensures low internal leakage and minimal pilot flow consumption. It features interchangeability with pilot-operated versions, sharing the same cavities and flow paths. The DRBOOWN incorporates Sun's floating style construction to reduce the risk of internal binding due to excessive torque or machining variations. The valve is capable of modulating between its two positions but is not bistable. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 7 gpm (28 L/min), it is suitable for various hydraulic applications while maintaining durability under high-pressure conditions. However, maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength considerations. Additional specifications include a cavity size of T-21A, series number 1, factory pressure settings established at 4 gpm (15 L/min), and a maximum valve leakage rate of 2 in\u00b3/min (30 cc/min). The adjustment mechanism allows for increased settings with up to five clockwise turns. The valve has a hex size of 7/8 inch (22.2 mm) for installation torque ranging from 30 to 35 lbf ft (41 to 47 Nm). The model weighs .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.
