The Sun Hydraulics DRBOKAN (Material Number: DRBOKAN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can be utilized independently or 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 predetermined setting. Notably, port 3 can serve as a work port with bidirectional flow capability between ports 2 and 3. Thanks to its direct-acting design, the DRBOKAN valve boasts low internal leakage and minimal pilot flow consumption. It is interchangeable with pilot-operated versions, fitting the same cavities and providing identical flow paths. The valve incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations. It is capable of modulating between two positions rather than being bistable. The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits, although the maximum operating pressure for the valve itself is rated at 5000 psi (350 bar). The valve features a capacity of up to 7 gpm (28 L/min) with factory pressure settings established at 4 gpm (15 L/min). Additional specifications include a cavity size of T-21A, series designation of 1, and a maximum leakage rate of 2 in\u00b3/min (30 cc/min) at 110 SUS (24 cSt). Adjustments can be made by turning clockwise up to five turns, with specific hex sizes for various components such as the valve hex size of .78 in. (22.2 mm), an adjustment screw internal hex size of .15625 in. (4 mm), and locknut hex size of .5625 in. (15 mm). The model weighs approximately .55 lb (.25 kg) and utilizes Viton seal kits for optimal performance.

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.
