The Sun Hydraulics DRBOKEN (DRBOKEN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or be used to actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 surpasses a predetermined setting. The valve features bidirectional flow paths between ports 2 and 3, as well as ports 1 and 2, providing flexibility in circuit design. Port 3 can also serve as a work port, although its maximum pressure should not exceed 3000 psi due to fatigue strength limits. One of the key advantages of this valve is its low internal leakage and minimal pilot flow consumption, attributed to its direct-acting design. Additionally, this model incorporates Sun's floating style construction, which minimizes the risk of internal parts binding from excessive installation torque or machining variations in cavity/cartridge interfaces. The DRBOKEN is interchangeable with other direct-acting and pilot-operated valves from Sun Hydraulics, fitting the same cavities and maintaining consistent flow paths. The valve's capacity is rated at 7 gpm (28 L/min), with factory pressure settings established at a flow rate of 4 gpm (15 L/min). It can withstand a maximum operating pressure of up to 5000 psi (350 bar). The model includes an adjustment screw with an internal hex size of 5/32 inch (4 mm) and requires specific installation torques for both the valve body and locknut. Weighing just .55 lb (0.25 kg), it offers robust performance in a compact form factor.

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.
