The Sun Hydraulics DRBOKAV (Material Number: DRBOKAV) 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 cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds its set threshold. Notably, port 3 can serve as a work port, with bidirectional flow paths between ports 2 and 3 and ports 1 and 2. Due to its direct-acting design, the DRBOKAV offers low internal leakage and minimal pilot flow consumption. It is interchangeable with pilot-operated versions, sharing the same cavities and flow paths, enhancing flexibility in application. The valve's construction incorporates Sun's floating style to mitigate issues related to internal part binding from excessive installation torque or machining variations. The DRBOKAV has a maximum operating pressure of 5000 psi (350 bar) and a capacity of 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min). It features an adjustment mechanism that increases settings with clockwise turns, with specific torque requirements for installation and locknut adjustments. This model is not bistable; it modulates between two positions as needed. Users should note that maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating constraints. The DRBOKAV is also equipped with Viton seals for durability in various environments.

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.
