The Sun Hydraulics DRBOKDV (Material Number: DRBOKDV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It functions as a switching device, offering versatility by either operating independently or actuating larger pilot-operated directional or logic cartridges. This valve shifts when the pressure differential between port 1 and port 4 exceeds the set threshold, with port 3 serving as a work port and allowing bidirectional flow between ports 2 and 3. Its direct-acting design ensures low internal leakage and minimal pilot flow consumption, making it efficient in operation. The DRBOKDV is interchangeable with pilot-operated versions, fitting the same cavities and maintaining identical flow paths. Notably, pressure at port 4 directly adds to the valve's setting. The valve is not bistable but can modulate between two positions, with bidirectional flow possible between ports 1 and 2. It has a maximum operating pressure of 5000 psi (350 bar) and limits maximum pressure at port 3 to 3000 psi (210 bar) due to fatigue strength considerations. Featuring Sun's floating style construction, this valve minimizes internal part binding risks from excessive installation torque or cavity/cartridge machining variations. With a capacity of 7 gpm (28 L/min), factory pressure settings are established at a flow rate of 4 gpm (15 L/min). The DRBOKDV includes specifications such as a T21A cavity type, series number one, and adjustment capabilities with up to five clockwise turns to increase settings. It requires specific installation torque values for both the valve itself (30-35 lbf ft/41-47 Nm) and its locknut (80-90 lbf in/9-10 Nm). The model weighs .55 lb (.25 kg) and uses Viton seals under seal kit 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.
