The Sun Hydraulics DRBOCDN (Material Number: DRBOCDN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It functions as a switching device with one blocked port and open flow between ports 2 and 3. This valve can be used independently or to actuate larger pilot-operated directional or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 exceeds the set value, with pressure at port 4 being directly additive to this setting. Notably, the flow path between ports 1 and 2, as well as between ports 2 and 3, is bidirectional. Port 3 can also serve as a work port, although its maximum pressure should be limited to 3000 psi (210 bar) due to fatigue strength limits. The DRBOCDN features low internal leakage and pilot flow consumption due to its direct-acting design. It is capable of modulating between two positions rather than being bistable. The valve incorporates Sun's floating style construction, minimizing the risk of internal binding from excessive installation torque or machining variations. Its cavity type is T21A, belonging to Series 1 with a capacity of up to 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with a maximum operating pressure of up to 5000 psi (350 bar). Additional specifications include a maximum valve leakage rate of 2 in\u00b3/min (30 cc/min) at an oil viscosity of 110 SUS (24 cSt), and it features an adjustment range that can be increased by turning clockwise up to five full turns. The valve's hex size measures at .78 inches (22.2 mm), with installation torque requirements ranging from 30-35 lbf-ft (41-47 Nm). The adjustment screw has an internal hex size of .156 inches (4 mm), while the locknut requires a hex size of .5625 inches (15 mm) and torque between 80-90 lbf-in (9-10 Nm). The model weighs approximately .55 lbs (.25 kg) and uses Viton seal kits under part 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.
