The Sun Hydraulics DRBOCBV (DRBOCBV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It is capable of switching between two positions with one port blocked and the flow path open between ports 2 and 3, which is bidirectional. This valve can be utilized independently or to actuate larger pilot-operated directional cartridges or logic cartridges. The DRBOCBV shifts when the pressure differential between port 1 and port 4 exceeds its setting, with pressure at port 4 being directly additive to the valve's setting. Port 3 can function as a work port, but its maximum pressure should be limited to 3000 psi (210 bar) due to fatigue strength limits. Featuring low internal leakage and low pilot flow consumption thanks to its direct-acting design, this cartridge valve incorporates Sun's floating style construction, minimizing internal part binding risks due to excessive installation torque or machining variations. The DRBOCBV fits T21A cavities and is interchangeable with both direct-acting and pilot-operated versions, sharing the same flow paths. It has a capacity of 7 gpm (28 L/min) with factory pressure settings established at 4 gpm (15 L/min). The maximum operating pressure of this model reaches up to 5000 psi (350 bar), with a maximum valve leakage of 2 in\u00b3/min (30 cc/min) at 110 SUS (24 cSt). Adjustments can be made via an internal hex screw, requiring up to five full clockwise turns for increased settings. Installation requires a torque of 30-35 lbf ft (41-47 Nm), while the locknut should be torqued between 80-90 lbf in (9-10 Nm). Weighing .55 lb (.25 kg), this model is compatible with Viton seal kits for maintenance purposes.

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.
