The Sun Hydraulics DRBOCWV (DRBOCWV) is a direct acting, 3-way directional cartridge valve designed for use in moderate flow circuits. This versatile valve can function independently or in conjunction with larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 surpasses the specified setting, offering bidirectional flow paths between ports 2 and 3, as well as ports 1 and 2. Port 3 serves as a work port with a maximum pressure limit of 3000 psi (210 bar) due to fatigue strength constraints. The valve's design minimizes internal leakage and pilot flow consumption, featuring Sun's floating style construction to reduce the risk of internal binding from excessive installation torque or machining variations. The DRBOCWV is interchangeable with other direct acting and pilot-operated valves, fitting the same cavities (T-21A) with consistent flow paths. This model has a capacity of 7 gpm (28 L/min) and operates at a maximum pressure of 5000 psi (350 bar). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with maximum valve leakage rated at 2 in\u00b3/min (30 cc/min). Adjustments to increase settings require approximately five clockwise turns. The valve's hex size measures .78 inches (22.2 mm), with an installation torque range of 30\u201335 lbf ft (41\u201347 Nm). The adjustment screw features an internal hex size of .532 inches (4 mm), while the locknut hex size is .916 inches (15 mm), requiring a torque of 80\u201390 lbf in (9\u201310 Nm). Weighing .55 lbs (.25 kg), this model includes Viton seal kits for optimal performance.

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.
