The Sun Hydraulics DRBOCEV (Material Number: DRBOCEV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This valve is versatile, functioning as a standalone device or to actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 surpasses the pre-set threshold. Port 3 serves as a work port, with bidirectional flow paths between ports 2 and 3 and ports 1 and 2. Constructed with Sun's floating style design, it minimizes internal part binding due to excessive installation torque or machining variations. The DRBOCEV is not bistable, allowing it to modulate between two positions. The valve's maximum operating pressure is rated at 5000 psi (350 bar), with a maximum capacity of 7 gpm (28 L/min). It features low internal leakage and pilot flow consumption due to its direct-acting design. The valve fits into T21A cavities and is interchangeable with pilot-operated versions, sharing the same flow paths. Pressure at port 4 directly adds to the valve setting, while maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength limits. Additional specifications include a factory pressure setting established at a flow rate of 4 gpm (15 L/min), a maximum valve leakage of 2 in\u00b3/min (30 cc/min) at 110 SUS (24 cSt), and an adjustment range facilitated by up to five clockwise turns. The DRBOCEV's hex size for installation is .78 inches (22.2 mm), requiring an installation torque of 30-35 lbf\u00b7ft (41-47 Nm). The adjustment screw internal hex size is .532 inches (4 mm), complemented by a locknut hex size of .916 inches (15 mm) with a locknut torque specification of 80-90 lbf\u00b7in (9-10 Nm). The model weighs .55 lb (.25 kg) and utilizes Viton seal kits for reliability in various applications.

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.
