The Sun Hydraulics DRBOOEV (DRBOOEV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or be used to actuate larger pilot-operated directional cartridges or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 exceeds its set threshold. Port 3 serves as a work port, with bidirectional flow paths between ports 2 and 3, as well as ports 1 and 2. The valve's design ensures low internal leakage and minimal pilot flow consumption, making it efficient for various applications. This valve is interchangeable with pilot-operated versions, fitting the same cavities and maintaining identical flow paths. Notably, the pressure at port 4 directly adds to the valve's setting. The DRBOOEV is capable of modulating between two positions but is not bistable. It incorporates Sun's floating style construction to reduce risks of internal parts binding due to excessive installation torque or machining variations. The valve fits a T-21A cavity and belongs to Series 1 with a capacity of 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min). It supports a maximum operating pressure of 5000 psi (350 bar) while limiting maximum pressure at port 3 to 3000 psi (210 bar) due to fatigue strength considerations. The model features an adjustment mechanism with up to five clockwise turns to increase settings, requiring specific torque values for installation and locknut adjustments. The DRBOOEV weighs approximately .55 lb (0.25 kg) and uses Viton seal kits for durability in various operational environments.

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.
