The Sun Hydraulics DRBPOBV (Material Number: DRBPOBV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It features a configuration where ports 1 to 2 are open and port 3 is blocked. This valve is versatile, being suitable for standalone applications or for actuating larger pilot-operated directional cartridges or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 exceeds the set threshold, with pressure at port 4 directly adding to the valve setting. Port 3 can function as a work port, and the flow path between ports 2 and 3 is bidirectional. With low internal leakage and pilot flow consumption due to its direct-acting design, this valve offers efficiency in operation. It shares interchangeable cavities and flow paths with pilot-operated versions, providing flexibility in application. The DRBPOBV has a cavity size of T-21A, belongs to Series 1, and has a capacity of handling up to 7 gallons per minute (28 liters per minute). It operates at a maximum pressure of 5000 psi (350 bar), while maintaining maximum valve leakage at minimal levels of up to 2 cubic inches per minute (30 cc/min) at oil viscosity of 110 SUS (24 cSt). The cartridge construction employs Sun's floating style design to minimize internal binding risks due to installation torque or machining variations. The installation torque ranges from 30 to 35 lbf-ft (41 to 47 Nm), with an adjustment screw internal hex size of 5/32 inch (4 mm). The model weighs approximately .55 lb (.25 kg) and utilizes Viton seal kits for durability.

Direct-acting, 3-way directional cartridges (1 to 2 open, 3 blocked) 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.
