The Sun Hydraulics DRBPOAV (DRBPOAV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It features a 1 to 2 open and 3 blocked configuration, making it suitable for independent use or for actuating larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds its set value. Port 3 can function as a work port with bidirectional flow between ports 2 and 3, while the flow path between ports 1 and 2 is also bidirectional. This cartridge valve boasts low internal leakage and minimal pilot flow consumption due to its direct-acting design. It is interchangeable with pilot-operated versions, sharing the same cavity fit and flow paths. The DRBPOAV incorporates Sun Hydraulics' floating style construction to minimize internal part binding caused by excessive installation torque or machining variations in the cavity/cartridge interface. The valve's maximum operating pressure reaches up to 5000 psi (350 bar), while port 3 should be limited to a maximum pressure of 3000 psi (210 bar) due to fatigue strength considerations. This model supports a capacity of up to 7 gpm (28 L/min) with factory pressure settings established at a flow rate of 4 gpm (15 L/min). Additional specifications include an adjustable setting mechanism with up to five clockwise turns, a valve hex size of .78 inches (22.2 mm), and installation torque ranging from 30 to 35 lbf ft (41 to 47 Nm). The DRBPOAV's compact design weighs approximately .55 lb (0.25 kg) and utilizes Viton seal kits for optimal performance in hydraulic systems requiring precise modulation capabilities without bistability concerns.

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.
