The Sun Hydraulics DRBPOEN (DRBPOEN) 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 the set threshold. The valve features a bidirectional flow path between ports 2 and 3, and between ports 1 and 2, providing flexibility in circuit design. Port 3 serves as a work port, with a maximum allowable pressure of 3000 psi (210 bar) due to fatigue strength limits. The DRBPOEN incorporates Sun's floating style construction to minimize the risk of internal binding caused by excessive installation torque or cavity/cartridge machining variations. It offers low internal leakage and minimal pilot flow consumption, thanks to its direct-acting design. This model is not bistable but can modulate between two positions as needed. With a cavity size of T-21A and series number 1, the valve has a capacity of up to 7 gpm (28 L/min), with factory pressure settings established at 4 gpm (15 L/min). It can handle a maximum operating pressure of up to 5000 psi (350 bar). The valve's adjustment features include an internal hex screw for setting changes, requiring up to five clockwise turns for increasing settings. The installation requires specific torque values for both the valve itself and its locknut. The DRBPOEN is compact with a model weight of .55 lb (0.25 kg) and utilizes Viton seals, making it suitable for various hydraulic applications where reliable performance and adaptability are critical.

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.
