The Sun Hydraulics DRBPOBN (DRBPOBN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It is engineered to switch when the pressure differential between port 1 and port 4 surpasses the set threshold. This valve can function independently or be used to actuate larger pilot-operated directional or logic cartridges. Notably, the flow path between ports 2 and 3 is bidirectional, as is the path between ports 1 and 2, offering versatile application possibilities. Port 3 can also serve as a work port, although its maximum pressure should be restricted to 3000 psi (210 bar) due to fatigue strength considerations. The DRBPOBN features low internal leakage and minimal pilot flow consumption because of its direct-acting design. It incorporates Sun's floating style construction, which helps prevent internal parts from binding due to excessive installation torque or variations in cavity/cartridge machining. The valve fits into a T21A cavity and belongs to Series 1 with a capacity of handling up to 7 gpm (28 L/min). The maximum operating pressure for this valve is set at 5000 psi (350 bar), with factory pressure settings established at a flow rate of 4 gpm (15 L/min). For adjustments, the valve allows up to five clockwise turns to increase settings, using an internal hex size adjustment screw of \\( \\frac{5}{32} \\) inch (4 mm). The locknut has a hex size of \\( \\frac{9}{16} \\) inch (15 mm) and should be torqued between 80-90 lbf-in (9-10 Nm). The valve's installation torque ranges from 30-35 lbf-ft (41-47 Nm), with a maximum leakage rate at 110 SUS (24 cSt) being just under two cubic inches per minute. The model weighs approximately .55 lb (.25 kg).

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.
