The Sun Hydraulics DRBPOSV (DRBPOSV) is a versatile direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This model allows for a 1 to 2 open configuration with port 3 blocked, making it ideal for applications requiring precise control of fluid direction. The valve is engineered to shift when the pressure differential between port 1 and port 4 exceeds a preset value, with pressure at port 4 directly influencing the setting. Notably, the flow paths between ports 1 and 2, as well as ports 2 and 3, are bidirectional. With a maximum operating pressure of up to 5000 psi (350 bar), this valve is robust enough for demanding environments while maintaining low internal leakage and pilot flow consumption due to its direct-acting design. The DRBPOSV can be used independently or in conjunction with larger pilot-operated directional or logic cartridges. It features Sun's floating style construction, which minimizes the risk of internal binding caused by excessive installation torque or machining variations in cavity/cartridge interfaces. The valve fits into a T21A cavity and offers 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). Installation requires specific torques: valve installation torque ranges from 30 to 35 lbf ft (41 to 47 Nm), while locknut torque ranges from 80 to 90 lbf in (9 to 10 Nm). The adjustment screw has an internal hex size of ^5\u204432 in. (4 mm) and allows for fine-tuning via clockwise turns. This model weighs approximately .55 lb (0.25 kg) and utilizes Viton seal kits for enhanced 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.
