The Sun Hydraulics DRBOKSV (DRBOKSV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits, offering versatility in various hydraulic applications. This valve configuration features one blocked port and a bidirectional flow path between ports 2 and 3. It can be used independently 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 preset threshold, allowing it to modulate between two positions rather than being bistable. This capability makes it suitable for applications requiring variable control. Port 3 serves as a work port with a maximum pressure limit of 3000 psi (210 bar), primarily due to fatigue strength considerations rather than hydraulic operating limits. The DRBOKSV incorporates Sun's floating style construction, minimizing internal part binding risks caused by excessive installation torque or machining variations. It fits into T21A cavities and belongs to Series 1, with a capacity of handling up to 7 gpm (28 L/min) at factory pressure settings established at 4 gpm (15 L/min). The valve's maximum operating pressure reaches up to 5000 psi (350 bar), with minimal leakage under specific conditions\u2014up to 2 in\u00b3/min (30 cc/min) at 110 SUS (24 cSt). Adjustments are made via an internal hex screw, with clockwise turns increasing the setting up to a maximum of 5.5 turns. Installation requires a torque range of 30-35 lbf ft (41-47 Nm), while the locknut necessitates an additional torque of 80-90 lbf in (9-10 Nm). Weighing just .55 lb (0.25 kg), this compact cartridge valve is equipped with Viton seals for enhanced durability and performance in demanding environments.

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