The Sun Hydraulics DRBPKDV (DRBPKDV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It features a configuration where port 1 to port 2 is open and port 3 is blocked, making it suitable for applications requiring precise switching control. This valve can be utilized 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 surpasses the set threshold, with port 3 serving as a work port if needed. Notably, the flow paths between ports 2 and 3, as well as ports 1 and 2, are bidirectional. The DRBPKDV offers low internal leakage and minimal pilot flow consumption due to its direct-acting design. It shares compatibility with pilot-operated versions in terms of cavity fit and flow paths, enhancing versatility in system integration. The maximum pressure permissible at port 3 is capped at 3000 psi (210 bar) because of fatigue strength limits rather than hydraulic operating constraints. The valve also incorporates Sun's floating style construction to reduce the risk of internal part binding from excessive installation torque or machining variations. With a capacity of up to 7 gpm (28 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve ensures reliable performance under demanding conditions. Factory pressure settings are established at a flow rate of 4 gpm (15 L/min). For adjustments, users can increase settings with up to five clockwise turns using an internal hex screw sized at \\(\\frac{5}{32}\\) inches (4 mm). The locknut requires a torque setting between 80-90 lbf-in (9-10 Nm). The DRBPKDV model weighs approximately .55 lb (.25 kg) and uses Viton seal kits for enhanced durability in various hydraulic applications.

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.
