The Sun Hydraulics DRBPKDN (DRBPKDN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 surpasses the set threshold. The valve offers bidirectional flow paths between ports 1 and 2, and ports 2 and 3, with port 3 also serving as a work port. Its direct-acting design ensures low internal leakage and minimal pilot flow consumption, making it an efficient choice for various applications. The valve is not bistable and can modulate between its two positions. The DRBPKDN is interchangeable with pilot-operated versions, fitting the same cavities and maintaining consistent flow paths. It features Sun's floating style construction to reduce the risk of internal binding due to installation torque variations or machining discrepancies. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 7 gpm (28 L/min), this valve is robust enough for demanding environments while maintaining a maximum valve leakage of just 2 in\u00b3/min (30 cc/min). Its installation requires specific torque settings: the valve hex size is 7/8 inch (22.2 mm), with an installation torque of 30-35 lbf\u00b7ft (41-47 Nm). The adjustment screw has an internal hex size of 5/32 inch (4 mm), while the locknut hex size is 9/16 inch (15 mm), requiring a torque of 80-90 lbf\u00b7in (9-10 Nm). The model weighs .55 lb (.25 kg) and uses a Viton seal kit with part number 990021006 for effective sealing solutions in hydraulic systems.

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.
