The Sun Hydraulics DRBPKEN (DRBPKEN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It functions by switching the flow between ports 1 and 2 while blocking port 3, with the valve shifting when the pressure differential between port 1 and port 4 exceeds the set value. This valve is versatile, capable of being used independently or to actuate larger pilot-operated directional or logic cartridges. It features bidirectional flow paths between ports 1 and 2, as well as ports 2 and 3. Notably, this valve is not bistable; it can modulate between its two positions based on system demands. The DRBPKEN incorporates Sun's floating style construction to reduce internal part binding due to installation torque or machining variations. It fits into a T-21A cavity and has a series capacity of up to 7 gpm (28 L/min), with factory pressure settings established at a flow rate of 4 gpm (15 L/min). The maximum operating pressure for this model is rated at an impressive 5000 psi (350 bar), although the pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength considerations. This cartridge valve exhibits low internal leakage and minimal pilot flow consumption thanks to its direct-acting design. The adjustment for increasing the setting involves up to five clockwise turns, with specific torque requirements for installation and locknut adjustments ensuring secure operation. The DRBPKEN weighs approximately .55 lb (.25 kg) and uses Viton seals within its cartridge assembly.

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.
