The Sun Hydraulics DRBNKEN (DRBNKEN) is a normally closed, direct-acting, 2-way directional cartridge valve designed for use in moderate flow circuits. It serves as a switching device that can be used independently or to actuate larger pilot-operated directional or logic cartridges. This valve operates by shifting when the pressure differential between port 1 and port 4 exceeds a preset value. Port 3 can function as a work port, and the flow path between ports 2 and 3 is bidirectional. Thanks to its direct-acting design, the DRBNKEN features low internal leakage and minimal pilot flow consumption, making it efficient and reliable. Direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities with identical flow paths. The DRBNKEN incorporates Sun's floating style construction to reduce the risk of internal parts binding due to excessive installation torque or machining variations in cavity/cartridge designs. The valve has a maximum operating pressure of 5000 psi (350 bar) and should limit maximum pressure at port 3 to 3000 psi (210 bar) due to fatigue strength limits. It has a capacity of 7 gpm (28 L/min) with factory pressure settings established at 4 gpm (15 L/min). The valve's installation torque ranges from 30 to 35 lbf ft (41 to 47 Nm), with an adjustment screw internal hex size of 5/32 in. (4 mm). The DRBNKEN model weighs .55 lb (0.25 kg) and utilizes Viton seal kits for optimal performance.

Normally closed, direct-acting, 2-way directional cartridges 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.
- 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.
