The Sun Hydraulics DRBMKWN (DRBMKWN) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It serves as a switching device that can be utilized independently or to activate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses its set value. Port 3 functions as a work port, with bidirectional flow capability between ports 2 and 3. Thanks to its direct-acting design, the valve exhibits low internal leakage and minimal pilot flow consumption. It is interchangeable with pilot-operated versions, fitting the same cavities and maintaining identical flow paths. The DRBMKWN features Sun's floating style construction to reduce the risk of internal component binding due to excessive installation torque or machining variations in the cavity/cartridge. The maximum operating pressure is rated at 5000 psi (350 bar), while maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limitations. The valve has a capacity of 7 gpm (28 L/min) and factory pressure settings established at 4 gpm (15 L/min). It includes an adjustment mechanism allowing up to five clockwise turns to increase the setting. Installation specifics include a valve hex size of 7/8 inch (22.2 mm), installation torque range of 30 - 35 lbf ft (41 - 47 Nm), an adjustment screw internal hex size of 5/32 inch (4 mm), and locknut hex size of 9/16 inch (15 mm) with torque specifications of 80 - 90 lbf in (9 -10 Nm). The model weighs approximately .55 lb (.25 kg) and utilizes a Viton seal kit, part number 990021006.

Normally open, 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.
