The Sun Hydraulics DRBMKDN (DRBMKDN) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or in conjunction with larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses a pre-set threshold. Notably, port 3 serves as a work port, and the flow path between ports 2 and 3 is bidirectional, enhancing its application flexibility. The direct-acting design ensures low internal leakage and minimal pilot flow consumption, making it an efficient choice for various hydraulic systems. Additionally, this cartridge features interchangeable direct-acting and pilot-operated versions that fit the same cavities and maintain consistent flow paths. The DRBMKDN model incorporates Sun's floating style construction to reduce the risk of internal parts binding due to excessive installation torque or cavity-cartridge machining variations. It has a maximum operating pressure of 5000 psi (350 bar) with a capacity of 7 gpm (28 L/min). The factory pressure settings are established at a flow rate of 4 gpm (15 L/min). For optimal performance, maximum pressure at port 3 should be limited to 3000 psi (210 bar), adhering to fatigue strength limits rather than hydraulic operating constraints. Installation specifications include a valve hex size of 7/8 in. (22.2 mm) and an installation torque range of 30 to 35 lbf ft (41 to 47 Nm). The adjustment screw has an internal hex size of 5/32 in. (4 mm), while the locknut hex size is set at 9/16 in. (15 mm) with a locknut torque specification between 80 to 90 lbf in. (9 to 10 Nm). The model weighs .55 lb (.25 kg) and uses Viton seal kits for enhanced durability and reliability in various operational environments.

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.
